The greater tuberosity of the humerus is located at the lateral and anterior local elevation of the humeral head and is the stop of the supraspinatus tendon. This area is prone to injury, such as shoulder trauma that can cause avulsion fractures of the greater tuberosity, and rotator cuff tears that can cause damage to the greater tuberosity stop, both of which can lead to shoulder pain and limited motion, sometimes combined with anterior and inferior dislocation of the shoulder joint. After manual repositioning, the shoulder joint should be kept under brake to be able to promote local recovery of the avulsion fracture. If the humeral greater tuberosity fracture is not fully repaired, it can lead to supraspinatus muscle atrophy and the patient will experience weakness in shoulder forward flexion, supination and abduction. Therefore, once an injury to the greater tuberosity of the humerus has occurred, it should be given high priority and treated promptly.
