RÉSUMÉ
PURPOSE: To evaluate the results of internal fixation with bifurcate angled blade plate and tension band wiring of greater tuberosity or rotator cuff for the unstable proximal humerus fracture. MATERIALS AND METHODS: Nineteen cases of unstable proximal humerus fracture who were followed up for more than 1 year were treated using bifurcate angled blade plate and tension band wiring between March 2003 and March 2005. Average age of the patients was 46.5 years (range, 24 to 69), and there were 9 male and 10 female patients. The radiological results were evaluated by bony union and neck shaft angle. In addition, the clinical results were evaluated by Neer's evaluation criteria. RESULTS: In 18 out of 19 cases, bony union was obtained in average 12.5 weeks after operation. The neck shaft angles of sixteen cases were between 120 and 140 degrees by Paavolainen method. According to Neer's evaluation criteria, 17 cases showed excellent or good results. CONCLUSION: The patients treated using bifurcate angled blade plate and tension band wiring could exercise earlier because of good initial stability. Also, the radiological and clinical results were relatively good. The treatment of unstable proximal humerus fracture with bifurcate angled blade plate and tension band wiring was considered as a good method.
