Profundus Avulsion
Open fractures - classification

Type   I      tidy wound < 1cm
Type   II     tidy wound 1-2 cm
Type   IIIA   >2cm; soiled
Type   IIIB   IIIA + periosteal stripping
Type   IIIC   neurovascular damage
Severe hand injury survey

Blood supply
Stable skeleton
Viable skin cover
Basic function
Serious hand trauma
-after debridement

Longitudinal/ extensile exposures
Compartment decompression
Skeletal alignment/ fixation
Musculo-tendon repair
Vessel repair/ graft
Nerve repair
Replantation - indications

All amputations at the level of the arm, forearm,
 carpus and metacarpus
All amputations of thumb prox to mid distal phalanx
In multiple digits replant as many as possible
Most digits amputated distal to prox phalanx
Think about avulsed digits and crushed distal parts
Hand Replantation

7 months off work
50% get only protective sensation
50% range of movement
60% need > 2 operations
Medical cost 5-15 times amputation
Nerve Repair

Partial nerve
Full nerve
Regrow at 1mm per day
Hand Infection

64% grow multiple
