Arthroscopic subscapularis tenolysis: a technique for treating refractory glenohumeral stiffness following open reduction and internal fixation of a displaced three-part proximal humerus fracture.

This case illustrates the treatment of a stiff shoulder following open reduction and internal fixation of a three-part fracture of the proximal humerus. Motion could not be improved with physical therapy or with manipulation under general anesthesia. Arthroscopic subscapularis tenolysis provided a dramatic increase in range of motion. The unique pathological findings may render such cases refractory to manipulation because of thick unyielding scar tissue. In such cases, arthroscopic subscapularis tenolysis may provide the only means of improving the final range of motion.
