Abstract:
BACKGROUND:The best repair method for proximal humeral fractures remains controversial at present. Although different techniques have been described for proximal humerus fractures, al these techniques have high postoperative complications, such as cut-out or back-out of the screws, nonunion, and subacromial impingement. Given the shortcomings of conventional plate fixation system, we had designed a new type of proximal humeral wing-shape anatomical plate for the repair of proximal humeral fractures. OBJECTIVE:To evaluate clinical outcomes and complications of proximal humeral wing-shape anatomical plate fixation for proximal humerus fractures. METHODS:A total of 60 patients with proximal humerus fractures who underwent proximal humeral wing-shape anatomical plate fixation from September 2012 to September 2013 were retrospectively analyzed. According to Neer classification system, 24, 31 and 5 patients had 2-part, 3-part, and 4-part fractures, respectively. Functional evaluation of the shoulder was done using Constant-Murley score and Visual Analogue Scale was utilized for assessing the degree of shoulder pain. RESULTS AND CONCLUSION:Al 60 patients were fol owed up for 12-24 months after fixation, and obtained bone healing. The healing time was 15.3±2.7 weeks (range 12-20 weeks). At the final fol ow-up, the Constant-Murley score was 81.5±14.6 (range 45-98). The mean Visual Analogue Scale score was 0.9 ± 0.9 points (range 0-7 points). During the fol ow-up, the overal rate of complications was 18%in 11 cases of 60 cases, including intraarticular screw penetration in 3 patients (5%), back-out of the screws in 1 patient (2%), varus malunion in 5 (8%) patients (containing 2 cases combined with screw penetration), humeral head necrosis in 2 patients (3%), subacromial impingement in 1 patient (2%) and superficial infection of incision in 1 patient (2%). No cases of avascular necrosis or hardware failure were noted. Above data suggested that self-made new-type proximal humeral wing-shape anatomical plate fixation for repairing proximal humerus fractures can obtain satisfactory outcomes, effectively reduce the incidence of postoperative subacromial impingement, is helpful to the recovery of shoulder function, and deserves to be further used.
