carpal tunnel syndrome is compression of the
median n in the carpal tunnel
what are the symptoms of carpal tunnel syndrome
pain
numbness
tingling in the thumb, index, and middle finger - and thumb side of ring finger
what muscles are affected in carpal tunnel syndrome
thenar eminence muscles →
abductor pollicis brevis
flexor pollicis brevis
opponens pollicis
ABOF of ABOF
the anterior muscles of the forearm are divided into
intermediate
middle
superficialis
deep/profundus
which layer of of forearm muscles is the insertion for the distal phalanges
deep (profundus)
which layer of forearm muscles is the insertion for the middle phalanges
intermediate/middle/superficialis
what is the camper’s chiasm
the split that the profunda tendons go through
a supracondylar fracture can cause ischemia to the
anterior (flexor) compartment of the forearm
when would you see a “fat pad” sign on xray
radial fx
what is nursemaid’s elbow
subluxation of the radial head from the anular ligament
what is epicondylitis
inflammation of the extensor carpi radialis brevis
in compartment syndrome, you would see the 6 p’s with
passive extension of the compartment
the brachial artery is palpable along the length of the
anterior compartment of the forearm
which artery is used to measure blood pressure
brachial artery
at what landmark does the axillary vein become the basilic vein
clavicopectoral fossa
what 2 structures form the cubital fossa
brachioradialis
pronator teres
what are the contents of the cubital fossa
tendon and aponeurosis of biceps brachii
brachial artery
median nerve
median cubital vein
what is monteggia’s fx
fracture of proximal third of ulna and anterior dislocation of the radius at the elbow
what is galleazzi’s fracture
fracture of distal third of radius and sublucation of the distal head of the ulna
what is colle’s fracture
fracture if distal radius w. dorsal displacement of distal fragments
what is the TFCC
triangular fibrocartilage complex → articular disc btw distal radius, ulna, and wrist joint
what is the fxn and clinical significance of the TFCC
it stabilizes the radioulnar joint → tears can be painful and troublesome
the hand articulates primarily with the
radius
