Flashcards in Hand/Wrist Deck (15):
1

Colles Fracture (dinner fork)

transverse fracture of the distal radial metaphysics with anterior displacement

2

Madelung Deformity

developmental abnormality of the wrist leading to palmar and ulnar wrist subluxation

3

Finkelstein's test

fingers around thumb and ulnar deviation.
evidence of tenosynovitis of extensors

4

Allens test

used to determine the function of the radial and ulnar arteries supplying the hand
- squeeze hand and then release like 5 times then apply pressure to radial and ulnar arteries. if one is broke it won't become red

5

kienbocks disease

loss of blood supply to the lunate bone

6

Mallet finger

blow from an object that strikes the tip of the finger, jamming and avulsing the extensor tendon from its insertion, along with a piece of bone

7

boutineere deformity

rupture of the extensor tendon dorsal to the middle phalanx. trauma occurs to the tip of the finger which forces the DIP joint into extension

8

Jersey finger

flexor digitorum profundus from its insertion on the distal phalanx, usually ring fingers.
**inability to flex the finger

9

Dupuytren's contractuer

nodules develop in the palmar aponeurosis that limit finger extension

10

swan neck

distal tear of the solar plate from the middle phalanx
severe hyperextension of PIP

11

Bennets fracture

occurs in the first metacarpal just distal to eh CMC joint of the thumb as a result of an axial and abductional loading

12

Boxers fracture

metacarpal fracture
direct axial force or a compressive force

13

drop wrist

palsy of the radial nerve

14

claw hand

compression of the median and ulnar nerves

15

ape hand

results from palsy of the median nerve
