38
Upper trunk of brachial plexus injury
ERB-DUCHENNE Palsy WAITER’s Tip
39
Lower trunk brachial plexus injury
KLUMPKES Palsy Claw hand, wrist drop
40
Causes of lower brachial plexus trunk injury
Thoracic outlet syndrome: compressed between clavicle and first rib Pancoast syndrome: apical lung tumor Forceful abduction
41
Axillary neuropathy cause and S/S
Proximal humerus fracture/ dislocation Deltoid weakness and shoulder numbness
42
Axillary neuropathy vs C5 radiculopathy
Axillary: no biceps involvement
43
Brachial plexitis
Inflammation of brachial plexus causes arm weakness and burning shoulder/neck pain
44
Radial Neuropathy
“saturday night palsy” Wrist drop
45
Handcuff neuropathy nerve and S/S
Cheiralgia parasthetica: isolated dorsal lateral hand sensory loss Superficial radial nerve
46
Median neuropathy
Honeymooner’s palsy Weakness in wrist and 2/3 digit flexion (preachers hand)
47
Carpal tunnel syndrome
Median nerve compression as it passes with hand tendons
48
Ulnar palsy
Ulnar sensory loss and ulnar claw 4/5 digits down with sensory loss
49
Median and ulnar palsy
Simian hand ape together strong Palm sensation gone
50
Ulnar neuropathy cause and signs
Medial epicondyle injury Ulnar claw
51
Femoral neuropathy signs
Weakness in thigh flexion and knee extension, patellar reflex loss, anterior thigh sensory loss
52
Femoral neuropathy vs L3/L4 radiculopathy
L3/L4 will have weakness in adduction of thigh
53
Sciatic neuropathy causes and signs
Causes: posterior hip dislocation, acetabular fracture, buttocks injections in wrong place Weakness in all foot and ankle muscles and knee flexion Loss of achilles reflex
54
Fibular nerve palsy signs and causes
Causes: forcible foot inversion, compression, trauma FOOT DROP dorsolateral foot and shin sensory loss
55
Obturator nerve palsy
Gait instability
56
Slowed nerve conduction cause
Demyelination
57
Decreased nerve conduction amplitude cause
axonal damage
58
Weakness at multiple unrelated locations with no sensory issues
think myasthenia gravis
59
Repetitive stimulation of nerve conduction test why
In patients with myasthenia gravis, decrease in amplitude due to to decreased ATCH receptors
60
Guillain Barre signs and symptoms
Progressive motor and sensory issues Acuted demyelination often following infection in HIV
