Studies on Dysplastic Acetabula and Congenital Subluxation of the Hip Joint with Special Reference to the Complication of Osteo-Arthritis

This small monograph, written by one of Professor Waldenstrom's assistants, contains some interesting material on the anatomy and x-ray appearance of the normal hip. From his studies of hundreds of normal cases, the author evolved a method for determining whether the joint is normal or pathologic. He then examined many patients who had been roentgenographed during childhood so that a chronological study was possible. The author provides an elaborate description of methods of measuring to differentiate the normal from the abnormally developed acetabula. He discusses the connection between osteoarthritis with dysplastic acetabula and congenital subluxation of the hip. The section on arthrography is especially interesting.
