اس آپریشن کی تجویز کیوں کی گئی ہے

میٹر پرائیویٹ ہسپتال راک ہیمپٹن میں اوپری ٹانگوں کے سرجن ڈاکٹر کیران ہیرپارا کم سے کم جارحانہ اختیارات سے شروع کرتے ہیں جو آپ کی حالت کے مطابق ہیں۔ مریضوں کو عام طور پر ان کے جی پی کے ذریعہ ہمارے کلینک کا حوالہ دیا جاتا ہے۔ اگر کسی فزیوتھراپسٹ نے آپ کو ہمارے پاس آنے کی تجویز دی ہے تو ، آپ کو میڈیکیئر چھوٹ کے اہل ہونے کے ل your اپنے جی پی سے ریفرل کی ضرورت ہوگی۔ ہم آپ کی تاریخ کا جائزہ لیتے ہیں، آپ کی کلائی کا معائنہ کرتے ہیں، اور جہاں ضرورت ہو وہاں امیجنگ کا بندوبست کرتے ہیں تاکہ یہ معلوم کیا جا سکے کہ آپ کے درد کی وجہ کیا ہے۔

مٹھی کی جزوی فیوژن مٹھی کی چھوٹی ہڈیوں میں سے صرف کچھ کو ایک ساتھ جوڑتی ہے ، باقی کو حرکت میں رکھنے کے لئے چھوڑ دیتی ہے۔ یہ عام طور پر اس وقت پیش کیا جاتا ہے جب کلائی کے کسی حصے میں فرسودگی اور آنسو جوڑوں کی سوزش پیدا ہو چکی ہو، اکثر پرانی چوٹ کے بعد، اور دوسرے علاجوں سے کافی راحت نہیں ملی ہو۔ اس طرح کے دیرینہ مسائل کے لئے، ہم عام طور پر پہلے غیر جراحی کی دیکھ بھال کی کوشش کرتے ہیں: سرگرمی کی تبدیلی، فزیوتھراپی یا ہاتھ تھراپی، اور اسپلنٹنگ۔ جب اس سے کافی مدد نہ ملی ہو تو سرجری پر غور کیا جاتا ہے۔ آپریشن ایک بچاؤ کا طریقہ کار ہے، جس کا مطلب ہے کہ یہ استعمال کیا جاتا ہے جب آرتھرائٹس نے پہلے ہی مشترکہ کو نقصان پہنچایا ہے. اس کا بنیادی مقصد مٹھی کی زیادہ سے زیادہ حرکت ، گرفت کی طاقت اور استحکام کو برقرار رکھتے ہوئے درد کو دور کرنا ہے جیسا کہ باقی صحت مند مشترکہ اجازت دیتا ہے۔ ہم آپ کے ساتھ آپشنز کے ذریعے بات کریں گے اور مل کر فیصلہ کریں گے کہ آپ کی کلائی اور آپ کے مقاصد کے مطابق کیا ہے۔

آپریشن سے پہلے

آپریشن سے پہلے کے ہفتوں میں ہم آپ کی کلائی کی امیجنگ کا بندوبست کریں گے، جیسے ایکس رے یا ایم آر آئی اسکین، تاکہ ہم آپ کی کلائی کے ان حصوں کے ارد گرد آپریشن کی منصوبہ بندی کر سکیں جو ابھی بھی صحت مند ہیں۔ اس دن، آپ کو سات گھنٹے پہلے کھانا اور پینا چھوڑنا ہوگا۔ ہم کم وقت کے بجائے سات گھنٹے مانگتے ہیں تاکہ دن جلدی ختم ہونے کی صورت میں آپ کی جگہ تھیٹر کی فہرست میں آگے لائی جا سکے۔ آپ کو آپریشن سے پہلے اپنی کچھ باقاعدہ ادویات کو روکنے کی ضرورت ہوسکتی ہے۔ ہم آپ کو بتائیں گے کہ کون سے اور کب تک۔ براہ کرم آپ جو کچھ بھی لیتے ہیں اس کی ایک تحریری فہرست لائیں۔ اس کے بعد آپ کو گھر لے جانے کے لئے کسی سے انتظام کریں، اور ڈھیلے، آرام دہ کپڑے پہنیں۔ اگر آپ کے پاس دیگر طبی حالات ہیں، تو آپ کو دن سے پہلے خون کے ٹیسٹ یا اینستیکٹسٹ کے ساتھ جائزہ لینے کی ضرورت ہوسکتی ہے.

اس دن

آپ ہسپتال کے سرجیکل داخلہ یونٹ میں پہنچیں گے، جہاں آپ کی جانچ پڑتال کی جائے گی اور تھیٹر کے لئے تیار کیا جائے گا. آپ بیہوش کرنے والے ڈاکٹر سے ملیں گے جو آپ کو نیند میں ڈالتا ہے اور آپریشن کے دوران آپ کی دیکھ بھال کرتا ہے۔ یہ آپریشن عمومی اینستھیزیا کے تحت کیا جاتا ہے۔ آپ مکمل طور پر آپریشن کے لئے سو جائے گا. کچھ مریضوں میں آپریشن کے بعد درد سے نجات کے لئے علاقائی اعصابی رکاوٹ بھی ہوسکتی ہے۔ اینستھیزسٹ آپ کے انفرادی حالات کی بنیاد پر دن کا فیصلہ کرتا ہے۔ پھر آپ کو آپریشن تھیٹر میں لے جایا جاتا ہے، جہاں آپریشن کیا جاتا ہے۔

آپ ریکوری ایریا میں جاگیں گے، جہاں نرسیں آپ کی نگرانی کریں گی جب تک کہ اینستیک کا اثر ختم نہ ہو جائے۔ ایک بار جب آپ مستحکم ہو جاتے ہیں، آپ یا تو وارڈ میں جاتے ہیں یا گھر جاتے ہیں، طریقہ کار اور آپ کی بحالی پر منحصر ہے.

