Hip rotationplasty with antibiotic-loaded bone cement spacer for severe infection following limb-sparing surgery.

Abstract

Knee rotationplasty was initially proposed for the reconstruction of the knee joint in the congenital hypoplasia of the femur. Its application was extended to functional reconstruction of the knee joint after wide resection of malignant bone or soft tissue tumor around the knee. It has also been shown to salvage a failed knee-sparing surgery due to infection or the aseptic loosening of the prosthesis. Hip rotationplasty has been described as a method for the reconstuction of hip function, as well as in the knee joint, in the case of a primary malignant tumor of the proximal part of the femur in children. It has also been described as having a surgical application for the severe congenital deficiency of the proximal part of the femur to reconstruct hip and knee joints, as well as for the massive bone defect of the proximal part of the femur due to infection to mimic a functional femoral shaft. This article reports a case where the hip joint was secondarily reconstructed with hip rotationplasty after subtotal resection of the femur due to infection of the hip hemiarthroplastic prosthesis and osteomyelitis of the hip joint and femur.
