title: Total hip arthroplasty in osteopetrosis using computer-assisted fluoroscopic navigation.
abstract: Hybrid total hip arthroplasty with computer-assisted fluoroscopic navigation was performed on a patient with osteoarthritis due to an autosomal dominant form of osteopetrosis. The surgical procedures were difficult because the bone was extremely hard and brittle with obliteration of the medullary cavity. Especially, preparation of a femoral canal for the stem was technically challenging and required changes from a conventional surgical procedure. Therefore, we used a computer-assisted fluoroscopic navigation system to create the femoral cavity for the stem, and an accurate placement of the prosthesis was achieved. Navigation guidance can be a useful tool when performing arthroplasty in patients with hip osteoarthritis associated with osteopetrosis.