آپریشن میں کیا شامل ہے

آپ کا سرجن آپ کی کلائی کے پچھلے حصے میں ایک کٹ کے ذریعے کلائی کا جزوی فیوژن انجام دیتا ہے۔ اس سوراخ کے ذریعے آپ کا سرجن آپ کی کلائی کی چھوٹی ہڈیوں پر کام کرتا ہے۔ متاثرہ ہڈیوں کے درمیان ختم ہونے والی مشترکہ سطحوں کو صاف کیا جاتا ہے، اور کچھ خراب ہڈیوں کو ہٹا دیا جا سکتا ہے. آرتھرائٹس کے کچھ نمونوں میں، مثال کے طور پر، کلائی کے انگوٹھے کی طرف چھوٹی ہڈیوں میں سے ایک سکافائڈ کو مکمل طور پر نکال دیا جاتا ہے۔

ہڈیوں کو جوڑنے کے لیے چھوٹے دھاتی پیچ استعمال کیے جاتے ہیں۔ کچھ معاملات میں اس کے بجائے ایک چھوٹی سی پلیٹ استعمال کی جاتی ہے۔ آپ کی اپنی ہڈی کا ایک ٹکڑا، جو آپ کی کلائی کے قریب سے لیا گیا ہو، ہڈیوں کے درمیان رکھا جا سکتا ہے تاکہ وہ ایک ساتھ ٹھیک ہو جائیں۔ [ صفحہ ۲۲ پر تصویر] آپ کی باقی کلائی، وہ حصے جو ابھی بھی صحت مند ہیں، حرکت کرتے رہتے ہیں۔

ایک بار جب ہڈیاں صحیح پوزیشن میں ہوں اور مضبوطی سے رکھی جائیں تو آپ کا سرجن آپ کے زخم کو سلائیوں سے بند کر دیتا ہے اور اس پر پٹی باندھ دیتا ہے۔ پانسٹنگ تقریبا 10 دن تک رہتا ہے۔ 'آپریشن کے بعد' سیکشن میں بتایا گیا ہے کہ آگے کیا ہوتا ہے۔

آپ کی کلائی کے کس حصے میں گٹھیا ہے اس پر انحصار کرتا ہے کہ کون سی ہڈیاں اس میں شامل ہیں۔ آپ کا سرجن آپریشن کی منصوبہ بندی کرتا ہے جو پہلے سے لی گئی ایکس رے اور اسکینز کا استعمال کرتے ہوئے جوڑوں کے ارد گرد پہنا جاتا ہے جو پہنا جاتا ہے اور جو جوڑے ابھی بھی صحت مند ہیں. مقصد یہ ہے کہ تکلیف دہ، پہنی ہوئی سطحوں کو ہٹا دیا جائے جبکہ آپ کی باقی حرکتوں کی حفاظت کی جائے۔

آپریشن کے بعد

زیادہ تر مریض اس آپریشن کے بعد ایک رات اسپتال میں رہتے ہیں، حالانکہ کچھ اسی دن گھر جانے کے قابل ہوتے ہیں۔ آپ بحالی کے علاقے میں جاگ جائے گا، پھر وارڈ میں منتقل. نرسیں باقاعدگی سے آپ کا معائنہ کریں گی اور ضرورت کے مطابق آپ کو درد سے نجات دلائیں گی۔ آپ کی کلائی پر اسپلنٹ یا گلاس لگایا جائے گا اور زخم پر پٹی لگائی جائے گی۔ سوجن کے ساتھ مدد کرنے کے لئے آرام کرتے وقت اپنا ہاتھ تکیا پر اٹھائے رکھیں۔ آپ سرجری کے فوراً بعد اٹھ کر چل سکتے ہیں، اور اپنی انگلیاں، کہنی اور کندھے کو اپنی مرضی کے مطابق حرکت دے سکتے ہیں۔ براہ کرم گھر پہنچنے کے بعد پہلے 24 گھنٹوں کے لئے آپ کے ساتھ رہنے کے لئے کسی کا بندوبست کریں۔ ہم تقریباً 10 دن تک پانسٹنگ لگا کر رکھتے ہیں۔ براہ کرم اس سے پہلے اسے نہ اتاریں جب تک کہ ہم آپ کو ایسا نہ کہیں۔ جب ہم آپ کو دیکھیں گے تو ہم اسے تبدیل یا ہٹا دیں گے.

