Avulsion fractures of the greater tuberosity of the humerus occur frequently in patients in clinical practice. The etiology is mostly due to external irritation, most commonly due to dislocation of the shoulder joint in combination with an avulsion fracture of the greater tuberosity. An avulsion fracture is primarily a tear of the deltoid muscle at the greater tuberosity stop, producing a greater tuberosity fracture. If the displaced humeral tuberosity fracture is not large, most of the treatment is conservative, with topical plasters to activate blood circulation and remove blood stasis, and a plaster brace or brace to fix the shoulder joint. If the fracture is large and displaced, surgical treatment is usually performed by incision and internal fixation with hollow nails or plates. The patient should be seen promptly after the fracture, and the doctor will take symptomatic treatment according to the specific situation of the fracture.
