Treatment of painful median nerve neuromas with radial and ulnar artery perforator adipofascial flaps

Purpose To review the outcomes of 8 patients with painful median nerve neuromas at the wrist treated with external neurolysis and covered with pedicled perforator adipofascial flaps. Methods Between 2004 and 2010, we treated 8 patients, who had a mean age of 37 years, and who had posttraumatic painful median nerve neuromas at the level of the wrist but with retained median nerve function. All of them reported neuropathic pain and had a positive Tinel's sign over the site of the presumed neuroma. The surgical procedure included external neurolysis and coverage with an ulnar artery perforator adipofascial flap (4 patients) or with a radial artery perforator adipofascial flap (4 patients). Patients were reviewed after a mean follow-up of 41 months (range, 18-84 mo). Preoperative and postoperative pain was measured with a visual analog scale. Results Pain improved from a preoperative mean value of 7.8 to a postoperative mean value of 3.6. There was complete resolution of pain in 5 patients, mild pain persisted in 2 patients, and 1 patient reported no improvement. No complications occurred at the donor site. Conclusions Vascularized soft tissue coverage of painful median nerve neuromas is an effective treatment. We do not believe that a free flap is of any particular advantage over a local pedicle flap which we suggest using to protect the median nerve.
