Shoulder and elbow function following Marchetti-Vicenzi humeral nail fixation

Humeral nailing has been associated with reduction of shoulder and elbow function. We present the results of fixation of 15 diaphyseal humeral fractures with Marchetti-Vicenzi nails (B Braun Medical Aesculap). Shoulder and elbow functions were assessed by the Constant shoulder and Mayo elbow scoring systems. The average Constant Shoulder score was good (82.5/100) and the average Mayo Elbow Score was excellent (95.4/100). The indications for surgery included nonunion, pathological fractures and poor fracture position. The mean follow-up was 67 weeks with an average interval to surgery of 19 weeks. The mean time to union was 19 weeks. All the fractures united without any patient requiring any further procedure. There were two postoperative radial nerve palsies and one median nerve palsy, however two patients had complete recovery and one had partial recovery of the radial nerve. There was one deep infection requiring removal of the implant. There were no implant failures. Based on our experience, the Marchetti-Vicenzi humeral nail appears as a relatively safe implant and its use has been associated with preservation of good shoulder and elbow functions.
