Wrist and hand Flashcards
what are the ideal ROM for flexion, extension, radial deviation, and ulnar deviation
flexion: 30-50
extension: 60
radial deviation: 20
ulanr deviation: 40
describe the functional position of the hand
wrist slightly hyperextended
2nd-5th slightly flexed
thumb opposition
what is the cause of de quervain’s tenosynovitis
repetitive thumb use with ulnar deviation and gripping
directly related to smartphone use
describe de quervain’s tenosynovitis
inflammation and likely thickening of extensor pollicis brevis and abductor pollicis longus tendons and sheath causing pain just proximal to anatomical “snuff box”
what are the symptoms of de quervain’s teno
decreased grip and pinch strength at thumb
what special test is used for de quervain’s tenosynovitis
finkelstein’s - minimal to no clinical support
what is the PT Rx for de quervain’s tenosynovitis
POLICED
reduced typing and dictate
tendinosis MET
tendon glide
thumb splint
are injections for de quervain’s tenosynovitis
injections are 73% successful
what is the extensor expansion ligament
small triangular-shaped aponeurosis of connective tissue
wide at base and narrow distally
what muscles attach on the extensor expansion ligament
extensor digitorum
lumbricals
interossei
what is mallet finger
tendon rupture/avulsion fracture of the extensor hood mechanism at DIP with trauma/disease
what is the rx for mallet finger
splinting and possible PT to help mobility after mobilization
what is a boutonniere deformity
rupture/stretch of extensor tendon at PIP with trauma/disease
results in PIP flexion with DIP extension
what is swan neck deformity
rupture of volar plate at PIP with trauma/disease
results in hyper extension at PIP and flexion and DIP
what is the rx for ruptured tendon
addressing consequences of immobilization and focused on tendon repair/remodeling
