neuralgic amyotrophy

(redirected from brachial plexus neuropathy)

neu·ral·gic a·my·ot·ro·phy

a neurologic disorder, of unknown cause, characterized by the sudden onset of severe pain, usually about the shoulder and often beginning at night, soon followed by weakness and wasting of various forequarter muscles, particularly shoulder girdle muscles; both sporadic and familial in occurrence with the former much more common; often preceded by some antecedent event, such as an upper respiratory infection, hospitalization, vaccination, or nonspecific trauma; usually attributed to a brachial plexus lesion, because the nerve fibers involved are most often derived from the upper trunk.

neuralgic amyotrophy

[noo͡ral′jik ā′mīot′rəfē]
a brachial plexus disorder characterized by sudden pain and muscle weakness in the upper limbs and sometimes by muscular wasting or atrophy. The cause is unknown. Also called Parsonage-Turner syndrome.

Neuralgic amyotrophy

shoulder girdle syndrome

A condition evoked by upregulation of the sympathetic nervous system.
 
Aetiology
Contusions, fractures, neurovascular injuries.
 
Clinical findings
Acute searing pain, marked muscle-weakness, vasomotor lability, oedema, osteoporosis and, with time, wasting of the shoulder girdle and upper arm.
 
DiffDx
• Acute phase—Frozen shoulder, calcific tendonitis or arthritis.
• Chronic phase—Rotator cuff tears, nerve root compression.
