tension ceases. In view of such a displacement, the natural mode of reduc-tion would seem to be one that would carry the diaphysis back-ward, and thus restore the corresponding facettes to their normal Explanation of^Plate.—Figs, i and 2 represent the head and part of the shaft of the humerus,from a boy ten years of age, and are photographed life-size. These have been separated by macer-ation, and replaced. Fig. 1 gives a profile of the bone regarded from its external aspect. Fig. 2gives a profile of the same bone regarded from its internal aspect. The dotted line A indicates theanatomical neck. The epiphyseal line B is seen to correspond with the anatomical neck alongnearly one-half of its length, and diverges nearly at a right angle below the tuberosities. Fig. 3represents the same bone in the position it retains after fracture along the epiphyseal line. Thesmaller facette of the superior diaphyseal surface is locked with the larger facette of the correspondingsurface of the head.
Text Appearing After Image:
EPIPHYSEAL FRACTURE OF THE HUMERUS. 435 positions. This I succeeded in doing, not by extension, but by-carrying the humerus fonvard and upward. The head will rollupon the glenoid surface in any motion of the arm, untilrestrained by its capsule. While the humerus is still back of thecentral line of the body, the head is rolled upward, and longbefore the humerus is brought up perpendicularly, the capsule atthe lower border of the head has become tense, thus holding itfirm while the humerus, being drawn up and restrained by itsmuscles, slides the diaphysis backward, producing a coaptationof the corresponding facettes. If these facettes have changedtheir position, or rather if one is entirely thrown forward, andthe internal facette of the diaphysis is brought and retained incontact with the external one of the head, it must be obviousthat when the shaft is hanging perpendicularly, the head mustbe rolled in such a position that the arm, if there were no frac-ture, would be nearly at right
