摘要
Background Hemiarthroplasty is used to treat patients with Neer four-part fractures but the post-operative complication rate remains high, particularly with regard to shoulder joint instability. This study was aimed at evaluating the efficacy of a modified rotator cuff reconstruction and balance technique by comparing it with conventional rotator cuff restoration surgery for Neer four-part fractures. Methods This retrospective therapeutic study included 67 patients with Neer four-part fractures. Forty-five patients underwent the modified surgery and 22 control patients underwent conventional surgery. All patients were followed up for more than 3 years. Outcome was assessed by grading clinical outcome and pain and strength, measuring range of motion, and radiographic analysis. Results The Neer score was higher in the modified surgery group (84 versus 75; P = 0.009). The rate of satisfaction (Neer score 80) in the modified surgery group was higher than in the conventional surgery group (71.11% versus 40.91%; P = 0.017). Range of motion for active abduction, external rotation, internal rotation and active forward elevation was greater in the modified surgery group (all P < 0.01). The morbidity rate of post-operative instability of the shoulder joint in the modified surgery group was much lower than that in the conventional surgery group (2.22% versus 18.2%; P < 0.01). Conclusion The modified hemiarthroplasty procedure for treatment of Neer four-part fractures prevents post-operative instability of the shoulder joint and improves function of the shoulder more effectively than the conventional hemiarthroplasty procedure.