وصولی

پہلے چند دنوں میں آپ کی کلائی میں درد اور سوجن محسوس ہوگی۔ یہ آہستہ آہستہ حل ہو جاتا ہے. آپ کے ہاتھ تکیا پر اٹھائے رکھنے سوجن کو کم کرتا ہے، اور ہم آپ کو دے درد ریلیف مدد کرے گا. آپ اپنی انگلیوں، کوہنی اور کندھے کو حرکت دے سکتے ہیں جیسا کہ آرام کی اجازت دیتا ہے؛ یہ انہیں سخت ہونے سے روکتا ہے جبکہ آپ کی کلائی آرام کرتی ہے۔

آپ کی کلائی ایک سپلنٹ یا گلاس میں ہو گی جبکہ ہڈیاں ایک ساتھ شفا پائیں گی۔ آپریشن کے بعد ہاتھ تھراپی توسیع بحالی میں روبی Doolan ساتھ ہے. روبی ایک ہینڈ تھراپسٹ ہے: وہ آپ کی مشقوں کی رہنمائی کرے گی اور آپ کو جو بھی سپلنٹ درکار ہوگا وہ بنائے گی۔ تھراپی آہستہ آہستہ شروع ہوتی ہے، حرکتوں کے ساتھ جو شفا بخش ہڈیوں کی حفاظت کرتی ہے، اور فیوژن ٹھوس ہونے کے ساتھ بڑھتی ہے۔ آپ گھر کے زیادہ تر کام ایک ہاتھ سے کر پائیں گے، لیکن کچھ عرصے تک آپ کو بھاری کاموں میں مدد کی ضرورت ہوگی۔

ایک بار جب سوجن ختم ہو جائے اور آپ کا معالج آپ کو صاف کر دے، آپ کو کلائی تحریک اور گرفت پر کام کرنا شروع کر دیں گے. روزمرہ کی سرگرمیاں مرحلوں میں واپس آتی ہیں: پہلے ہلکے کام، پھر وہ کام جن میں زیادہ گرفت اور بوجھ کی ضرورت ہوتی ہے۔ جب تک آپ کا گلاس نہیں ہٹایا جاتا ہے اور آپ کا سرجن آپ کو صاف نہیں کرتا ہے اس وقت تک ڈرائیونگ کی اجازت نہیں ہے۔ اپر ٹانگ کی سرجری کے بعد ڈرائیونگ کے بارے میں ہمارا صفحہ دیکھیں۔ کام اور کھیل اپنی رفتار سے واپس آتے ہیں، جیسا کہ آپ کی طاقت اور آرام کی اجازت دیتا ہے.

صحت یابی ہر شخص سے مختلف ہوتی ہے۔ آپ کا ٹائم لائن مختلف ہوسکتا ہے۔ آپ کا سرجن اور تھراپسٹ آپ کی رہنمائی کریں گے۔

کیا غلط ہو سکتا ہے

زیادہ تر مریضوں کی حالت ٹھیک ہوتی ہے، لیکن کبھی کبھار مسائل پیدا ہو سکتے ہیں۔ آپ کا سرجن اور ٹیم آپ کو قریب سے مانیٹر کرتی ہے تاکہ کسی بھی مسئلے کا جلد پتہ چل سکے۔

بعض اوقات ہڈیاں ایک ساتھ مل کر ایک ٹھوس بلاک نہیں بنتی ہیں۔ آپ کو مٹھی میں گہرا، تکلیف دہ درد محسوس ہو سکتا ہے جو آرام نہیں کرتا، یا یہ محسوس ہوتا ہے کہ کچھ چل رہا ہے یا جہاں اسے مضبوط محسوس ہونا چاہئے وہاں پیس رہا ہے۔ اگلے معائنے میں یہ بات اٹھائیں، یا اگر درد بڑھ رہا ہے تو جلد ہی کلینک کو فون کریں۔

دھاتی پیچ یا پلیٹ بھی پریشانی کا سبب بن سکتی ہے۔ کچھ لوگوں کو جلد کے نیچے ایک تیز دھاگہ یا کلک محسوس ہوتا ہے، یا دھات پر درد ہوتا ہے جو استعمال کے ساتھ بھڑکتا ہے۔ اگر ایسا ہوتا ہے، تو ہارڈ ویئر کو ایک چھوٹا سا آپریشن میں لے جایا جا سکتا ہے. اپنے جائزہ ملاقات میں اس کا ذکر کریں.

انفیکشن غیر معمولی ہے لیکن فوری توجہ کی ضرورت ہے. زخم سے پھیلنے والی لالی، گرمی، بڑھتی ہوئی سوجن، یا بینڈیشنگ سے بہہ جانے پر نظر رکھیں۔ آپ کو بخار یا عام طور پر بیمار محسوس ہوسکتا ہے۔ اگر آپ کو ان علامات میں سے کوئی بھی نظر آئے تو فوری طور پر کلینک کو کال کریں، یا اگر یہ گھنٹوں کے بعد ہے یا سرخیاں تیزی سے پھیل رہی ہیں تو ایمرجنسی ڈپارٹمنٹ میں جائیں۔

آپریشن کے بعد سوجن کی وجہ سے کلائی کے سامنے سے گزرنے والا اعصاب دباؤ میں آ سکتا ہے۔ یہ انگوٹھے، انڈیکس اور درمیانی انگلیوں میں خارش، پن اور انجکشن یا numbness کا سبب بنتا ہے، اور یہ رات کو بدتر محسوس کر سکتا ہے. اگر آپ ان تبدیلیوں کو محسوس کرتے ہیں تو اپنے سرجن کو فوری طور پر بتائیں، کیونکہ دباؤ کو دور کرنے کے لئے ایک چھوٹا سا آپریشن کی ضرورت ہوسکتی ہے.

