PDF Evidence

Isang protektadong plano ng paggaling pagkatapos ng pagsusuri ng fracture ng scaphoid gamit ang isang buried headless compression screw, na nagpapadali sa pagbabalik ng wrist sa galaw nang maaga sa ilalim ng proteksyon ng screw habang ang mabagal na gumagaling na buto ay nag-uunite, pagkatapos ay pagpapalakas ng grip at lakas, habang ang pagloload at mga sports na may kontak ay pinipigilan hanggang sa kumpirmado ang pag-uunite.

Ano ang inaasahan

Ang scaphoid ay isang maliit na buto sa sahig ng pulso na nag-uugnay sa dalawang hanay ng mga buto ng pulso. Ito ay may hindi karaniwang at mahina na suplay ng dugo na pumapasok dito mula sa likod, mula sa isang dulo patungo sa kabilang dulo, kaya ang isang fracture ng scaphoid ay mabagal ang paggaling at, kung iiwan lang, ay minsan ay maaaring hindi mag-ugnay (isang nonunion). Ang scaphoid fixation ay pinipigilan ang dalawang piraso ng buto nang mahigpit gamit ang isang headless compression screw na lubos na nakatago sa loob ng buto; walang nararamdaman o kailangang alisin. Ang screw ay pumipiga sa fracture, na tumutulong sa paggaling nito at nagbibigay-daan upang magsimula ang paggalaw ng pulso nang mas maaga kaysa sa isang fracture na ginagamutan lamang sa pamamagitan ng plaster cast. Kung ang fracture ay lumang panahon na o hindi pa nag-ugnay, maaaring magdagdag ng maliit na piraso ng bone graft (karaniwang kinukuha mula sa malapit na buto ng forearms) upang hikayatin ang paggaling; maaaring gawing mas maingat ang unang plano.

Ang pangunahing ideya ng paggaling na ito ay ang screw ang nagsisilbing hawak habang ang buto ay dahan-dahang nag-uugnay. Dahil mabagal ang paggaling ng scaphoid, ang mga milestone sa planong ito ay sinusunod sa kung paano nagugaling ang buto, hindi lamang base sa kalendaryo. Karaniwang kumpirmahin ng iyong surgeon na ang fracture ay nag-ugnay na ("union") sa pamamagitan ng X-ray, at madalas ay isang CT scan, bago ka bigyan ng pahintulot para sa mas mabigat na paggamit at sports. Kung gaano kabilis ka mag-progres ay nakadepende sa uri at posisyon ng fracture (isang break malapit sa mabagal na paggaling na itaas, o "proximal pole", at isang nakaraang nonunion ay mas maingat) at sa kung gaano katatag ang fixation.

Ang paggalaw ay binubuksan sa maingat na yugto: paggalaw ng daliri at hinlalaki agad; banayad na paggalaw ng pulso kapag pinayagan ng iyong hand therapist; pagkapanatili at pagpapalakas lamang pagkatapos ang buto ay mag-ugnay; at pagbabalik sa loaded o contact sport sa huli. Dahil ang repair ay patuloy na nagninilay para sa mga buwan, ang mas mabigat na paggamit at sports ay binubuo nang dahan-dahan imbes na sabay-sabay.

