WITH A NOTE ON THE PATHOLOGY BY DR. T. P. PROUT.
The surgical treatment of brachial birth palsy rests on the pathologic lesion, and this, in turn, for its type and distribution, depends on the etiologic factor at work.In a publication on this subject1 it was shown as a result of twenty dissections and many experiments on infantile cadavers, that tension (overstretching) of the nerve roots of the brachial plexus was the essential causative factor of this lesion. Observations of the lesions in the series of nine operative cases led to the same conclusion. The roots give way from above downward.This overstretching is caused only by pulling the head and shoulder away from each other, i. e., pulling on the shoulders to deliver the after-coming head in breech cases or pulling on the head when the shoulders are obstructed in vertex cases.After this study had been
