(redirected from cervical rib and band syndrome)

true neu·ro·log·ic tho·rac·ic out·let syn·drome

very chronic axon loss brachial plexopathy, caused by compromise of the distal C8 anterior primary ramus or proximal lower trunk fibers by a congenital band extending from a rudimentary cervical rib to the first thoracic rib; rare disorder, found mostly in young to middle-aged women, which presents with unilateral hand wasting and weakness, particularly involving the lateral thenar eminence; sometimes accompanied by intermittent discomfort along the medial forearm and hand.
