Intramedullary pressure in the proximal femur before and after treatment of congenital dislocation of the hip in children.
Intramedullary pressure in the proximal femur was measured before and after treatment of congenital dislocation of the hip. The intramedullary pressure before treatment was higher than that of the control group, and after treatment it was lower as a whole; in the close reduction group the pressure decreased as compared with the operation group. In 8 hips, stress test yielded negative results. These findings suggested the characteristics of arterial blockage may be that the potential cause of avascular necrosis of the femoral head after treatment of congenital dislocation of the hip.
