Prevalence of Concurrent Disorders of Ulnar Nerve Entrapment at the Elbow and Carpal Tunnel Syndrome Ahvaz Imam Khomeini Hospital During 2009 to 2012

Abstract

Carpal tunnel syndrome (CTS) is the most well-known and frequent form of median nerve entrapment, and accounts for 90% of all entrapment neuropathies. Entrapment neuropathies of the ulnar nerve are relatively common with ulnar neuropathy at the elbow more prevalent than ulnar neuropathy at the wrist. The diagnosis of ulnar neuropathy at the elbow is usually confirmed in a relatively straight – forward manner by nerve conduction studies.Electrophysiology studies performed on 63 patients with carpal tunnel syndrome that had referred to Golestan hospital, Ahvaz, Iran from 1388-1391 and neuropathies of the ulnar nerve was evaluated in them. Entrapment of the ulnar nerve was seen in 49/2% of patients. This disease was more in men significantly (p=0.001). The mean of motor conduction velocity in both hand was different in ulnar nerve conduction disturbance group importantly (p=0.001). As finding results, Entrapment neuropathies of the ulnar nerve can associate with carpal tunnel syndrome amount. It is better evaluation of the ulnar nerve are performed with carpal tunnel syndrome at the same time to prevent from misdiagnosis and treatment.
