Result of avulsion of C5 & C6 nerve roots? | Erb-Duchenne-type paralysis |
Result of avulsion of C8 & T1 nerve roots? | Klumpke paralysis |
Mechanism of injury in Erb-Duchenne-type paralysis? | Usually result of trauma to the shoulder tip in motorcycle accidents, or pulling too hard on infants head when shoulder is stuck during delivery |
Mechanism of injury in Klumpke paralysis? | Tends to occur when pt attempts to break a fall by grabbing something, or when arm is trapped in a moving machine |
Most likely level of root lesions in cervical spondylosis? | C5, C6 |
Classic neurological condition that was originally recognized as a sequel to immunization procedures involving injection into the deltoid muscle? | Brachial Neuritis (serum neuritis, neuralgic amyotrophy); Usually believed to be inflammatory process to roots, not from direct trauma; consistently involves serratus anterior (scap winging) |
A lesion of what nerve should be suspected when pincer movement of the index finger and thumb is lost? | Anterior Interosseus Nerve ( a branch of the median nerve - C7) |
What nerve lesion is suspected with winging of the scapula during arm elevation or pushing forward? | Long thoracic nerve (C5, C6, C7) |
What are the 4 major presentations of carpal tunnel syndrome? | Sensory; Motor; Autonomic, and Classic (which includes elements from all of the above) |
A lesion of what nerve should be suspected when there is significant weakness of the wrist extensors, and particularly of the index finger and thumb? | Posterior Interosseus Nerve ( a branch of the radial nerve) |
What movements would be compromised in a supinator compression syndrome? | wrist extension is weak with radial deviation due to weakness of extensor carpi ulnaris |
Name the 3 main causes/types of radial nerve lesions? | Crutch palsy (axilla); triceps involved. Saturday night palsy / humerus fracture (spiral groove) wrist drop; Supinator (affects posterior interosseus nerve - thumb extensors, index finger extensors weak) |
What nerve lesion may be involved with repeated trauma to the heel of the hand? | Deep branch of the Ulnar nerve (purely motor) |
Anterior interosseus nerve lesion is also known as _______ - _______ syndrome? | Kiloh-Nevin |
