A 32 year old #Uber
driver had his index finger and long (middle) finger caught in a door. Sustained what is essentially a ring avulsion injury.
- the force needed for this injury is between 80-145 Newtons, by comparison to cut off a wedding band you need 1000N of force.
- lower overall survival for avulsed digits replantation (60%) than #fingerreplantation
in general (90%).
- lower survival for #avulsed
thumb (68%) than finger (78%) replantation.
- 70% get #coldintolerance
- if replant is needed, must repair >2 veins.
This particular would is treated with #I&D
of the wound, scrub w betadine brush, and pinning of #phalanxfractures
as needes. Also should end to end repair any FDS (and FDP) if possible.
