[mononeuropathies] Flashcards
trauma
entrapment
=>2 peripheral nerves involved
Systemic
WARDS PLC
Wegeners AIDS/amyloid Rheumatoid DM Sarcoidosis pAN Leprosy Carcinoma
Electromyography
LOAF
Lumbricals
Opponens pollicis
Abductor pollicis brevis
Flexor Pollicis brevis
Radial 3.5 fingers and palm
Anterior interosseous nerve
none - no sensory branches
weak flexion of
distal phalanx of thumb and index finger
flexor pollicis longus
radial side of flexor digitorum profundus
combined median and anterior interosseous nerve signs
C6 - T1
Granulomatosis with polyangiitis
elbow
Hypothenar eminence
medial 1.5 fingers and ulnar side of hand
ulnar nerve
ulnar nerve
MCPs
you expect a greater injury to produce a bigger ‘claw’ but it doesnt
flexor digitorum is damaged. therefore less pronounced flexion of DIP and less promounced claw hand
flexor digitorum is intact therefore flexion occurs
un opposed extension of MCP
Un oppossed flexion of IP
Damage to median nerve
inability to flex lateral MCP/IPs
flexor digitorum profundus
C7 to T1
Wrist drop
anatomical snuff-box
C3 C4 C5
phrenic nerve palsy
Meralgia paraesthetica (lateral cutaneous nerve of the thigh)
L2-L3
inguinal ligament
L3 - S3
Sciatic
as it winds around fibular head (sitting x-legged)
dorsum of foot
common peroneal
plantarflexion (stand on tiptoes)
inversion
Median nerve
“wake and shake”
pain worse at night. Waking and shaking the arm relieves
splinting
local steroid injections
decompression surgery
Phalens
Tinels
