title: Treatment of post-traumatic humeral diaphyseal nonunion with bone loss.
abstract: Four patients with post-traumatic nonunion and shortening of the humeral diaphysis were treated with a hybrid advanced Ilizarov technique. The mean age of the patients was 32 years, and the mean total amount of humeral shortening was 6.63 cm. Three nonunions were atrophic and infected, and one was hypertrophic. All patients obtained union of the humeral fracture with resolution of infection at a mean external fixation time of 8 months. Restoration of normal humeral length was achieved in two patients, with a third having a residual discrepancy of 1 cm. The final patient, who had an infected nonunion with 11 cm of total humeral shortening, had a residual limb length discrepancy of 3 cm. All had improvement in shoulder and elbow motion after treatment. Superficial pin tract infections were seen in all patients, but all responded to pin-site care and oral antibiotics. Two patients had three refractures after removal of the fixator, two of which were treated by a second application of an Ilizarov frame and one by a cast. All patients had reduced pain and improved function at completion of the treatment. The Ilizarov method, though not a panacea for all humeral nonunions with extensive bone loss, does offer a viable salvage procedure in this unusual and often complex clinical problem.
