对1例常染色体显性骨硬化症引起的骨关节炎患者进行了计算机辅助透视导航的混合型全髋关节置换术。手术操作困难，因为骨非常硬和脆，髓腔闭塞。特别是，为股骨柄准备股骨髓腔在技术上具有挑战性，需要改变传统的外科手术。因此，我们使用计算机辅助荧光镜导航系统为股骨柄创建股骨腔，并实现了假体的准确放置。在对骨硬化症相关髋关节骨关节炎患者进行关节置换术时，导航引导是一种有用的工具。
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.
