Abstract: ［Abstract］ Objective Severe rotator cuff injury is a common cause of limited and unstable shoulder joint activity after the reduction of proximal humerus fracture in older people. In this study， we evaluate the prevalence of full thickness rotator cuff tear in patients with proximal humeral fractures. Methods Clinical data from 336 patients with proximal humeral fracture were retrospectively collected. We compared the incidence of rotator cuff tear in different types of fracture according to age and Neer classification. Results The proportion of elderly patients with proximal humeral fractures and rotator cuff tears increased with age. Statistically significant difference was found between patients with rotator cuff tear group and patients without rotator cuff tear group for the age of the patient （72.9±8.5 vs 65.7±9.1； t=6.912， P=0.042）. Rotator cuff tear was most common in Neer 3 greater tuberosity fracture （54.8%， 92/168）. Conclusion Patient age was found as a risk factor for full thickness rotator cuff tear in humeral proximal fractures. Full thickness rotator cuff tear was most common in Neer 3 greater tuberosity fracture.

摘要： ［摘要］ 目的 本研究旨在探讨肱骨近端骨折合并肩袖损伤与年龄分布及骨折分型的相关性。方法 回顾性分析336例老年肱骨近端骨折病人的临床资料，比较不同年龄分层肱骨近端骨折合并肩袖损伤的发生率，并根据肱骨近端骨折分型Neer分型比较不同骨折类型肩袖损伤的发生率。结果 随着年龄的增加，老年肱骨近端骨折合并肩袖损伤的病人的比例增加。合并肩袖损伤的肱骨近端骨折病人的平均年龄（72.9±8.5）与不合并肩袖损伤的病人的平均年龄（65.7±9.1）差异有统计学意义（t=6.912，P=0.000）。肱骨近端骨折分型Neer分型3部分骨折合并肩袖损伤的发生率最高，为54.8%（92/168）。结论 随着年龄的增加，老年肱骨近端骨折合并肩袖损伤病人比例逐渐增加；肱骨近端骨折分型Neer分型3部分骨折常合并肩袖损伤。
