Upper Extremity Entrapment Neuropathy

Abstract

Entrapment neuropathy is a condition characterized by motor, sensory and autonomic deficits that occur as a result of compression of the peripheral nerve at certain points along its anatomical course for different reasons. Although each peripheral nerve has anatomical or compression-appropriate areas, this can occur at any point along the course of the nerve. Entrapment neuropathies usually occur in areas where the nerve passes through a channel consisting of bone and fibrous tissue. External and internal factors play a role in the etiology of entrapment neuropathies. Among the factors that cause neuropathy, anatomical variations, trauma, metabolic diseases, tumors, synovitis and vitamin B6 deficiency are the most common ones.

“…In these patients, microangiopathic changes at the level of the nerve can lead to decreased myelination and nerve fiber loss, often causing irreversible changes [5][6][7]. Finally, other systemic diseases, trauma, tumors, and metabolic diseases can all contribute to developing UE neuropathy [8].…”
