Abstract

We report the use of a hypothenar pedicled fat flap to cover the median nerve in recalcitrant carpal tunnel syndrome. Forty-five patients with recurrent symptoms after previous carpal tunnel surgery were included in this study. Patients with incomplete release of the transverse carpal ligament were not included.We performed an anatomical study on 30 cadavers. The original technique with the section of the deep branch of ulnar artery was modified. The flap could be transferred onto the median nerve without stretching. The median follow-up was 45 months (range, 12–80 months). Pain completely disappeared in 41 patients with normal nerve conduction. Based on clinical and electromyographic signs, the global results showed excellent results (49%), 19 good results (45%), two average results (4.5%) and two failures (2%).The use of a hypothenar pedicled fat flap to cover the median nerve in recalcitrant carpal tunnel syndrome is a simple and efficient technique which improves the trophic environment of the median nerve and relieves pain.
