Nonoperatively Treated Proximal Humerus Fractures: Randomized Trial of Immediate Versus Delayed Initiation of Exercises.

Abstract

There is debate about when to start exercises in the nonoperative treatment of a proximal humerus fracture. This randomized trial compared immediate and one-month delayed shoulder exercises in the nonoperative treatment of fractures of the proximal humerus. Twenty-six patients with a fracture of the proximal humerus who chose nonoperative treatment were randomized to start pendulum exercises within a few days and 24 were randomized to delayed exercises and started with active self-assisted stretching 1 month after fracture. Three and six months after the injury, patients completed the Disabilities of the Arm Shoulder and Hand questionnaire to measure capability, a measure of pain intensity, and had motion measurements. There was no significant difference in forward flexion (primary outcome) six months after injury between patients that started motion exercises immediately compared to 1 month after injury (p = 0.85). There was no difference in any motion measurement, pain intensity, upper extremity specific disability (DASH score) three or six months after injury. Delaying exercises for a month does not affect recovery from nonoperative treatment of a fracture of the proximal humerus. People can choose whether to start exercises immediately or wait until they feel comfortable.
