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.
