Osteoarthritis ng Pulso

Overview¶

• Osteoarthritis of the hand and wrist requires an individualized approach to treatment strategies based on site-specific diagnoses and varying disease manifestations [1].
• In most scenarios, there is no single preferred option for wrist osteoarthritis [5].
• The choice of procedure for scaphotrapeziotrapezoidal joint osteoarthritis depends on whether the joint is isolated or associated with carpal malalignment and other joint osteoarthritis [7].
• Arthroplasty should be used as an alternative to arthrodesis in the treatment of posttraumatic wrist arthritis, given proper patient selection and indications [18].
• Wrist arthroplasty provides functional mobility, improved strength, and reduced pain in carefully selected cases of severely destroyed wrist joints [26].
• Implant survival rates for wrist arthroplasty do not compare with hip and knee arthroplasties [26].
• Motion-preserving procedures of the wrist can yield good long-term results if indications are accurately respected and the technique is well performed to prevent complications [58].
• Good functional outcomes and absence of osteoarthritis can be attributed to effective reduction and radiocarpal stabilization, along with the absence of radial and intracarpal marginal fractures [3].
• Ulnar head replacement and sigmoid notch resurfacing arthroplasty provide a feasible option for distal radial ulnar joint arthritis, resulting in substantial improvements in pain and function over short-term follow-up [4].
• Total wrist denervation is a reliable and reproducible surgical technique for pain relief and preservation of wrist function in painful osteoarthritis [19].
• Joint denervation deserves a place of choice in the surgical arsenal for osteoarthritis of the wrist and hand, provided new anatomical observations are integrated, the procedure is meticulous, and patients are informed that it is a symptomatic treatment [6].
• A second and even a third operation can result in long-term pain improvement, good function, and capacity for work in symptomatic cases with minor osteoarthritis of the wrist (SNAC stage 0 or 1) [21].

Anatomy & Pathophysiology¶

• Wrist alignment was maintained over time, but 13 patients presented mild to moderate symptomatic wrist arthritis following corrective osteotomy for distal radius malunion [2].
• Type I and III wrists in early rheumatoid arthritis exhibited radiographic progression and ultimately underwent deformation [12].
• Surgical treatments for scapholunate advanced collapse wrists resulted in decreased wrist kinematic motion and functional performance compared with individuals with normal wrists [33].
• Wrist biomechanics were significantly altered following trapeziectomy, with ligamentous reconstruction and tenodesis (LRTI) most closely resembling intact biomechanics in a cadaveric model [34].
• Motion was smoother and more closely replicated the normal axis and functional motion of the wrist in comparisons of 3- and 4-corner fusions [35].
• Computed fiber elongations of the dorsal carpal ligaments varied linearly with wrist position despite complex carpal bone anatomy and kinematics [36].
• Rotational malalignment of the wrist has significant effects on carpal, distal radial, and distal radioulnar joint measurements [37].
• Guidelines for measuring and quantifying carpal alignment three-dimensionally were established, providing a database for normal values useful in analyzing wrist pathologies and kinematics [38].
• Radioscapholunate fusion shows the most biomechanically similar behavior out of three fusion types compared with the healthy wrist [39].
• Tendon ball arthroplasty and proximal carpal stabilization with tendon graft for advanced Kienböck’s disease demonstrated reduced wrist pain, improved wrist motion and grip strength, and restored integrity of the proximal carpal row [40].
• Wrist range of motion within 20% extension and radial abduction to 50% flexion limits torque and lever force exacerbation between scaphoid fragments [42].
• The modification of the wrist center of rotation during flexion and extension was characterized, noting that stability is considered more important than mobility in clinical conditions [43].
• Wrist arthrodesis may only compromise select wrist functions [44].
• The 'dart thrower's motion' of the wrist, from radial extension to ulnar flexion, may be a unifying concept of functional wrist motion that is uniquely human [45].
• Total wrist replacement aims for a painless mobile wrist rather than a painless stiff wrist, evolving with advances in technology, materials, and understanding of biomechanics [46].
• Constant radiocarpal and midcarpal congruence during radioulnar deviation in normal wrists is no longer possible with intercarpal kinematic modifications after intercarpal arthrodeses [47].
• Persistent middle finger CMCJ micromotion was likely present in 19/20 wrists (95%) that experienced symptomatic hardware complications [48].
• Changes of the motion pattern of the lunate during radioulnar deviation and flexion-extension of the wrist after 4-corner arthrodesis explain the shift of the centroid radially and dorsally [49].
• SNAC wrists differ from SLAC wrists in exhibiting a decreased sagittal lunotriquetral angle, indicating a distinct pathomechanism of carpal instability [50].
• The 4-bone arthrodesis wrist has significantly lower contact pressure, greater contact area, and equal contact translation compared with the proximal row carpectomy wrist [51].

