In 1945 there were a number of papers dealing with conditions involving shoulder, neck and jaw.
Conditions of the Shoulder.
—Dislocations: Pettersson658 discusses the pathology of the dislocated shoulder. He reviews the anatomy of the shoulder joint with special emphasis on the tendon aponeurosis. The physiologic movements of the shoulder joint are described, especially the synchronous movement of "scapulohumeral rhythm." The aid of roentgen rays in diagnosis of rupture of the tendon aponeurosis is illustrated. This is done by the method of Lindbloom (1939) with the use of "perabrodil" (iodopyrin injection). Tears and rents in tendinous cuff have been shown to occur at as early an age as 30 and have been found to increase with age. Some claim that rupture results from trauma; others as a result of progressive degenerative processes.The after-care of dislocations following reduction is emphasized by Tavernier.659 Two cases are reported in which
