We reviewed data to determine outcomes for 21 consecutive Vancouver type B1 or type C periprosthetic fractures that we treated between 2001 and 2008 using a nickel-titanium shape-memory sawtooth-arm embracing fixator.
The study participants were 12 men and 9 women (mean age, 70.8 years; range, 42-85 years). The average duration of follow-up monitoring was 39.7 months (range, 1-78 months). In five cases, cables and screws were used for further stabilisation. No bone grafting was performed for any of the patients.
Results were satisfactory, except for one patient who died one month after surgery from a cause unrelated to arthroplasty. Bone union was achieved in the remaining 20 cases within an average of 5.25 months. No implant failures or malunions occurred in any of the patients. The average Harris hip score at the final follow-up examination was 79.3 points.
Our results show that the embracing fixator is a valid alternative treatment for Vancouver type B1 or type C periprosthetic femoral fractures.
我们回顾了数据,以确定 2001 年至 2008 年间使用镍钛形状记忆锯齿臂环抱固定器治疗的 21 例连续温哥华 B1 或 C 型假体周围骨折的结果。
研究对象为 12 名男性和 9 名女性(平均年龄 70.8 岁;范围 42-85 岁)。平均随访监测时间为 39.7 个月(范围 1-78 个月)。在 5 例中,使用电缆和螺钉进一步稳定。没有对任何患者进行骨移植。
除了一名患者因与关节置换无关的原因在手术后一个月死亡外,结果令人满意。其余 20 例患者的平均愈合时间为 5.25 个月。没有发生任何患者的植入物失败或畸形愈合。最终随访检查时的平均 Harris 髋关节评分是 79.3 分。
我们的结果表明,环抱固定器是治疗温哥华 B1 或 C 型假体周围股骨骨折的有效替代治疗方法。
