suprachondylar area
extensors and supinators lie in which compartment?
posterior
lateral epicondylitis is caused by repetitive use of […] muscles
extensor
pain over lateral epicondyle that radiates down posterior surface of the arm
lateral epicondylitis
pain is felt with opening doors or lifting a glass

medial epicondylitis
pain is felt when flexing the wrist or squeezing a ball
medial epicondylitis
avulsion of extensor digitorum tendon

grip
palmaris longus attaches distally to
palmar aponeurosis
if there was a puncture would to the 5th digit synovial sheath, where could the infection spread?
thumb, hand
even through carpal tunnel and up forearm
if there was a puncture wound to the 3rd digit synovial sheath, where could the infection spread?
nowhere, stays local
**2,3,4 have individual sheaths
caused by disparity in size of the flexor tendons vs the retinacular pulley system
trigger finger (stenosing flexor tenosynovitis)
