New cards

what are the side effects of a sensory nerve injury

sensory and motor deficits
loss of lateral key pinch
it will effect the Interossei muscles, adductor policis, lumbricals of 4th and 5th digit

New cards

what is the flexor retinaculum

it holds the tendons close to wrist, prevents carpal bones from spreading

New cards

what is the transverse carpal ligament

arches over carpal bones

prevents tendons from pulling away ( bowstringing) from carpals

New cards

what is carpal tunnel syndrome

when there’s increased pressure in the carpal tunnel
decreases blood flow to small arteries that supply median nerve

New cards

what is palmar aponeurosis, and what do synovial sheaths do

thick layer of facia over your palm
maintains positions for flexor tendons

(synovial sheaths lubricate tendons and reduce friction )

New cards

dupuytren contracture

abnormal thickening of palmar aponeurosis

causing contracture of small and ring fingers
(surgical procedure »fasciotomy)

New cards

what is the extensor retinaculum

holds tendons to wrist

(splits tendons into 6 compartments)

New cards

what is De Quervains Tenosynovitis

“texting thumb”

affecting the tendons on the thumb side of your wrist.

Caused by repetitive gripping, typing, or lifting (like carrying a baby), common in new mothers
