(A) A 35-year-old male patient with sequelae of LCPD of the left hip is shown. His hip typically showed a high-riding trochanter, a short neck with varus configuration, and (B) a mushroom-shaped head with an asphericity in the AP direction. After relative femoral neck lengthening (C), the superior and (D) anterior offset was corrected and the greater trochanter refixated in an advanced position to improve the lever arm of the abductor muscles.
