Nerve Entrapment Syndromes in the Wrist.

The patient with compression neuropathies of the median and ulnar nerves at the wrist commonly presents with pain, paresthesias, and weakness in the hand and digits. Diagnosis of these conditions is becoming more widespread with the increased attention given to "cumulative trauma disorders" during the past decade. Successful management requires a thorough understanding of the pathophysiology of compression neuropathy and how it relates to the various diagnostic tests available today. The authors review the epidemiology, etiology, and evaluation of compression neuropathy and discuss common clinical presentations, treatment recommendations, and controversies surrounding carpal and ulnar tunnel syndromes.