آرتھرائٹس کبھی کبھی جوڑوں میں ترقی کر سکتا ہے جو اب بھی چل رہے ہیں. آپ کو مہینوں یا سالوں کے بعد دوبارہ درد یا سختی محسوس ہوسکتی ہے، یا کلائی میں نئی رگڑ۔ یہ آپ کے جائزہ میں اٹھائیں تاکہ یہ تازہ ایکس رے کے ساتھ چیک کیا جا سکتا ہے.

شاذ و نادر ہی ، جزوی فیوژن کافی ریلیف نہیں دیتا ہے اور اس کے بجائے کلائی کا مکمل فیوژن پیش کیا جاتا ہے۔ یہ ایک بڑا آپریشن ہے جو کلائی کی نقل و حرکت کو روکتا ہے لیکن اس کا مقصد درد کو دور کرنا ہے۔ آپ کا سرجن آپ سے اس بارے میں بات کرے گا اگر کبھی ایسا ہو جائے۔

اگر آپ تفصیلات چاہتے ہیں تو اس صفحے پر پیچیدگیوں کی میز عام شرحوں کی فہرست دیتی ہے۔

ہمیں کب کال کریں

ہمیں کال کریں اگر آپ کو بخار ہے، یا اگر آپ کے زخم کے ارد گرد کی جلد سرخ ہو جاتی ہے، گرم ہو جاتی ہے یا چھلکنا شروع ہو جاتی ہے۔ اگر آپ کا درد اچانک بڑھ جاتا ہے یا کم نہیں ہوتا ہے تو ہمیں کال کریں۔ اگر آپ کے پاوں میں سوجن یا درد ہو یا سانس کی قلت ہو تو ہنگامی حالت میں جائیں۔ اگر آپ کے ہاتھ میں احساس کھو جاتا ہے یا آپ کی انگلیوں، کلائی یا بازو کو منتقل نہیں کر سکتے ہیں تو ہنگامی حالت میں جائیں. اگر یہ گھنٹوں کے بعد ہے اور آپ پریشان ہیں تو، انتظار کرنے کے بجائے ایمرجنسی میں جائیں. جب شک ہو تو ہمیں کال کریں؛ ہم آپ کو گھر میں کسی مسئلے پر بیٹھنے کے بجائے آپ سے سننا پسند کریں گے۔

اس حالت کے بارے میں مزید کہاں سے پڑھ سکتے ہیں

Anatomy & Pathophysiology

Bony Anatomy

  • The wrist includes the distal radioulnar, radiocarpal, and ulnocarpal joints and the eight carpal bones and their proximal and distal articulations and attached ligaments [41].
  • The proximal row of carpal bones consists of the scaphoid, lunate, triquetrum, and pisiform [41].
  • The distal row of carpal bones consists of the trapezium, trapezoid, capitate, and hamate [41].
  • The pisiform and trapezoid are the smallest carpal bones, while the capitate is the largest [41].
  • The capitate articulates with seven other carpal bones, while the pisiform articulates with only one [41].
  • The radiocarpal joints are formed by the articulation of the distal radius with the scaphoid and lunate through their respective concave facets on the distal radius and the triquetrum on the triangular fibrocartilage [41].
  • The distal concave articular surfaces of the proximal carpal row form the midcarpal articulations with the distal row [41].
  • The distal row articulates with the metacarpals, allowing mobility in the thumb, stability in the index and long finger metacarpals, and increased mobility in the ring and little finger metacarpals [41].
  • The distal ulnar convexity articulates at the lesser sigmoid notch of the distal radius [41].
  • The sigmoid notch articular surface accommodates the ulnar head through two thirds of its arc [41].
  • There is about a 20-degree inclination of the distal ulna at its articulation with the radius [41].
  • The distal radius has three articular components: the scaphoid and lunate fossae, and the sigmoid notch [45].
  • Between the scaphoid and the lunate fossa is a ridge that corresponds with the scapholunate interval [45].
  • The concave elliptical distal radius is oriented in the sagittal plane with an average of 11 degrees of volar tilt [45].
  • In the frontal plane, the average radial inclination of the distal radius is 23 degrees [45].
  • Radial length is measured from the tip of the radial styloid to the ulnar articular surface and averages 13 mm [45].
  • The radius has a lateral bow that is crucial to the maintenance of full pronation and supination [45].