Mga Paalala at Limitasyon

  • Suotin ang iyong splint o cast ayon sa utos at panatilihing tuyo. Sabihin ni Dr. Hirpara at ng iyong hand therapist kung kailan dapat itong tanggalin para sa mga ehersisyo at kung kailan ito ay maaaring iwan.
  • HUWAG humawak nang mahigpit, magbuhat, magdala o itulak sa pamamagitan ng pulso hangga't hindi pa sinasabi na ang fracture ay nag-union na; ang pagpipigil at pag-load ay nagdudulot ng tensyon sa scaphoid at sa screw habang ang buto ay nagpapagaling pa.
  • Iwasan ang pagpilit ng pulso pabalik sa buong backward bend (extension) at iwasan ang mga extremes ng galaw sa maagang yugto; dahan-dahang pumasok sa range, huwag pilitin ang dulo nito.
  • HUWAG bumalik sa contact, collision o load-bearing sport (o sa gym/weights, push-ups, racquet o stick sports) hangga't hindi kumpirmado ng iyong surgeon na ang buto ay nakakabit at hindi pa ito pinapayagan; ito ay karaniwang buwan, hindi linggo.
  • Panatilihing gumagalaw ang iyong mga daliri, hinlalaki, siko at balikat mula sa simula upang hindi ito maging stiff, at gamitin ang kamay para sa magaan na pang-araw-araw na gawain sa loob ng comfort, hangga't ito ay hindi kasama ang paghawak nang mahigpit, pagbuhat o pagpilit ng pulso.
  • Kung ang iyong fixation ay gumamit din ng bone graft para sa nonunion, maghanda para sa mas maingat na timeline; sundin ang partikular na plano na ibinigay ng iyong surgeon at hand therapist.

Para sa wound, swelling at scar management, tingnan ang wound care guidance ng practice.

Mga ehersisyo ninyo

Ito ang mga ehersisyo mula sa inyong handout. Simulan lamang ito ayon sa gabay ni Dr. Hirpara at ng inyong hand therapist, at manatili sa loob ng anumang range at limitasyon na ibinigay sa inyo. Ang mga maagang ehersisyo ay pinapanatiling galaw ang mga daliri, hinlalaki, at forearms nang hindi nakakaapekto sa paggaling ng scaphoid, at ang banayad na galaw ng pulso ay idadagdag lamang kapag pinayagan na ng inyong therapist. Ang pagpapalakas ng grip ay kabilang sa mas huling yugto at hindi dapat simulan hangga’t hindi ninyo sinasabing nag-union na ang buto. Itigil ang anumang nagdudulot ng matulis na sakit sa pulso, at ipaalam ito sa inyong therapist.

Ang iyong klinikal na protokol

Ang natitirang bahagi ng pahinang ito ay ang yugto-yugto na klinikal na protokol para sa rehabilitasyon pagkatapos ng pagkukumpuni ng scaphoid gamit ang headless compression screw. Ang seksyong ito ay dapat ibigay sa hand therapist ng pasyente, at bawat yugto ay nagsisimula sa isang paliwanag sa simpleng wikang Ingles tungkol sa nangyayari. Mabagal ang paggaling ng scaphoid dahil sa mahina nitong retrograde na suplay ng dugo, kaya ang pag-unlad ay gated sa union at depende sa fixation at fracture: ang matibay na pagkukumpuni ng screw sa isang matatag na acute na fracture sa waist ay nagpapahintulot ng mas maagang protektadong galaw ng pulso, samantalang ang mga fracture sa proximal pole, nonunions, at mga kaso na may bone graft ay nangangailangan ng mas maingat na proseso.

Bago magsimula ang paggamot, suriin ang operation report at kasaysayan ng medikal na kalagayan, at makipag-ugnayan sa treating surgeon tungkol sa pattern ng fracture (waist vs proximal pole), kung ang fracture ay acute o nonunion, kung gumamit ng bone graft, ang katatagan ng fixation, at ang plano para sa imaging milestone sa pagpapatunay ng union. Sinusunod ng hand therapist ang plano para sa indibidwal na fracture at fixation. Ang mga oras sa ibaba ay karaniwang gabay para sa isang matatag, screw-fixed na acute na fracture sa waist; mas maingat na pag-unlad ang inirerekomenda para sa mga proximal-pole, nonunion, at bone-grafted na fixations.

Yugto I - protektadang maagang paggalaw (linggo 0 hanggang 2)

Ang unang ilang linggo ay nagpoprotekta sa sugat at sa pagkaka-fixate habang pinapanatiling gumagalaw ang kamay. Ang pulso ay nakapahinga sa isang splint o maikling cast; ang mga daliri, hinlalaki, at forearms ay malayang gumagalaw mula sa unang araw. Ang pagsusuri sa sugat ay karaniwang naganap sa loob ng dalawang linggo, kung kailan nagsisimula ang pormal na terapiya.

