![]() Middle age/elderly are most commonly affected.Can also occur during seizures or electric shock when fracture may be associated with a posterior shoulder dislocation.Usually after a fall on to an outstretched hand from standing height.Proximal humerus fractures often occur in older patients after a low-energy fall. Distal humeral fractures are discussed in the separate Elbow Injuries and Fractures article. Fractures of the distal humerus in the adult account for approximately one third of all humeral fractures. One method is to classify them as:įracture of the supracondylar (distal) humerus is one of the most common fractures encountered in children. In the elderly, pathological fracture should be considered.Ĭlassification of humeral fractures is difficult. In children the possibility of non-accidental injury should be borne in mind when taking the history and examining the child, especially in very young children. ![]() Mechanism of injuryįractures of the humerus usually result from falls or direct trauma. ![]() The medial and lateral epicondyles are at the lower end of the humerus, and the joint surface consists of the capitulum (articulates with the head of the radius) and the trochlea (articulates with the ulna). The radial nerve runs posteriorly around the middle third of the humeral shaft in the spiral groove. The long head of biceps runs between the tuberosities in the bicipital groove, and the surgical neck is just below the greater and lesser tuberosities. The anatomical neck separates the greater and lesser tuberosities from the humeral head. The humeral head articulates with the glenoid fossa of the scapula.
