The purpose of this paper is to review briefly the literature and to report five additional cases of what is referred to by various writers as congenital, infantile or cervical coxa vara. Coxa vara is an anatomic term now used to indicate a diminution from normal of the angle between the neck and the shaft of the femur.
Since coxa vara is caused by the strain of weight-bearing on a weakened femoral neck, one finds that the cases fall into certain groups, depending on the etiology of the weakness. A classification now generally used is as follows:
1. Congenital coxa vara (the infantile or cervical type of Elmslie and Fairbanks).
2. Acquired coxa vara.
(a) Due to local pathologic processes such as cervical fracture, tuberculous or pyogenic infection, metastatic malignancy and similar conditions.
(b) Adolescent coxa vara, which Noble and Hauser believe is due to pituitary dysfunction.
(c) Coxa vara
