Clinical Anatomy - Upper Limb Flashcards
cartilaginous extension of the glenoid cavity
labrum
movements at olecranon
flexion/extension
movements at RUJ
supination/pronation
area particularly susceptible to fracture in children
supracondylar region
what may be compromised in a fracture to the supracondylar region
median nerve and brachial artery
ligaments in elbow
medial and lateral collaterals, annular ligaments
Tennis elbow
lateral epicondylitis
occurs at common extensor origin
Golfer’s elbow
medial epicondylitis
occurs at common flexor origin
annular ligaments critical to prevent bowstringing
A2/4
annular ligaments which overlie MP/PIP/DIP
A1/3/5
pulley most commonly involved in trigger finger
A1
function of cruciate pulleys
prevent sheath collapse and expansion during digital motion
muscular supply of median nerve
flexors of the forearm LOAF muscles (lumbricals 1/2, opponens pollicis, abductor pollicis brevis, flexor pollicis brevis)
how to test muscular supply of median nerve
test abductor pollicis brevis
cutaneous sensation of median nerve
radial 3.5 digits
how to test cutaneous sensation of median nerve
test tip of index finger and base of thenar muscles
muscular supply of ulnar nerve
small intrinsic muscles of the hand
how to test muscular supply of ulnar nerve
test adductor digiti minimi, abductor indicis
cutaneous sensation of ulnar nerve
ulnar 1.5 digits
how to test cutaneous sensation of ulnar nerve
test dorsum and volar aspects of little finger
muscular supply of radial nerve
extensors of the forearm
how to test muscular supply of radial nerve
test extensor digitorum and extensor indicis
cutaneous sensation of radial nerve
variable portion of dorsum of hand
how to test cutaneous sensation of radial nerve
dorsum of 1st webspace
what is the brachial plexus
network of the ventral rami of the lower 4 cervical nerves and first thoracic nerve roots
subunits of brachial plexus
roots - trunks - divisions - cords - branches
cubital tunnel boundaries
arch formed by 2 heads of flexor carpi ulnaris muscle and arcuate ligament
cubital tunnel syndrome
ulnar nerve impingement
carpal tunnel boundaries
carpal bones and flexor retinaculum
carpal tunnel syndrome
median nerve impingement
function of palmar fascia
separates palmar muscle bellies and flexor tendons
