how do you check the median nerve
okay sign
how do you check the radial nerve
thumbs up
how do you check the ulnar nerve
restroom sign
what is the carpal tunnel syndrome
entrapment of the median nerve in the carpal tunnel
what are motor impairments of carpal tunnel syndrome
weakness and atrophy of the thenar muscles
what passes thru the carpal tunnel
flexor digitorum superficial
flexor digitorum profundus
flexor pollicis longus
median nerve
when you get surgery for carpal tunnel syndrome what are you releasing
the transverse carpal ligament
the transverse carpal ligament does not
make bowstring
what is median nerve palsy
impaired sensation among palmer aspect of radial half of hand
if you have proximal median nerve palsy then you have loss of
anterior compartment of forearm (except FCU and medial half of FDP)
is you have distal median nerve palsy then there is loss of
thenar muscles and lateral 2 lumbricals
what is ape hand
atrophy of thenar muscles
where dies the thumb rest in ape hand
in addiction
ape hand is described in
resting position
what is the hand of benediction
extension of digits 1-3 when actively making a fist
what is radial nerve palsy
impaired sensation along dorsal aspect of thumb and radial half of the hand
radial nerve palsy causes a loss of muscles in
posterior arm and forearm with a decreased grip strength
what is wrist drop
wrist rests in flexion
what does wrist drop limit
the ability to extend teh wrist and fingers
what is ulnar nerve palsy
impaired sensation along the palmar aspect of digit 5 and ulnar half of digit 4
proximal ulnar nerve palsy leads to loss of
FCU and medial half of FDP
distal ulnar nerve palsy leads to loss of
intrinsics , adductor pollicis , hypothenar muscles, and medial 2 lumbricals
what is Claw hand
MCO joints are hyperextended and Ip joins are flexed
claw hand leads to
loss of intrinsic muscles
