Varieties of Fractures.--Fractures of the upper end of the humerus may be classified as: (1 ) fractures of the head; (2) fractures of the anatomical neck; (3) fractures through the tuberosities; (4) fractures (isolated) of the greater or lesser tuberosity; (5) separation of the upper epiphysis; (6) fractures of the surgical neck.

Fractures of the Head of the Humerus (Fig.--Fractures involving the head of the humerus without injury to other parts of the bone are extremely rare. Fractures involving the head are generally found in conjunction with fractures of the anatomical neck or tuberosities, or with anterior dislocation of the humerus. Fractures of the head may be fissured fractures. The fragments may be impacted or displaced, and can generally only be detected by X-ray examination. They should be differentiated from fracture of the anatomical neck, subdeltoid bursitis, and sprain-fractures. Cases have been recorded by Gosselin and Gross, and by Malgaigne. Etiology.--The articular surface may be chipped off, or may be indented, or the line of fracture may extend out through the anatomical or surgical neck, or the tuberosities. These fractures are occasionally seen accompanying dislocation. Fig. 323.--Incomplete fracture of the head of the humerus.
