title: Fibular strut grafting for fibrous dysplasia of the femoral neck.
abstract: When fibrous dysplasia affects the femoral neck, normal bone is replaced by fibro-osseous dysplastic bone that is both mechanically weakened and biomechanically abnormal. Surgical management is recommended for persistent pain, progressive deformity, or impending fracture. Surgical options include curettage and cancellous bone grafting, osteotomy and nail-plate fixation, intramedullary rodding, and cortical bone grafting. We present the case of a patient with a painful, dysplastic lesion of the femoral neck who underwent cortical bone grafting using dual fibular strut grafts. To ensure long-term graft incorporation, the fibular cortical grafts bridged the lesion in the femoral neck and were securely anchored to the normal bone of the lateral femoral cortex and a head of the femur. No supplemental internal fixation was required. The biological basis for success of the fibular strut grafting procedure is that creeping substitution of the cortical graft necrotic bone does not replace the interstitial lamellae, which persist to lend structural support. Fibular strut grafting is an excellent procedure for fibrous dysplasia of the femoral neck.
