Athletic Injuries: Forearm/Wrist/Hand Flashcards
Tinel’s sign
tapping over transverse carpal lig of the carpal tunnel indicates carpal tunnel syndrome of median nerve
Phalen’s test
prayer and reverse prayer pose indicates carpal tunnel syndrome
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
Lunotriquetral Ballotment Test
stabilize the lunate and slide the triquetrum anteriorly and posteriorly to look for laxity determines dislocation of the lunate
Allen’s test
determine function of the radial and ulnar arteries pt has to squeeze and release hand four times
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
Wrist tenosynovitis
occurs to the extensor carpi radialis brevis or longus, caused by repetitive wrist accelerations and decelerations
Wrist Tendinits
of the flexor carpi radialis and flexor ulnaris common in wrist flexion activities
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
Carpal tunnel syndrome
anterorior aspect of the wrist, results from inflammation of the tendons and synovial sheaths that compress the median nerve
De quervain’s syndrome
stenosing tenosynovitis in the thumb tendons= extensor pollicis vrevis and abductor pollicis longus
Lunate dislocation
most commonly dislocated carpal bone, occurs from forceful hyperextension often from FOOSH MOI
Kienbock’s disease
loss of blood supply to the lunate bone resulting in kosteonecrosis
Scaphoid fracture
most frequently fractured carpal bone, FOOSH mechanism, mistaken for sever sprain can fail to heal without proper splintin
Hamate fracture
FOOSH
Wrist Ganglion (cyst)`
synovial cyst considered to be a joint herniation appears slowly and contains clear mucinous fluid
Trigger finger
tenosynovitis most commonly effects extensor pollicis longus, extensor pollicis brevis, and abductor pollicis longus
Mallet finger (Extensor tendon avulsion)
caused from blow that strikes tip of the finger avulsing the extensor tendon
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
Jersey Finger (flexor digitorum profundus rupture)
rupture of flexor digitorum profundus tendon often occur to ring finger
Dupuytren’s Contracture
nodules develop in palmar aponeurosis that limit finger extension and cause a flexion deformity
Gamekeeper’s thumb
sprain of the UCL of the MCP joinjt of the thumb MOI forceful abduction of proximal phalanx
Swan Neck deformity
PIP joint injured from severe hyperextension force resulting in swan neck deformity
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
