Proximal means it is the end of the bone that is closest to the body. This typically happens after a fall on the affected side, followed by pain in that arm or shoulder. This is different than a dislocated shoulder, separated shoulder, broken collarbone or torn rotator cuff. About 5% of all fractures are proximal humerus fractures. There are different types of proximal humerus fractures. Depending on the type of fracture, it may be treated with or without a surgery. 85% of proximal humerus fractures are treated without surgery. Fractures are clas- sifi ed based on the number of fracture pieces, displacement of the pieces, involvement of the shoulder joint surface, and dislocation of the shoulder. 2-PART FRACTURE: This is when the proximal humerus is broken into two pieces, meaning there is one fracture line on x-ray. Commonly, this will be a fracture of the greater tuberosity, which is the part of the humerus where the rotator cuff attaches. When the humerus is forced in one direction (typically during a fall), and the rotator cuff remains intact, the greater tuberosity is broken off the humerus.
