Improvements in materials, components, and surgical techniques in cementless total hip arthroplasty are resulting in improved femoral stem fixation through bony ongrowth or ingrowth. While improved femoral stem fixation is one reason for the current excellent total hip survivorship, indications for stem removal such as infection, implant fracture, or osteolysis remain. A commonly used technique for fully ingrown femoral stems is an extended trochanteric osteotomy which can result in comminuted fractures of the proximal femur during stem removal requiring additional fixation. Therefore, a novel hip stem removal was developed to facilitate removal of these well-ingrown stems without the need for an extended trochanteric osteotomy. This study describes the removal system and surgical technique and presents a case series of successfully removed ingrown stems.
非骨水泥型全髋关节置换术中材料、组件及手术技术的改进，正通过骨长入或骨内生长实现股骨柄固定的改善。虽然股骨柄固定的改善是当前全髋关节出色生存率的一个原因，但诸如感染、植入物骨折或骨溶解等需要取出股骨柄的情况仍然存在。对于完全骨内生长的股骨柄，一种常用技术是大转子延长截骨术，这可能导致在取出股骨柄时近端股骨粉碎性骨折，需要额外固定。因此，研发了一种新型髋关节股骨柄取出方法，以便在无需大转子延长截骨术的情况下取出这些牢固骨内生长的股骨柄。本研究描述了取出系统和手术技术，并展示了一系列成功取出骨内生长股骨柄的病例。
