Obstetric paralysis, a paralysis produced during birth, is due to an injury to the nerves of the brachial plexus. The resultant paralysis is characteristic; the arm hangs vertically, the elbow extended, the forearm pronated and the whole arm inwardly rotated. The paralysis is usually flaccid.
I shall endeavor in this paper, by a review of all the literature, to give the reader the various theories as to the causes of the paralysis, as well as to offer the conclusions I have reached by a study of 470 cases. Certain experimental work which I have done, with the idea of determining clearly the etiology and pathology, will be described and conclusions drawn therefrom. The pathologic and clinical aspects of the condition will be discussed and analyzed, and the treatment, operative and nonoperative, will be dealt with under appropriate headings. Definite conclusions will be drawn from the study of about 500 cases,
