Compartment syndrome

4

Name four general types of hand injury?

Crush

Burn

Sharp

Degloving

5

What is degloving?

Avulsion of an extensive area of skin

6

What is a subungual haematoma?

Bleeding under the nail

7

What is the main symptom of subungual haematoma?

Pain

Due to pressure build-up

8

What eventually happens to the nail in subungual haematoma?

Falls off and grows back

9

levels of nailbed injury

higher number increases chance of amputation

10

how would you treat an unstable fracture?

k wires to stabilise 

mobility asap 

11

slide 16 - angulation fracture of thumb, stabilised

12

slide 17 - unstable, flexor tendons want to pull it downwards

stabilise - plates, screws or wires

13

why do totally immobilised fractures heal slower?

what should be encouraged?

lack of callus formation

micromobility

14

what may happen if an intraarticular fracture isnt fixed?

zone II is important - tendons adhere to one another within the sheathe, predicting course is difficult

19

FDP attaches to distal phalanx

FDS to middle and proximal

to demonstrate FDP function, hold PIP straight and flex finger

to demonstrate FDS function, hold all other fingers straight and flex finger

20

 how are tendons repaired? 

by suture and hand splinted to prevent re-rupture

21

dealing with severe mutilation

wash

remove clearly infected or necrotic tissue

assess vasculature

rest on slides
