We report 3 cases of periprosthetic fractures after total knee replacement treated with Ilizarov external fixator (Smith and Nephew plc, Memphis, Tenn) and a follow-up of at least 3 years. We used 2 rings in the supracondylar area distal to the fracture and 3 half pins proximally in all our cases leaving the knee free to move. In one patient apart from the 2-ring frame placed distal to the fracture site the fixator included another ring frame placed proximally just below the 3 half pins. Uncomplicated fracture healing with lower extremity excellent alignment was achieved in 12 weeks after surgery. In periprosthetic femoral fractures, especially in elderly patients, Ilizarov external fixator is a treatment option which provides stable fixation, prompt postoperative mobilization, and has no major complications.
我们报告了 3 例全膝关节置换术后使用伊里扎洛夫外固定架（Smith and Nephew plc，田纳西州孟菲斯）治疗的假体周围骨折，随访时间至少 3 年。我们在所有病例中均使用 2 个环形架在骨折远端的髁上区域，3 个半针在近端，使膝关节可以自由活动。在 1 例患者中，除了放置在骨折部位远端的 2 个环形框架外，固定器还包括另一个环形框架，放置在近端，刚好在 3 个半针下方。手术后 12 周，下肢对线良好，骨折愈合顺利。对于假体周围股骨骨折，特别是老年患者，伊里扎洛夫外固定架是一种治疗选择，它提供稳定的固定，术后可立即活动，且没有重大并发症。
