In connection with some work which has been done during the past four years at the New York Orthopaedic Hospital, on anteversion of the femoral neck, when found in connection with congenital dislocation of the hip, I recently made a study of 200 normal femora at the anatomic museum of the College of Physicians and Surgeons, with the view of determining the frequency and extent of this condition in the normal femur, and beyond what degree it might be considered an abnormality, sufficient to justify a corrective osteotomy when found complicating congenital dislocation. The method employed in determining the angle of deformity was as follows: A line was drawn through the center of the upper surface of the head and neck of the femur parallel to its long axis.
