We carried out a further study of the long-term results of the cemented Exeter femoral component in patients under the age of 40 with a mean follow-up of 13.6 years (10 to 20).
We reviewed our original cohort of 104 cemented Exeter stems in 78 consecutive patients with a mean age of 31 years (16 to 39). Only one patient was lost to radiological follow-up.
A total of six patients (eight hips) had died for reasons unrelated to their surgery. There had been one further periprosthetic fracture from a fall and one fractured femoral stem. No revisions for aseptic loosening were undertaken during the whole study period. Overall, 11 hips had progressive radiolucent lines in one or more zones. The Kaplan Meier survival percentages at ten and 17 years were 97.1% (95% confidence interval (CI) 91.3 to 99.1) and 92.1% (95% CI 74.1 to 97.8) with revision for any reason as the endpoint, and 100% at both ten and 17 years with aseptic loosening (95% CI 83.8 to 100) as the endpoint. No additional hips were classified as radiologically loose.
The Exeter femoral component continues to function satisfactorily in young patients for up to 17 years after surgery. Cite this article: Bone Joint J 2017;99-B:192-8.
我们对40岁以下患者使用骨水泥型埃克塞特股骨假体的长期结果进行了进一步研究,平均随访时间为13.6年(10至20年)。
我们回顾了最初的一组病例,包括78例连续患者的104个骨水泥型埃克塞特股骨柄,患者平均年龄为31岁(16至39岁)。仅有1例患者失访。
共有6例患者(8髋)因与手术无关的原因死亡。另有1例因跌倒发生假体周围骨折,1例股骨柄骨折。在整个研究期间,未因无菌性松动进行翻修手术。总体而言,11髋在一个或多个区域出现渐进性透亮线。以任何原因翻修为终点,10年和17年的Kaplan-Meier生存率分别为97.1%(95%置信区间(CI)91.3至99.1)和92.1%(95%CI 74.1至97.8);以无菌性松动为终点,10年和17年的生存率均为100%(95%CI 83.8至100)。没有额外的髋关节被分类为影像学松动。
埃克塞特股骨假体在年轻患者术后长达17年的时间里仍能令人满意地发挥功能。引用本文:《骨与关节杂志》2017;99-B:192-8。