Para sa iyong hand therapist:

Edukasyon at mga paalala - I-immobilize sa isang wrist splint o maikling cast ayon sa utos ng doktor; panatilihing tuyo; tanggalin lamang kung pinapayagan - Buong, agad na aktibong finger, thumb, elbow at shoulder ROM upang maiwasan ang stiffness - Walang pagkupot, pagbuhat, pagtindig o pagtulak sa pamamagitan ng pulso - Iwasan ang pinilit o end-range wrist extension

Pamamahala - Sugat: mga surgical dressing ayon sa utos; monitor para sa impeksyon; pagsusuri sa sugat ~2 linggo - Oedema: elevation, gentle hand pump, ice kung kinakailangan - Mga ehersisyo: aktibong finger/thumb composite flexion-extension; thumb opposition; gentle forearm pronation-supination; shoulder at elbow ROM

Mga pamantayan upang makapagpatuloy - Nagsara/nagpapagaling na sugat; umuunlad na sakit; clearance ng doktor upang magsimula ang wrist motion

Yugong II - protektadong mobilisasyon ng pulso (linggo 2 hanggang 8, nakabase sa pagkakabuon)

Mula sa humigit-kumulang dalawang linggo (para sa matatag, screw-fixed na acute waist fracture), ipinakilala ang banayad na aktibong galaw ng pulso sa loob ng komportableng saklaw na walang sakit sa ilalim ng proteksyon ng screw. Unahan-unahan ang pagpapalawak ng saklaw; ang pagpapalawak sa dulo ng saklaw (end-range extension) at anumang pagdadala ng bigat ay nananatiling ipinagbabawal. Ang mga fixation na may proximal-pole, nonunion, at bone-grafted ay pinapanatili sa protektadong immobilisasyon nang mas matagal at ginagalaw nang huli, sa gabay ng doktor.

Para sa iyong hand therapist:

Pagsusuri - Aktibong ROM ng pulso, sakit, pamamaga; pagsusuri sa sugat/peklat; pakikipag-ugnayan sa doktor tungkol sa imaging at kalagayan ng pagkakabuon

Edukasyon at mga paalala - Simulan ang banayad na aktibong pagtukol-pagbuka ng pulso (flexion-extension) at radial-ulnar deviation sa loob ng saklaw na walang sakit; unahan-unahang palawakin ang saklaw - Iwasan ang pagpapalawak sa dulo ng saklaw/pinipilit na pagtukol ng pulso at iwasan ang pagdadala ng bigat - Walang pagsasanay ng pagkapit, walang pagdadala ng bigat, walang resisted work hanggang sa kumpirmahin ang pagkakabuon - Patuloy na bukas-bukas ang mga daliri at forearms; simulan ang pamamahala ng peklat kapag gumaling na

Pamamahala - Mga ehersisyo: aktibo at active-assisted na ROM ng pulso sa loob ng komportableng limitasyon; patuloy na ROM ng mga daliri/hintuturo/forearms; pamamahala ng edema at peklat - Maaaring gamitin ang splint sa pagitan ng mga ehersisyo sa unang bahagi ng yugong na ito kung inirerekomenda; ang pagbaba ng immobilisasyon ay direktado ng doktor

Mga pamantayan para sa pag-unlad - Radiographic (karaniwang kumpirmado ng CT) pagkakabuon na kumpirmado ng doktor; komportable at kontroladong ROM ng pulso; minimong sakit. Lahat ng pamantayan ay kinakailangan bago simulan ang anumang pagsasanay ng lakas.