Classification¶

• Osteoarthritis of the hand and wrist requires an individualized approach to treatment strategies based on site-specific diagnoses and varying disease manifestations [1].
• The choice of procedure for osteoarthritis of the scaphotrapeziotrapezoidal joint depends on whether the joint is isolated or associated with carpal malalignment and other joint osteoarthritis [7].
• Type I and III wrists had radiographic progression and ultimately underwent deformation [12].
• Combining traditional qualitative evaluation and quantitative measurements may improve the classification of wrist osteoarthritis [14].
• Radiographic classification of SLAC wrist has moderate reliability and reproducibility [61].
• Classification of SNAC wrist has limited reliability [61].
• Reviewing multiview radiographs more commonly yielded Vender stage 3 osteoarthritis classification [62].

• A second and even a third operation can result in long-term pain improvement, good function and capacity for work, and re-operation is recommended in symptomatic cases with minor osteoarthritis of the wrist (SNAC stage 0 or 1) after failed surgery for scaphoid nonunion [21].
• Patients with wrist arthritis who undergo surgery face higher risks of CTS and subsequent CTR than those managed conservatively [22].
• Wrist radiographs demonstrate a 47% sensitivity and 94% specificity in predicting end-stage ST joint arthritis, emphasizing the importance of directly visualizing the ST joint after trapeziectomy in patients with end-stage carpometacarpal arthritis of the thumb base [25].
• Signal changes in the flexor carpi radialis are infrequent and often incidental or associated with peritrapezial osteoarthritis [27].
• In most patients, wrist function was improved and pain relief was obtained with the use of a pyrocarbon capitate resurfacing implant in chronic wrist disorders [41].
• Radio-scapho-capitate ligament reconstruction during proximal row carpectomy is a technique to consider, although one has to take into account the short-term follow-up of 1 year and the fact that the patient had rather low demands to his wrist [56].

• [L5] AVN of the carpal bones other than Kienböck disease is a rare cause of chronic wrist pain with a poorly understood natural history. [66] (10.1016/j.jhsa.2019.05.022)
• [L4] Radiological evaluation showed normal radiocarpal angles, volar tilt, and radial length in all patients. [67] (10.1007/s001670050172)
• [L4] The presence of radiological arthritis and static carpal instability did not cause reduced function at our minimum follow-up of 10 years. [68] (10.1016/j.jhsa.2009.09.003)
• [L4] Preoperative radiographs did not correlate well with intraoperative findings, often underestimating degenerative changes at the radiolunate joint. [69] (10.1016/j.jhsa.2014.03.032)
• [L4] Wrist denervation resulted in improvement in pain scores in 39 patients despite radiological deterioration noted in 34 after 6 years. [71] (10.1016/j.jhsa.2011.03.004)
• [L5] Postoperative progressive changes at the radiocapitate articulation have been documented, yet these changes tend to remain asymptomatic. [73] (10.1016/j.hcl.2012.08.022)
• [L4] With a majority of patients experiencing early radiographic failure of the procedure in the short term, our experience suggests that the reduction and association of the scaphoid and lunate procedure should be abandoned despite the relatively low outcomes measures scores.
