Abstract
The fixation technique of bony fragments is crucial for the bone union of the tuberosities after humeral head replacement (HHR) for a comminuted fracture of the proximal humerus. To increase the bone union rate, we reduce tuberosities to overlap on the humeral shaft by approx. 1 cm and fix them with cable wire. Herein, we retrospectively investigated the clinical and radiographic outcomes of our procedure. Twenty-six patients who underwent cementless HHR for the treatment of comminuted fractures of the proximal humerus were investigated. The Constant-Murley score, active shoulder mobility, and bone union rate were evaluated. The mean duration of follow-up was 56.3 months (range 24-197). At the final follow-up, the average Constant-Murley score was 58 (range 40-76). Forward elevation was 126° on average (range 35°-180°). Twenty-three cases (88%) showed bone union between the tuberosities and the shaft at an average follow-up of 4.1 months (range 4-5 months) after surgery. Non-union was noted in 1 case, and bone resorption was noted in 2 cases. The bone union rate and the clinical outcome of our procedure were relatively favorable