Yug III - Pagpapalakas at pagbabalik (pagkatapos ng kumpirmadong pagkakaisa)

Kapag kumpirmado ng doktor na ang fracture ay nagkakaisa na (karaniwan sa loob ng 8 hanggang 12 linggo para sa acute waist fracture, at mas maaga para sa proximal-pole fractures at nonunions), magsisimula ang pagpapalakas at unti-unting dadagdagan: simulan sa grip at putty work, pagkatapos ay progressive resisted wrist at forearm strengthening, at huli ay loaded at sport-specific work. Ang pagbabalik sa contact, collision, at load-bearing sport ay batay sa mga kriterya at kondisyong kumpirmadong pagkakaisa, karaniwan ay hindi bago ang tatlong hanggang apat na buwan, at madalas na mas maaga para sa mga high-risk fractures.

Para sa iyong hand therapist:

Pagsusuri - Grip at pinch strength kumpara sa kabilang bahagi; wrist ROM; tugon ng sakit/pamamaga sa pag-load; functional at sport-/work-specific testing kung kinakailangan

Edukasyon at mga paalala - Simulan ang grip at putty strengthening lamang pagkatapos ng kumpirmadong pagkakaisa ng doktor; unti-unting dagdagan ang load - Magdagdag ng progressive resisted wrist at forearm strengthening; pagkatapos ay graded loaded at closed-chain work - Ang pagbabalik sa contact/collision/load-bearing sport ay batay sa kumpirmadong pagkakaisa at mga kriterya, karaniwan ay hindi bago ang ~3-4 buwan at mas maaga para sa proximal-pole/nonunion; maaaring gamitin ang protektibong splint o cast para sa maagang supervised return sa mga atleta sa direksyon ng doktor

Pamamahala - Mga ehersisyo: graded grip/putty → resisted wrist at forearm strengthening (band → light weights) → loaded at sport-specific drills; patuloy na anumang residual mobility work - Isalang-alang ang discharge kapag ang strength ay halos symmetrical at naabot ang angkop na pagbabalik ng function - I-refer pabalik sa treating surgeon kung ang recovery ay huminto, tumatagal ang sakit, o may pagdududa sa pagkakaisa (isalang-alang ang delayed union/nonunion o AVN)

Mga kriterya para sa pagbabalik sa sport - Kumpirmadong pagkakaisa ng doktor; buong painless ROM; halos symmetrical na grip strength; pain-free sport-specific loading at kontrol

Pagbabalik sa trabaho at gawain

Ang magaan na paggamit ng kamay sa pang-araw-araw na gawain (pagkain, pagsulat, paghuhubog, magaan na sariling pag-aalaga) ay inirerekomenda mula sa simula, hangga't komportable, basta't hindi ito kasama ang pagkapit, pag-angat o pagpilit sa pulso. Ang opisina at iba pang magaan, hindi-manwal na trabaho ay madalas na posible nang maaga, minsan ay sa loob ng unang dalawang linggo sa mga binagong tungkulin; ang mas mabigat na manwal na trabaho na naglo-load sa pulso ay hinihintay hanggang sa mag-union ang fracture, at dahan-dahang binubuo pagkatapos.

Dahil kailangan mong makontrol ang sasakyan nang ligtas, huwag magmaneho habang nasa cast o splint ka na nagpipigil sa ligtas na pagkontrol ng manibela, o habang hindi ligtas ang pulso na magmaneho at magkapit. Magbabalik sa pagmamaneho kapag wala ka na sa restrictive cast at kayang-kaya at ligtas mong kontrolin ang sasakyan, ayon sa pagpapatunay sa iyong review. Magplano para sa tulong sa transportasyon sa mga unang linggo.

