Posttraumatic neuroma of the radial nerve treated with an autogenous epineural conduit technique. A case report.

We present the outcome of the first clinical application of a new technique using an epineural flap to bridge a short nerve defect. A 28-year-old male had suffered a radial nerve laceration at the lower third of the arm, proximal to the brachioradialis branch, 3 weeks before surgery. During surgery, a neuroma-in-continuity was excised preserving the epineural sleeve. Two longitudinal epineural flaps were created, one from the proximal and one from the distal nerve stump and used to bridge a 1-cm-long nerve defect. Each epineurium flap was sutured to the intact epineurium of the other side and additionally to each other. An electromagnetic nerve stimulator was used to enhance the nerve regeneration process. Nerve regeneration was followed up for 17 months with excellent functional results.