Ligamentous Anatomy

  • Extrinsic carpal ligaments connect the radius or the ulna to the carpus [46].
  • In general, the volar ligaments are stronger than the dorsal ligaments [46].
  • The radioscaphocapitate ligament connects to the waist of the scaphoid, around which the scaphoid rotates, and limits ulnar translation of the carpus [46].
  • The long radiolunate ligament helps to limit ulnar translocation of the carpus [46].
  • The short radiolunate ligament helps control lunate position [46].
  • The radioscapholunate ligament is a vascular conduit, not a true ligament, also known as the ligament of Testut [46].
  • The ulnocapitate ligament attaches to the ulnar head and is the most superficial or palmar of the palmar ulnocarpal ligaments [46].
  • The dorsal radiocarpal ligament has a trapezoidal shape and passes from the dorsal rim of the distal radius to the lunate and the triquetrum [46].
  • The dorsal radiocarpal ligament fibers insert onto the dorsal lunotriquetral interosseous ligament [46].
  • Damage to the dorsal radiocarpal ligament, when in conjunction with other intrinsic ligament injuries, confers further carpal instability [46].
  • The scapholunate interosseous ligament is the major stabilizer of the wrist and the most commonly injured wrist ligament [46].
  • The scapholunate interosseous ligament is C-shaped, consisting of dorsal, palmar, and interosseous portions, with the dorsal portion being the strongest and thickest [46].
  • The scapholunate interosseous ligament provides a flexion force on the lunate given its attachment to the scaphoid [46].
  • The lunotriquetral interosseous ligament is C-shaped, where the volar portion is the thickest and strongest [46].
  • The lunotriquetral interosseous ligament provides an extension moment on the lunate given its attachment to the triquetrum [46].
  • The capitohamate ligament is a thick ligament, 5 × 5 mm in cross section, with extensions to the third or fourth metacarpals [46].
  • The dorsal intercarpal ligament passes from the dorsal tubercle of the triquetrum to the distal pole of the scaphoid [46].
  • The dorsal intercarpal ligament reinforces the elastic dorsal wrist capsule and helps stabilize the scapholunate articulation with a contribution to the dorsal scapholunate interosseous ligament from its deep fibers [46].
  • The space of Poirier is an area adjacent to the proximal capitate without ligamentous attachment, situated ulnar to the radioscaphocapitate ligament and radial to the long radiolunate in the floor of the carpal tunnel [46].
  • The space of Poirier is a weak area that is vulnerable to instability, and the distal carpal row separates from the lunate through this space during a perilunate dislocation [46].
  • The triangular fibrocartilage complex attaches to the ulnar margin of the lunate fossa of the radius and includes the ulnar collateral ligament, dorsal and volar radioulnar ligaments, articular disc, meniscal homologue, extensor carpi ulnaris sheath, and ulnolunate and ulnotriquetral ligament [41].
  • The interosseous membrane connects the shafts of the radius and ulna, with a thickened central portion important in force transmission between the radius and ulna [45].

Biomechanics and Kinematics

  • The wrist joint’s motion planes include flexion, extension, radial deviation, ulnar deviation, and circumduction [46].
  • There is minimal carpal motion with pronosupination [46].
  • Approximately 62° of wrist extension occurs through the radiocarpal joint [46].
  • 62% of wrist flexion occurs through the midcarpal joint [46].
  • The midcarpal joint is mostly responsible for 20° and 40° of radial and ulnar deviation, respectively [46].
  • The midcarpal joint is responsible for the “dart thrower’s motion,” which involves moving from radial extension into ulnar flexion positioning of the wrist [46].
  • The radius bears 80% of the axial load transmitted through the radiocarpal joint, while the ulna bears 20% in neutral ulnar variance [46].
  • The proximal row of carpal bones forms an intercalated segment between the distal carpal row and the distal radius and is bound into a functional unit by the scapholunate and lunotriquetral interosseous ligaments [46].
  • The distal row is rigid, with little motion between its bones due to stout intercarpal ligaments, and acts as a functional unit with the scaphoid bridging both rows [46].
  • During wrist flexion from neutral, the distal row flexes and ulnarly deviates slightly while the scaphoid pronates [46].
  • During wrist flexion from neutral, the proximal row flexes differentially, with more rotation through the scaphoid, followed by the triquetrum and the lunate [46].
  • During wrist flexion from neutral, the proximal row translates dorsally [46].
  • During wrist extension from neutral, the distal row extends and radially deviates slightly while the scaphoid supinates [46].
  • During wrist extension from neutral, the proximal row extends differentially, with more motion in the scaphoid, followed by the triquetrum and then the lunate [46].
  • During wrist extension from neutral, the proximal row translates palmarly [46].
  • Between 30% and 50% of sagittal motion at the wrist occurs through the midcarpal joint, with the remainder through the radiocarpal joint [14].
  • The eight carpal bones represent the most complex articular system in the human body, each capable of moving in different degrees or directions dependent on the position, motion, and force generation of the hand in space [42].
  • The human wrist allows precise positioning of the hand and optimization of power and prehensile tasks throughout a nearly hemispherical arc of wrist motion [42].
  • Injuries to the wrist mechanism can lead to instability, resulting in a painful lack of motion, strength, and function [42].

Innervation

  • The anterior and posterior interosseous nerves innervate the central two-thirds of the anterior and posterior carpal joint capsule, respectively [24].
  • The anterior and posterior interosseous nerves pass within 2 mm of each other just proximal to the distal radioulnar joint capsule, separated only by the interosseous membrane of the forearm [24].
  • Partial denervation of the wrist reduces pain stemming from intra-articular pathology by resecting peripheral nerves whose terminal fibers innervate only the joint capsule [24].

