Flashcards in Athletic Injuries: Forearm/Wrist/Hand Deck (24):
1

Tinel's sign

tapping over transverse carpal lig of the carpal tunnel indicates carpal tunnel syndrome of median nerve

2

Phalen's test

prayer and reverse prayer pose indicates carpal tunnel syndrome

3

Valgus/Varus glide stress tests for wrist

applying valgus and varus stress as well as anterior and posterior can determine the presence of a sprain in one of the ligaments that connect the carpal bones

4

Lunotriquetral Ballotment Test

stabilize the lunate and slide the triquetrum anteriorly and posteriorly to look for laxity determines dislocation of the lunate

5

Allen's test

determine function of the radial and ulnar arteries pt has to squeeze and release hand four times

6

TFCC injury Triangular Fibrocartilage Complex

TFCC separates radiocarpal and inferior radioulnar jx's, prone to cartilage tears that can result in clicking or catching often torque injury

7

Wrist tenosynovitis

occurs to the extensor carpi radialis brevis or longus, caused by repetitive wrist accelerations and decelerations

8

Wrist Tendinits

of the flexor carpi radialis and flexor ulnaris common in wrist flexion activities

9

Nerve Compression/Entrapment

two most common are of the median nerve in the carpal tunnel and the ulnar nerve in the tunnel of Guyon b't pisiform and hook of the hamate

10

Carpal tunnel syndrome

anterorior aspect of the wrist, results from inflammation of the tendons and synovial sheaths that compress the median nerve

11

De quervain's syndrome

stenosing tenosynovitis in the thumb tendons= extensor pollicis vrevis and abductor pollicis longus

12

Lunate dislocation

most commonly dislocated carpal bone, occurs from forceful hyperextension often from FOOSH MOI

13

Kienbock's disease

loss of blood supply to the lunate bone resulting in kosteonecrosis

14

Scaphoid fracture

most frequently fractured carpal bone, FOOSH mechanism, mistaken for sever sprain can fail to heal without proper splintin

15

Hamate fracture

FOOSH

16

Wrist Ganglion (cyst)`

synovial cyst considered to be a joint herniation appears slowly and contains clear mucinous fluid

17

Trigger finger

tenosynovitis most commonly effects extensor pollicis longus, extensor pollicis brevis, and abductor pollicis longus

18

Mallet finger (Extensor tendon avulsion)

caused from blow that strikes tip of the finger avulsing the extensor tendon

19

Boutonniere deformity

rupture of the extensor tendon dorsal to the middle phalanxe DIp joint in extension and PIP joint in Flexion, splinting of PiP joint in extension

20

Jersey Finger (flexor digitorum profundus rupture)

rupture of flexor digitorum profundus tendon often occur to ring finger

21

Dupuytren's Contracture

nodules develop in palmar aponeurosis that limit finger extension and cause a flexion deformity

22

Gamekeeper's thumb

sprain of the UCL of the MCP joinjt of the thumb MOI forceful abduction of proximal phalanx

23

Swan Neck deformity

PIP joint injured from severe hyperextension force resulting in swan neck deformity

24

Bennett's fracture

occurs in the first metacarpal just distal to the carpometacarpal joint of the thumb as a result of axial and abduction force to the thumb
