compressive neuropathies Flashcards
1
Q
carpal tunnel syndrome risk factors
A
- idiopathic
- rheumatoid
- fractures (especially Colles)
- fluid retention
2
Q
what is the carpal tunnel
A
space between the wrist bones and flexor retinaculum that permits the passage of tendons and the median nerve into the hand
3
Q
carpal tunnel contents
A
- flexor pollicis longus
- flexor digitorum superficialis (x4)
- flexor digitorum profundus (x4)
- median nerve
4
Q
carpal tunnel syndrome cause
A
compression of the median nerve within the tunnel
5
Q
carpal tunnel syndrome presentation
A
- clumsiness, pain in hand, weakness in hand
- numbness (worse at night) and tingling in median nerve distribution (affecting thumb and lateral 2.5 fingers, but not the palmar surfaces)
6
Q
carpal tunnel syndrome diagnosis
A
- thenar muscle wasting
- positive Tinel’s and Phalen’s tests
7
Q
carpal tunnel syndrome management
A
- NSAIDs
- night time splint
- steroid injections
- decompression via division of transverse carpal ligament
8
Q
cubital tunnel syndrome risk factors
A
- trauma
- osteoarthritis
- rheumatoid arthritis
9
Q
what is the cubital tunnel
A
space between the medial epicondyle of the humerus and the tendon of flexor carpi ulnaris
10
Q
cubital tunnel syndrome cause
A
compression of the ulnar nerve as it passes through the tunnel
11
Q
cubital tunnel syndrome presentation
A
- clumsiness
- forearm/hand pain
- numbness and tingling in ulnar nerve distribution
- distortion of hand (ulnar claw)
12
Q
cubital tunnel syndrome diagnosis
A
- hypothenar muscle wasting
- positive Tinel’s and Froment’s tests
- nerve conduction studies
13
Q
cubital tunnel syndrome management
A
- NSAIDs
- surgical release of inter-muscular septae
