Fig 1
Three positioning Kirschner wires (3 mm in diameter, 100 mm long) were fixed into the top greater trochanter of the femur, as well as 40- and 60-mm below it. A 5-mm glass ball was placed in the femoral head as the target spot for decompression. A. Fixation of the Kirschner wires into the femur. B. The femoral specimen with the three Kirschner wires. C.
