Abstract

This retrospective study evaluated the results of 66 decompressions of the median nerve in the forearm in 62 patients (4 bilateral) done between from 1995 through 1998. Mean duration of symptoms was 28.9 ± 38.6 months, and mean post-operative follow-up was 32.7 ± 27.5 months. Multiple nerve compressions were common in this population, with 74% of patients having ≥ 2, and 29% having ≥ 3. Documentation of the presence of proximal median nerve compression was done with the Pressure-Specified Sensory Device™ by measuring the cutaneous pressure threshold over the thenar eminence. At surgery, all sites of compression of the median nerve were released, including the lacertus fibrosis, deep head of the pronator, and a distal superficialis arch. No patient had a Ligament of Struthers. A high origin of the superficial head of the pronator teres was found in 27% of the patients, and may have contributed to their symptoms. Complete symptomatic relief was obtained in 51.5%, partial relief in 44.0%, and no relief in 3.5% of the 66 forearm. Eighty percent of the workmen's compensation patients were returned to work.
