Two-plate fixation for humeral shaft non-unions.
PURPOSE. To review 22 patients who underwent 2-plate fixation for non-union of the humeral shaft. METHODS. 13 women and 9 men aged 32 to 76 (mean, 48) years underwent fixation for non-union of the humeral shaft, using a 2-plate construct, together with decortication, debridement, and bone grafting. The two 3.5-mm reconstruction plates were parallel and lying at 90 degrees to each other and fixed with screws purchasing into at least 6 cortices of each fragment for both plates. Fractures were located in the upper third (n=8) or middle third (n=14) of the humerus. Initial treatments included casting (n=9), coaptation splinting (n=8), multiple retrograde pinning (n=4), and Marchetti-Vicenzi nailing (n=1). 18 non-unions were atrophic and 4 were hypertrophic. Shoulder and elbow range of motion as well as functional results were evaluated. RESULTS. The time for union was 4.6 (range, 4-6) months. No implants were loose or broken. No nonunion or infection was noted. Functional results were excellent in 17 and good in 5 patients. One patient had iatrogenic radial nerve palsy that recovered within 3 months. CONCLUSION. Two-plate fixation achieves good results for humeral shaft non-unions.
