Congenital Coxa Vara.
—In a general discussion of congenital coxa vara, Roederer1 states that two conditions quite different in their etiology and their course can be differentiated. The early rachitic coxa vara has a very deformed head and marked osteoporosis with a wide oblique epiphyseal line, while congenital coxa vara shows an intact femoral head with normal osseous density and a normal epiphyseal line almost vertical in direction. In congenital coxa vara deformities of the head come slowly with use. Often the lesion is unilateral. The deformity is one of faulty development of the femoral neck; there may be shortness of the femoral neck, or the upper portion only may develop into a hooked process, or the neck may not develop at all. Many persons with coxa vara are able to lead a fairly normal existence, but later arthritis develops with increased density of the head. Treatment