Ang paglo-load sa pamamagitan ng pulso (matinding pagkapit, pag-angat, pagtulak, pagpindot at paghila) ay hinihintay hanggang sa kumpirmahin ng iyong surgeon na nag-union na ang buto, at dahan-dahang binubuo pagkatapos. Ang pagbabalik sa contact, collision at load-bearing sport ay nakadepende sa union, karaniwan ay hindi bago ang tatlong hanggang apat na buwan, at madalas na mas maaga para sa mga proximal-pole fractures at nonunions. Ito ay batay sa kumpirmadong paggaling plus pagbawi ng buong walang-sakit na galaw at sapat, symmetrical na lakas ng pagkapit, pinahahalagahan ni Dr. Hirpara at ng iyong hand therapist, hindi lamang sa kalendaryo.

Pagkatapos ng iyong protocol

Ang protocol na ito ay nagtatrabaho kasama ng pangkalahatang payo para sa paggaling ng klinika: tingnan ang pamamahala ng sakit pagkatapos ng operasyon, pag-aalaga sa sugat, at pamamahala ng peklat. Ang naka-ayos na plano sa itaas ay sumasalamin sa mga inilathalang gabay sa rehabilitasyon pagkatapos ng pag-ayos ng scaphoid, at ang iyong patuloy na paggaling ay pinamumunuan nang indibidwal ni Dr. Hirpara at ng iyong hand therapist ayon sa iyong fracture, iyong fixation, at kung paano gumagaling ang iyong pulso.

Scaphoid Fixation — Fracture Fixation Outcomes & Post-operative Rehabilitation (Headless Compression Screw ± Bone Graft)

Topic scope: post-operative rehabilitation after internal fixation of a scaphoid fracture with a buried headless compression screw — percutaneous or open, for an acute fracture or for a nonunion (the latter usually with bone graft, e.g. distal-radius cancellous or vascularised graft). This is a fixation of a slow-healing bone, not a soft-tissue repair: rehabilitation is paced by bone union rather than by tendon/ligament healing windows, and the central tension is between the early-motion advantage that rigid screw fixation buys and the scaphoid's biological tendency to heal slowly and, when neglected, to fail to unite.

Defining principle of the rehab here: the scaphoid has a tenuous retrograde blood supply (it fills from distal to proximal), so it heals slowly and the proximal pole is at risk of delayed union, nonunion and avascular necrosis. A headless compression screw compresses and stabilises the fracture, which is what permits earlier protected wrist motion than a cast alone and earlier return to work/sport in suitable fractures. But the construct does not change the bone's biology: grip, loading and contact sport remain union-gated — held back until the surgeon confirms healing, commonly on CT. Progression is therefore fixation- and fracture-dependent: a stable, screw-fixed acute waist fracture mobilises early; a proximal-pole fracture, a nonunion, or a bone-grafted case is treated more cautiously. The hand therapist follows the plan for the specific fracture and fixation.

A. FIXATION OUTCOMES (acute fixation, and nonunion fixation with graft)

Headless compression screw fixation is a reliable operation with high union rates; the principal debates are who should be fixed acutely (vs cast) and how aggressively to mobilise, not whether the screw works.

