Thirty-four hips were observed radiographically to see the development of the femoral head. The intramedullary pressure was measured in the proximal femur before and after treatment of congenital dislocation of the hips. The intramedullary pressure in the avascular femoral head decreased more obviously than that in the normal head after treatment. A term of "IMP subtraction value" was put forward as an objective index for evaluating the development of the femoral head after treatment of congenital dislocation of the hip.
