We reviewed the outcome of 905 femoral revisions performed at our institution between June 1980 and August 2006 using extensively porous-coated, cylindrical stems. A total of 20 femoral rerevisions were identified, including 12 for aseptic loosening, 4 for infection, 3 for stem fracture, and 1 in conjunction with a periprosthetic femur fracture. All stem rerevisions occurred within the first 10 years after surgery. Kaplan-Meier survivorship, using stem rerevision for any reason as an end point, was 97.5% +/- 1.3% (95% confidence intervals) at 5 years, declined to 95.9% +/- 1.9% at 10 years, and remained constant thereafter. With long-term follow-up, extensively porous-coated, cylindrical stems used for femoral revision continue to demonstrate excellent survivorship.
我们回顾了1980年6月至2006年8月间在本机构使用广泛多孔涂层圆柱形柄进行的905例股骨翻修手术的结果。共确定了20例股骨再次翻修，其中12例为无菌性松动，4例为感染，3例为柄部骨折，1例合并假体周围股骨骨折。所有柄部再次翻修均发生在手术后的前10年内。以任何原因进行柄部再次翻修为终点的Kaplan-Meier生存率，5年时为97.5%±1.3%（95%置信区间），10年时降至95.9%±1.9%，此后保持稳定。经过长期随访，用于股骨翻修的广泛多孔涂层圆柱形柄继续显示出优异的生存率。
