Hypocalcemia: a sign of severity of necrotizing fasciitis.

The growth disturbance of the superior end of the femur which is related to a superior lateral epiphysiodesis of the femoral neck is known as caput valgum (C.V.). Most often, it appears after the treatment of a congenital dislocation of the hip (C.D.H.) which can also produce many other growth disorders of the hip. Fifteen children (seventeen hips) presenting similar evolution and morphological abnormalities have been reviewed. We performed nine surgical procedures most of the time for painful hips because of excentration of the femoral head. When the bone maturity was acquired all hips except two (sequelae of infections) were asymptomatic with femoral heads well covered. When discovered or suspected, this disease needs of careful follow-up. When operative treatment is necessary, we think that it has to be a pelvic surgery. We performed 4 times a triple pelvic osteotomy; 3 times a Chiari osteotomy; and twice a hip shelf arthroplasty. Those operative treatments have always been done with good results in our review.
