• repair of structures not primarily repaired
• promote healing/enhance function e.g. malunion, nonunion, tenolysis
• enhance function - arthrodesis, bone lengthening, tendon transfers etc.

• Replantation - secondary surgery
  • Rate of secondary surgery in replantation is high, and may be multiple
  • In replantation - try to do everything primarily – hard to comeback to do secondary recon
  • Timing - 3 months - supple skin – can be delayed by wound problems; junction of native and flap skin is issue for tendon grafts.
  • Flexion more important than extension
  • Jupiter - good results with tenolysis in replantation 72 degrees to 130 degrees; Yu 119-159

25 Female MVA Initial treatment at a different hospital - external fixation and debridement; came infected - overall goal - preserve upper limb and maximise function of hand and upper limb

D0: debridement and external fixation –> infection D7-30+: multiple debridements, shortening, fixation with plates and screws

Secondary procedures - 7 months: Restore passive motion of forearm and digits before tendon transfer –> take down of radioulnar synostosis, MCPJ captulectomy, removal of radial plates - 9 months: tendon transfers - IF FDS to FPL, MF FDS to IF & MF FDP, RF FDS to RF & SF FDP - complicated by recurrence of HO – 11 months: re-excision of HO & release of contracture; FFMT gracilis for finger extension - 19 months: MF, RF, SF captulectomy, arthrolysis, scar revision - outstanding issues: loss of supination

• Bradway and Malone
• Limited information - UE only < 10% of all amputations
• psychiatric intervention needed only for minority
• Stages
  • preop - anticipation/ grief
  • immediate postop - early acceptance not necessarily good, more optimism in life threatening ijuries
  • with rehabilitation - denial
  • at home - critical phase; learn to adapt or stuck in denial
• Guidelines in managing
  • start pre-op
  • Amputation as a “reconstructive” procedure

• Functional outcome following traumatic upper limb amputation and prosthetic limb fitting
  • early fitting better results
  • compare with chevrier1956: lower usage rate at follow up ? because of long interval between diagnosis and referral; but group also different (not just trauma)

Pollicization

• used less in microsurgical age
  • may be best option
    • nearer to CMCJ
  • disadvantages
    • sensation - still IF
    • loss of digit

• IF by far most common - but can use other digits
  • consider if injured other digits

Binhammer and Lister's article is quite good

• tendon transfer for opposition - FDS RF
• Fixation
• shortening - distally or proximally – ? length
• check circulation

Ivan Matev's chapter in Foucher's book:

• 50% easy, 80% possible, sometimes 100% in young
• young - slower (1mm /d) but more lengthening
• older - more likely bone graft (45-60 days) if no good callus - in situ
• problems - union, angulation, infection, MCPJ flexion
• need good skin first
• can paint nail
• make sure CMCJ is good, skin at tip is good first, sometimes need to deepen/widen web

• flap - groin/abdominal vs radial forearm
  • size: 6-7 cm
  • 1-2 cm shortening
  • avoid circular seam - either oval or zig-zag
  • seam in palmar side of “thumb”

• bone - iliac crest, tibia, radius
  • make thumb slightly shorter than other side
  • bone fixation –> wedge into MC/P1

• neurovascular island flap - ulnar side of MF
  • ulnar side of RF
  • make sure it is big enough

• nerve repair +/-

• Staging - 3 vs 2 vs 1 stage

• sensory recovery
• flap necrosis
• bone graft resorption - related to flap

• see giladi2016
• MSK Trauma big burden – especially developing countries
  • need for outcome measures – move towards PROMs
• PROMs context specific – different countries and cultures –> different
• disability vs impairment – measures don't map well
• different PROMs don't correlate well too
• individualized treatment - need shared decision making