Classification

  • Total wrist fusion should only be used for exceptional circumstances [2].
  • The choice of procedure depends on the pattern of wrist destruction and stability [3].
  • Radiolunate arthrodesis is effective for unstable wrists with preserved midcarpal joint space [3].
  • Good and excellent clinical results in the majority of patients following radiolunate fusion do not depend on the fixation device [4].
  • Radioscapholunate (RSL) fusion is a palliative procedure that preserves some of the wrist's mobility [5].
  • Radioscapholunate (RSL) fusion has a significant nonunion rate [5].
  • Nonspanning arthrodesis is advocated as an alternative method for total wrist fusion with a high union rate and minimal risk of complications at the carpometacarpal joint [6].
  • There is a low rate of conversion to total wrist arthrodesis following scaphoid excision and four-corner arthrodesis [7].
  • Proximal row carpectomy (PRC) simplifies total wrist arthrodesis by obviating the need for an iliac bone graft [9].
  • PRC performed concomitantly with total wrist arthrodesis in patients with rheumatoid arthritis produces good clinical and radiological outcomes without inducing loss of strength or digital deformities [9].
  • The healing rate for total wrist arthrodesis combined with PRC was 92% (35/38 wrists) [9].
  • No effects of carpal height loss on clinical or radiographic parameters were detected in patients undergoing total wrist arthrodesis combined with PRC [9].
  • Patients undergoing proximal row carpectomy experienced good pain relief with preservation of wrist motion [10].
  • Results for total wrist arthrodesis were slightly in favour of patients with a primary wrist arthrodesis compared to salvage of failed total wrist arthroplasty [11].
  • Complications and reoperations occur frequently in total wrist arthrodesis, most often due to incomplete bone fusion or hardware-related problems [16].
  • It remains unknown which implant type is best for total wrist arthrodesis or if the carpometacarpal joint should be included [16].
  • Proximal row carpectomy (PRC) and four-corner arthrodesis (FCA) demonstrated similarly low rates of conversion to total wrist arthrodesis [18].
  • Intercarpal arthrodesis is performed most commonly for the treatment of arthritis and carpal instability [19].
  • The objective of intercarpal arthrodesis is minimizing or eliminating pain while maximizing motion and function [19].
  • These goals are achieved by removing arthritic joint surfaces and by altering carpal motion and load transference [19].
  • Some intercarpal fusion procedures have good, predictable outcomes with maintenance of results over time [19].
  • Other intercarpal fusion procedures are infrequently used or of primarily historical interest owing to unpredictable results and high rates of complications [19].
  • Proximal row carpectomy is a motion-preserving salvage procedure with a low rate of conversion to wrist arthrodesis [23].
  • Joint arthrodesis procedures evaluated for the impact of smoking on delayed osseous union include complete wrist, carpometacarpal joint, metacarpophalangeal joint, proximal interphalangeal joint, distal interphalangeal joint, scaphoid excision/4-corner arthrodesis, and other limited carpal fusions [28].
  • Union in upper extremity arthrodesis is defined as the appearance of trabeculae crossing the arthrodesis site on at least 2 of 4 cortices viewed on orthogonal radiographs [28].
  • Cases that failed to demonstrate union across the arthrodesis site by 90 days after surgery are classified as delayed unions [28].
  • Total wrist arthrodesis was performed in three patients for secondary arthrosis and in another three patients for progressive arthritic destruction following radiolunate arthrodesis [30].
  • Radiographic changes following proximal row carpectomy were not significantly correlated with clinical findings, objective and subjective outcome measures, or time from surgery [39].
  • A functional arc of wrist motion was maintained as measured by the flexion/extension arc and radial/ulnar deviation in all patients after at least 10 years follow-up following proximal row carpectomy [39].
  • There was a significant decrease in grip strength following proximal row carpectomy [39].
  • Upper extremity function as measured by the DASH and PRWE scores following proximal row carpectomy compared favorably with those reported postoperatively following four-corner arthrodesis [39].
  • Patients who underwent total wrist fusion (TWF) after radioscapholunate fusion were considered as having poor clinical outcomes [73].
  • Prognostic factors for good clinical outcome after radioscapholunate fusion are assessed based on global pain, wrist motion, and grip strength [73].
  • Good clinical result after radioscapholunate fusion corresponds to global pain of none or slight (VAS ≤ 3) [73].
  • Good clinical result after radioscapholunate fusion corresponds to functional wrist motion including flexion ≥ 5 degrees, extension ≥ 30 degrees, radial deviation ≥ 10 degrees, and ulnar deviation ≥ 15 degrees [73].
  • Good clinical result after radioscapholunate fusion corresponds to grip strength of at least 50% of the contralateral side [73].
  • Poor clinical result after radioscapholunate fusion corresponds to global pain of moderate or severe (VAS > 3) [73].
  • Poor clinical result after radioscapholunate fusion corresponds to nonfunctional motion in at least one direction [73].
  • Poor clinical result after radioscapholunate fusion corresponds to grip strength of less than 50% of the contralateral side [73].
  • Signs of osteoarthritis development following limited intercarpal fusion or proximal row carpectomy are graded in five categories (none, doubtful, mild, moderate, and severe arthritis) according to the Kellgren-Lawrence Classification System [76].
  • Results of 4-corner arthrodesis using headless compression screws were comparable to or better than previously published techniques in terms of fusion rates, alleviation of pain, grip strength, range of motion, Mayo wrist score, and Disabilities of the Arm, Shoulder, and Hand questionnaire score [77].

