Abstract:
Objective To evaluate the prevalence of full thickness rotator cuff tear in patients with proximal humeral fractures,and the relationships between different risk factors.Methods Data of 113 patients with proximal humeral fractures from January 2014 to January 2016 who underwent surgical treatment were retrospectively analyzed.The general characteristics of patients (age,sex,cause of injury) were recorded and the rotator cuff was evaluated preoperatively on MRI and explored intra-operatively.We calculated and compared the incidence rate of age,sex in patients with and without rotator cuff tear.And the incidence rate of rotator cuff tear in different types of fracture according to Neer classification was calculated.Results The full thickness ro tator cuff tear were indentified in 28 patients (24.8％),and 21 of them had been confirmed by MRI preoperatively.Statistical significant difference was found between patients with rotator cuff tear group (average of 75.11± 10.89 years old) and without rotator cuff tear group (64.68± 13.43) for the age of the patient.Full thickness rotator cuff tear was most common in Neer 3 GT fracture (33.3％,8/54),followed by Neer 2 GT (26.67％,4/15) and Neer 2 SN (17.65,6/34),however,no full thickness rotator was found in Neer 4 type fracture.There were 4 patients with total rotator cuff tear who had symptom of shoulder before the operation.The other 24 patients had no symptom of shoulder.Conclusion Patient age was found as a risk factor for full thickness rotator cuff tear in humeral proximal fractures with the rate of 24.8％.Full thickness rotator cuff tear was most common in Neer 3 GT fracture.
