Thejoint cavity was empty and the head of the humerus could bepalpated in MohreTiheims groove. The arm was slightly short-ened, the motion of the arm greatly impelled, and the patient suf-fered from intense periodical pain, which seemed to be dependentupon nerve-pressure. The Kontgen rays revealed the typical signs of subcoracoid dis-location. At the anterior surface of the neck of the scapula athickened area was noticed, which made the author suspect thatthere was a co-injury of this portion, but the skiagraph showed thebones to be intact. As the operation proved afterward, the thick-.

After various methods of reduction were tried in vain underanassthesia, a nearly semilunar incision was made which began at 188 THE RONTGEN RAYS the acromion, and running over the intertubercular sulcus wasextended vertically alongside the anterior surface of the both the joints and the acromion were exposed. After care-ful and extensive dissection of adhesions the author succeeded inrotating the head of the humerus in its glenoid cavity. Therewas a pronounced tendency to forward displacement whichcould not be overcome by additional exposure. Therefore, theauthor fastened the head of the humerus in the cavity by suturing
