Proximal humerus fractures account for approximately 4-7% of all fractures in adults. [11] [8] It is the most common fracture of the humerus, as well as the most common fracture at the shoulder girdle. [11] [8] They are more common in women than men, and occur more often in older adults.
A humerus fracture is a break of the humerus bone in the upper arm. [1] Symptoms may include pain, swelling, and bruising. [1] There may be a decreased ability to move the arm and the person may present holding their elbow. [2]
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...

A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
A bone fracture of the shoulder involves a partial or total crack through one of the three bones in the shoulder, the clavicle, the scapula, and the humerus. The break in a bone usually occurs as a result of an impact injury, such as a fall or blow to the shoulder. Fractures usually involve the clavicle or the neck (area below the ball) of the ...
The shoulder joint is a "ball-and-socket" joint. [5] However, the 'socket' (the glenoid fossa of the scapula) is small, covering at most only a third of the 'ball' (the head of the humerus). It is deepened by a circumferential rim of fibrocartilage, the glenoidal labrum. Previously there was debate as to whether the labrum was ...
The humerus is one of the three long bones of the arm. It joins with the scapula at the shoulder joint and with the other long bones of the arm, the ulna and radius at the elbow joint . [ 6 ] The elbow is a complex hinge joint between the end of the humerus and the ends of the radius and ulna.
