Figure 5: (a) Boy GMFCS 4, 8 years old, directly after the operation. Screw location relative to middle of epiphysis and trochanter not important. Enough windings of screw need to fix epiphysis. (b) Boy GMFCS 4, 19 months after surgery. Clearly recognizable varus tilt of the femoral neck and epiphyseal plate. Screws only briefly hold epiphyseal joints.
