Isokinetic strength test and functional outcomes in proximal humeral fractures treated with a locking plate

摘要

Background Despite the use of many shoulder outcome scales in subjects with rotator cuff pathology or instability symptoms, it can be problematic to select an instrumental evaluation in the shoulder trauma population. In this study we evaluated patients with proximal humeral fractures treated with internal fixation with a locking plate, analyzing the recovery of strength with an isokinetic test and its correlation with clinical and functional outcomes. Methods We enrolled 46 individuals (17 men, 29 women). The evaluation included a structured interview, measurement of ROM, isokinetic strength test and Con-stant-Murley and QuickDASH scores. The isokinetic test was performed in flexion/extension and external/internal rotation of the operated shoulder in comparison with the contralateral side and concentric contractions in all movements. The parameter tested was peak torque.
