Case ReportsNerve entrapment syndromes in the upper extremity contralateral to amputation.
Five cases are reported of upper extremity amputation with no metabolic disease. Patients experienced pain, paresthesia and weakness in the intact extremity associated with electrophysiologic evidence of entrapment neuropathies. All patients did heavy manual work, and all had carpal tunnel syndrome. ⋯ Patients who did not use a prosthesis felt relief of symptoms following surgical release. Possible mechanisms which produce nerve entrapment syndromes in patients with upper extremity amputations are use of one limb for heavy manual work over prolonged periods, direct compression of neural structures from the axilla loop of a figure-8 harness, and compression of neural structures in the axilla resulting in entrapment at a distal site. Changing the figure-8 harness should be considered prior to surgical decompression for patients who have upper extremity amputations with entrapment syndromes.
