Ulnar nerve anterior transmuscular transposition is a well-accepted surgical technique for the treatment of ulnar nerve entrapment or subluxation at the elbow. The procedure, which addresses both compression and traction forces on the nerve, may be performed with the patient in the lateral decubitus position, allowing direct access to and excellent visualization of the ulnar nerve through an incision on the posteromedial aspect of the elbow. This report reviews the surgical indications and contraindications, pertinent anatomy, patient positioning rationale and method, surgical technique, postoperative management, and potential complications for this ulnar nerve transposition procedure. Discussion of the technique and an illustrative case are also provided.
