Hand incisions
Normal alignment and rotational
deformity
Mallet deformity
Flexor tendon injury
Zones for tendon repair
Flexor Tendon Anatomy
Methods of tendon repair
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
Occupation
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
Children
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
Splintage
rehabilitation
Gracillis free flap
Thoracodorsal artery perforator
flap
Radial forearm free flap
Hand Infection
Bacterial
Viral
Fungal
Protozoal
64% grow multiple
organisms
Hand Infection:
anatomical compartments
Nail fold (paronychia)
Pulp space
Tendon sheath
Web space
Deep palmar space
Septic arthritis
Infection: history
Time lapse
cellulitis
tendon sheath
web space
deep palm
paronychia
pulp space
septic arthritis
24 hours
48 hours
days
4-5 days
<2 weeks
Web space infection
Deep palmar infection
Infection: tendon sheath
Finger in slight flexion
Uniformly red and
swollen
Intense pain on
attempted extension
Tenderness along line of
sheath
Drainage of tendon sheath
Drainage of mid-palmar space
Infection: septic arthritis
Usually secondary to human bite
Swelling out of proportion to inflammation
Restricted motion
Instability
Discharging sinus
X-ray changes
Paronychia
Pulp space infection