  • Headless compression screws give high union rates and earlier mobilisation. Internal fixation of scaphoid fractures with headless compression screws achieves high union in both non-displaced and displaced fractures, with the added benefits of earlier mobilisation and earlier return to work and sport compared with cast treatment [Fowler & Ilyas, Hand Clin 2010; Fowler & Hughes, Clin Sports Med 2015]. Moderate (narrative/technique reviews + cohort).
  • Percutaneous screw fixation unites faster than cast for acute waist fractures. A randomised trial of 60 acute scaphoid-waist fractures found percutaneous Acutrak screw fixation reached union significantly faster than cast immobilisation (~9.2 vs ~13.9 weeks), with a trend to fewer nonunions [Bond et al., J Bone Joint Surg Br 2008]. Moderate–strong (RCT, single-centre).
  • But surgery vs cast for minimally displaced waist fractures gives equivalent long-term function at the cost of more complications. The pragmatic multicentre SWIFFT RCT (bicortical, ≤2 mm displaced waist fractures) found no meaningful difference in wrist function between early surgical fixation and cast immobilisation (with fixation reserved for the cast fractures that failed to unite), while surgery carried more complications. Systematic reviews/meta-analyses concur: surgery favours union but raises complication risk, with ROM, grip and arthritis rates not significantly different [Dias et al., SWIFFT, Lancet 2020; Alshryda et al., The Surgeon 2012; Modi et al., Injury 2009; Rhemrev et al., Injury 2009]. Strong (RCT + SRs).
  • Nonunion fixation with bone graft restores union in most cases but heals slower. Scaphoid nonunions treated with screw fixation and bone grafting (non-vascularised distal-radius, vascularised distal-radius, or two-screw constructs) achieve union in the large majority, with proximal-pole and avascular cases the hardest. Acute fixation unites ~100% vs chronic/nonunion ~87% in pooled experience [Garcia et al., J Hand Surg Am 2014; Ribak et al., Int Orthop 2009; Kim et al., Orthop Traumatol Surg Res 2018; Wu et al., Bone Joint J 2022; Simonian & Trumble, JAAOS 1994]. Moderate (cohort/SR).
  • The elite/competitive athlete is a distinct decision. Early screw fixation is often favoured in athletes to compress the fracture, shorten immobilisation and enable earlier (often splinted) return to play, accepting the surgical risk for the time advantage [Belsky et al., Hand Clin 2012; Fowler & Hughes, Clin Sports Med 2015]. Moderate (expert/cohort).

B. REHABILITATION / THERAPY EVIDENCE

The rehab questions are (1) how soon to mobilise the wrist after rigid fixation, (2) when to permit loading/grip, and (3) when to confirm union and clear sport. The evidence supports early protected motion under the screw but keeps strengthening and sport union-gated, with proximal-pole/nonunion cases handled more conservatively.

  • Rigid screw fixation permits earlier protected wrist motion than cast-alone. The mechanical rationale is that compression across the fracture confers stability, allowing the wrist to begin gentle motion while the bone unites; reported acute-fixation pathways start gentle mobilisation early with a ~2-week wound/therapy review and ~6-week radiographic check [Fowler & Ilyas, Hand Clin 2010; Fowler & Hughes, Clin Sports Med 2015]. Moderate (technique/expert).
  • Union is the gate for loading — and it is slow and imaging-confirmed. Reported time to union ranges ~7–16 weeks depending on healing criteria, fracture site and population (athletes vs general), and CT is frequently used to confirm union before clearing loading and sport because plain films overestimate healing [Ecker, Hand Clin 2017 (scaphoid union); Fowler & Hughes, Clin Sports Med 2015]. Moderate.
  • Proximal-pole fractures, nonunions and grafted cases progress more slowly. The proximal pole's poor vascularity means later union and a more cautious return; arthroscopic and open grafting series for nonunion report union but over longer timeframes [Wu et al., Bone Joint J 2022; Shih et al., J Orthop Surg Res 2023; Garcia et al., J Hand Surg Am 2014]. Moderate (cohort).
  • Percutaneous/antegrade technique is a safe route that supports the early-motion pathway. The percutaneous antegrade approach minimises soft-tissue insult and supports the earlier-mobilisation rationale in suitable fractures [Weinberg et al., Injury 2009]. Moderate (cohort).

Recovery trajectory (expected, evidence-anchored)

Phase Window Restraint Hand use / therapy focus Strength / load Notes
I — Protected early motion Week 0–2 Wrist splint/short cast; no wrist loading Immediate active finger/thumb/elbow/shoulder ROM; oedema control; wound review ~2 wk None through the wrist Hand kept supple; scaphoid undisturbed
II — Protected wrist mobilisation Week 2–8 (union-gated) No grip/loading; avoid end-range/forced extension Gentle active wrist flexion-extension and deviation in pain-free range; gradual progression; forearm rotation; scar massage once healed No resisted/grip work For stable, screw-fixed acute waist fractures. Proximal-pole/nonunion/grafted: immobilise longer, mobilise later
III — Strengthening & return After confirmed union (commonly ~8–12 wk acute waist; later for proximal pole/nonunion) Restrictions lifted on union Grip/putty → progressive resisted wrist/forearm → loaded & sport-specific Graded to symmetrical grip Contact/load sport union-gated, typically not before ~3–4 months, later for high-risk fractures; CT often confirms union

(Phase windows are typical guides for a stable screw-fixed acute waist fracture, not trial-derived deadlines; proximal-pole, nonunion and bone-grafted fixations are paced more conservatively by the surgeon and hand therapist.)

