The impact of ulnar nerve compression at the elbow on the hand function of heavy manual workers.

The objectives of this article were to study the impact of the hand function disability due to ulnar neuropathy at the elbow (UNE) on workers engaged in occupations requiring heavy hand use. Four patients (42.5 +/- 7 years old), all engaged in heavy-duty jobs, with severe conduction block but without severe axonal loss were recruited.

Compression of the ulnar nerve at the elbow by an intraneural ganglion.

A rare cause of ulnar nerve compression at the elbow is presented in this report. A 42 year old right-handed mechanic developed subacute, progressive numbness, tingling and weakness in his right hand. Electrophysiologic studies demonstrated a severe conduction block affecting the ulnar nerve in the retrotrochlear groove but without any sign of major axonal loss.
