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.
Type of study/level of evidence: Therapeutic IV.