Clinical Presentation

Investigations

Imaging Modalities

  • MRI is the modality of choice for imaging radiographically occult fractures of the hand and wrist [47].
  • The primary advantages of MRI compared with CT and radiography are improved tissue characterization, especially of soft tissues such as ligamentous structures in the wrist and synovium in the hand, and the lack of ionizing radiation [47].
  • 3T MRI is much preferred for hand and wrist imaging, especially for imaging small fields of view [47].
  • MRI with contrast enhancement is most commonly used to determine whether soft-tissue lesions are solid or cystic or, in the case of rheumatologic imaging, to better visualize erosions and synovial burden [47].
  • MR arthrography can be performed for evaluation of the triangular fibrocartilage and intercarpal ligament tears, but this is generally unnecessary with the increasing availability of high field MRI [47].
  • 26-33% of scaphoid fractures were judged nondisplaced on radiograph, but displaced on CT scan [81].

Kinematics and Biomechanics

  • A study quantifies a normative range of median radiolunate interosseous proximities during wrist motion [33].

Treatment

Arthrodesis Techniques and Outcomes

  • Radiolunate arthrodesis is effective for unstable wrists with preserved midcarpal joint space in the rheumatoid wrist [3].
  • Radioscapholunate fusion is a palliative procedure that preserves some wrist mobility but has a significant nonunion rate [5].
  • Nonspanning arthrodesis is an alternative method for total wrist fusion with a high union rate and minimal risk of complications at the carpometacarpal joint [6].
  • Scaphoid excision and four-corner arthrodesis for advanced carpal collapse has a low rate of conversion to total wrist arthrodesis [7].
  • Wrist arthrodesis is a well-established procedure that predictably relieves pain and provides a stable wrist for power grip [35].
  • Plate fixation offers little benefit over previous stabilization techniques when performing scaphoid excision and four-corner fusion [29].
  • Radioscapholunate arthrodesis with compression screws and local autograft achieves a 100% union rate at mean follow-up of 12 months with no complications in appropriately selected patients with a preserved midcarpal joint [62].
  • Wrist arthrodesis with bone autograft and Hoffmann external fixation results in patients regaining full finger movements and rotation of the forearm, though complete pain relief is rare and patients have significant limitations in activities of daily living [80].
  • Complications and reoperations following total wrist arthrodesis occur frequently, most often due to incomplete bone fusion or hardware-related problems [16].
  • The lateral or radial approach for wrist arthrodesis avoids the distal radio-ulnar joint, preserving some useful pronation and supination [32].
  • The lateral or radial approach for wrist arthrodesis avoids involvement of the extensor mechanism, allowing for faster mobilization of finger extensors [32].
  • The lateral or radial approach for wrist arthrodesis preserves the normal appearance of the wrist and avoids the thickening commonly seen with the dorsal or medial approach [32].
  • Between 10 to 15 degrees of dorsiflexion with slight ulnar deviation is the optimum position for wrist arthrodesis, aligning the shaft of the second metacarpal with the distal end of the radius [32].
  • The second and third carpometacarpal joints are recommended to always be included in wrist arthrodesis to prevent abnormal painful motion [32].
  • Proximal row carpectomy performed concomitantly with total wrist arthrodesis in rheumatoid arthritis produces good clinical and radiological outcomes without inducing loss of strength or digital deformities [9].
  • In a study of 38 total arthrodeses of rheumatoid wrists combined with proximal row carpectomy, the healing rate was 92% (35/38 wrists) [9].
  • In a study of 38 total arthrodeses of rheumatoid wrists combined with proximal row carpectomy, the mean VAS pain score was 0.4 and the mean PRWE score was 21 [9].
  • In a study of 38 total arthrodeses of rheumatoid wrists combined with proximal row carpectomy, grip strength was 76% of the contralateral limb [9].
  • No effects of carpal height loss on clinical or radiographic parameters were detected in total wrist arthrodesis combined with proximal row carpectomy [9].

Proximal Row Carpectomy

  • Patients undergoing proximal row carpectomy experience good pain relief with preservation of wrist motion [10].
  • For stage II SLAC wrist with a preserved capitolunate joint, proximal row carpectomy is preferred because it is technically less demanding and yields durable results [61].
  • Proximal row carpectomy using decellularized dermal allograft expands the indications for PRC to include select patients with degeneration of the capitate head [17].

Arthroplasty and Cost-Effectiveness

  • Total wrist arthroplasty and total wrist arthrodesis are both extremely cost-effective procedures [25].
  • Newer fourth-generation wrist implants appear to be performing better than earlier designs [21].
  • Arthroplasty should be used as an alternative to arthrodesis in the treatment of posttraumatic wrist arthritis, given proper patient selection and indications [69].
  • Although total wrist arthrodesis and partial wrist arthroplasty are attractive treatment options for the painful arthritic wrist, there remains a noteworthy potential for complications requiring additional surgery [8].

Denervation

  • Simple PIN wrist denervation offers comparable pain relief and functional benefits to wrist arthrodesis in the painful rheumatoid wrist [37].
  • Arthroscopic radial styloidectomy provides significant pain relief and facilitates early functional recovery [79].

