Measuring from the acro-mial process to the external epicondyle of the humerus, the 128 FRACTURES OF THE HUMERUS upper arm, in a subcoracoid dislocation, is lengthened. A softcrepitation may be detected in manipulating the shoulder, whichsimulates bony crepitus. Fracture of the Anatomical Neck (see Figs. 146, 147, 148,149, 150, 151).—This is rare. It occurs in elderly of the shoulder is evident. Anesthesia is necessaryfor a careful examination with deep palpation. There is thick-ening of the neck of the bone. Crepitus will be felt unless thefracture is impacted. There will be pain upon moving the shoul-. Fig. 146.—Fracture of the anatomical neck of the left humerus. Atrophy of the shouldermuscles.

Abnormal mobility may be felt high up the shaft close tothe head of the bone. This fracture lies wholly within the cap-sule of the joint. Separation of the Upper Epiphysis (see Figs. 152, 153, 154,155, 156).—The separation of the upper humeral epiphysis willnot necessarily open the joint cavity, for the capsular ligament isfirmly attached to the epiphysis and the synovial membrane is butloosely attached to the diaphysis.