C. KEY CONTROVERSIES / EVIDENCE QUALITY

  1. Screw fixation vs cast for the acute minimally displaced waist fracture. Fixation unites faster (Bond RCT: ~9 vs ~14 weeks) and returns athletes/workers sooner, but SWIFFT and meta-analyses show equivalent long-term wrist function with more complications from surgery for minimally displaced waist fractures. The defensible position is selective fixation (displacement, proximal pole, high-demand athlete/worker, patient preference) rather than routine surgery for every undisplaced waist fracture [Dias SWIFFT Lancet 2020; Bond JBJS Br 2008; Alshryda Surgeon 2012; Modi/Rhemrev Injury 2009]. Strong evidence of functional equivalence; moderate on the complication trade-off.
  2. Early motion vs continued immobilisation after fixation. Rigid compression is the rationale for earlier protected wrist motion than cast-alone, and reported pathways mobilise early — but there is no high-certainty trial defining the optimal mobilisation schedule, so timing is surgeon/ therapist protocol and fracture-dependent. Weak–moderate (mechanism strong, scheduling consensus).
  3. When is it united — and what confirms it. Time to union is wide (~7–16 weeks) and plain radiographs overestimate healing; CT is commonly used to confirm union before clearing loading and sport, which is the true gate for progression [Ecker Hand Clin 2017]. Moderate.
  4. Return-to-sport timing. Union-gated and fracture-dependent; competitive athletes may return earlier in a protective splint/cast at surgeon discretion, accepting risk, whereas proximal-pole and nonunion cases return later. Reported real-world return is typically months, not weeks [Belsky Hand Clin 2012; Fowler & Hughes Clin Sports Med 2015]. Moderate (expert/cohort).
  5. Nonunion and proximal-pole biology. The retrograde blood supply drives delayed union, nonunion and AVN risk; grafting (cancellous, corticocancellous, or vascularised) addresses biology but lengthens the timeline. Persistent pain or doubtful union warrants reassessment rather than more loading [Garcia JHS Am 2014; Ribak Int Orthop 2009; Kim OTSR 2018; Wu BJJ 2022; Simonian & Trumble JAAOS 1994]. Moderate.

D. EVIDENCE STRENGTH FLAGS (summary)

  • STRONG (RCT / SR): equivalent long-term wrist function from surgery vs cast for minimally displaced acute waist fractures, with more complications from surgery (SWIFFT + meta-analyses); faster union with percutaneous screw fixation than cast (Bond RCT, ~9 vs ~14 weeks).
  • MODERATE: high union rates and earlier mobilisation/return with headless compression screws; nonunion union rates with screw + bone graft (acute ~100% vs chronic ~87%); wide ~7–16-week union window and CT confirmation of union; athlete-specific early/splinted return.
  • WEAK / CONSENSUS: the specific early protected-motion, union-gated phase schedule (mechanistically rationalised by rigid compression; exact timings are surgeon/hand-therapist protocol and fracture-dependent, not trial-derived); precise return-to-sport months.

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and conditions that creators and other rights holders may use to share original works of authorship and other material subject to copyright and certain other rights specified in the public license below. The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses.

Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC- licensed material, or material used under an exception or limitation to copyright. More considerations for licensors: wiki.creativecommons.org/Considerations_for_licensors

Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

Creative Commons Attribution-NonCommercial 4.0 International Public License

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. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

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.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public 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:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

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.
