Abstract
With advances in chemotherapy, long-term survival for childhood leukemia is improving. However, chemotherapy-induced osteonecrosis of the proximal femur remains a challenging problem. We present a case of an adolescent female with advanced osteonecrosis of the proximal femur after chemotherapy for acute lymphoblastic leukemia. She underwent an Ilizarov hip reconstruction with a subtrochanteric valgus extension osteotomy and distal femoral lengthening with varus angulation using an external fixator. At a 3-year follow-up, her symptoms and gait had markedly improved. On the basis of this preliminary report, Ilizarov hip reconstruction is a viable alternative for advanced osteonecrosis of the proximal femur in an adolescent.
