The blue pin represents the obturator externus; the green pin represents the glutes minimus. The yellow trapezoid shape indicates the conjoint tendon; the blue trapezoid shape indicates the obturator externus. The femoral neck (Fn), piriformis (Pf), conjoint tendon (Cj), and the elevation of the femoral neck (blue rectangle) are shown before the obturator externus (Oe) was resected in a. The elevation of the femoral neck (blue rectangle) is shown after the obturator externus (Oe) was resected in b