Complications

Nonunion and Conversion to Total Wrist Arthrodesis

  • Proximal row carpectomy and four-corner arthrodesis demonstrated similarly low rates of conversion to total wrist arthrodesis [18].

  • Subsequent total wrist arthrodesis was performed in 135 patients (2.67%) who had a previous four-corner fusion [51].
  • Subsequent total wrist arthrodesis was performed in 65 patients (1.79%) with a previous proximal row carpectomy [51].
  • Twelve patients had undergone a wrist arthrodesis following proximal row carpectomy in a cohort with an average follow-up of 19.8 years [31].

  • Total wrist arthrodesis was performed in three patients for progressive arthritic destruction at 44, 63, and 72 months after primary radiolunate arthrodesis [30].
  • An approximate 10% risk of secondary wrist arthrodesis exists in patients with persistent or progressive ulnar wrist pain following partial wrist denervation [12].

Hardware and Fixation Complications

  • Seventy-five (1.48%) patients required a secondary procedure for removal of symptomatic fusion hardware after the index four-corner fusion procedure [51].
  • Including both hardware removal and subsequent total wrist arthrodesis, 220 (4.16%) of four-corner fusion patients required a secondary procedure [51].
  • The Spider plate showed 100% fusion rates in the first documented series for scaphoid excision with four-corner fusion [86].
  • Hardware complications were common in wrist arthrodesis for cerebral palsy, leading to a recommendation for routine hardware removal [90].
  • The complication rate was low, and the hardware did not have to be removed in most cases following modified Clayton-Mannerfelt arthrodesis [85].
  • One patient's pain was relieved by removal of a screw which protruded into the midcarpal joint space 12 months after primary radiolunate arthrodesis [30].
  • In three patients, a screw protruded into the midcarpal joint space and induced arthrosis following radiolunate arthrodesis [30].
  • Fracture of a plate led to secondary osseous union in ulnar translation following radiolunate arthrodesis [30].
  • There were seven complications reported in a series of 91 radiolunate arthrodesis cases, including one superficial wound problem, two fractures, and four displacements or malplacements of osteosynthetic material [30].

Infection and Other Complications

  • Infection following wrist arthroplasty and arthrodesis is relatively uncommon in a nationally representative Medicare database cohort [89].
  • Although total wrist arthrodesis and partial wrist arthroplasty are attractive treatment options, there remains a noteworthy potential for complications requiring additional surgery [8].
  • Cautious patient selection and consideration of potential complications are crucial for good outcomes in wrist arthrodesis and soft tissue rebalancing in the spastic hand [88].
  • Radiographic follow-up beyond 2 years following proximal row carpectomy revealed joint narrowing and arthritic changes within the radiocapitate joint [31].
  • Of 82 patients in five studies where radiographic data was available following proximal row carpectomy, 65 had evidence of radiocapitate degenerative joint disease (79.3%) [39].
  • Forty-six patients (74%) were not satisfied with the results of their proximal row carpectomy surgery due to persistent pain or inability to return to previous occupational activities [31].
  • Fifty-two patients required daily pain medication for wrist pain following proximal row carpectomy [31].

Recovery

Functional Outcomes and Patient Satisfaction

  • Most patients report satisfactory functional outcomes despite the loss of wrist motion, confirming they are able to accomplish most daily activities of living with some adaptation and compensation [20].
  • Total wrist arthrodesis provides reliable pain relief and good functional outcomes with high patient satisfaction, particularly for end-stage arthritis and as a salvage technique [13].
  • At a mean follow-up of 6 years following four-corner arthrodesis with a dorsal locking plate, pain was significantly reduced and wrist function was significantly improved compared with preoperative status [83].
  • Four-corner bone wrist arthrodesis by dorsal rectangular plating achieves an acceptable preservation of range of motion with good pain relief [87].

Union and Complications

  • Four-corner bone wrist arthrodesis by dorsal rectangular plating achieves an excellent consolidation rate and minimal complications [87].
  • Radioscapholunate fusion is a palliative procedure that preserves some of the wrist's mobility but has a significant nonunion rate [5].
  • Nonspanning total wrist arthrodesis with a low-profile locking plate is advocated as an alternative method for total wrist fusion with a high union rate and minimal risk of complications at the carpometacarpal joint [6].

Conversion and Salvage Rates

  • Proximal row carpectomy and four-corner arthrodesis demonstrated similarly low rates of conversion to total wrist arthrodesis for Stage-II SLAC/SNAC arthritis [18].

Alternative Procedures and Long-term Data

  • The results between patients undergoing salvage total wrist arthrodesis for failed total wrist arthroplasty and those undergoing primary wrist arthrodesis were slightly in favour of patients with a primary wrist arthrodesis [11].
  • Robust long-term follow-up data on wrist arthroplasty are not yet available, although functional improvement was observed for arthroplasty patients [22].
  • Findings suggest an approximate 10% risk of secondary wrist arthrodesis in patients with persistent or progressive ulnar wrist pain following partial wrist denervation in inflammatory arthritis [12].
  • Additional studies are required to confirm findings and investigate who may benefit from partial wrist denervation in wrist osteoarthritis [15].

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
