目的 探讨广泛性轻磷灰石涂膜人工股骨干用于全髋关节置换术进行中期效果的研究.方法 从1998年至2004年,共37例患者在全髋关节置换术中使用了广泛性轻磷灰石涂膜人工股骨干,研究项目包括骨内生长、松脱及翻修手术的原因、其他并发症及广泛性轻磷灰石涂膜人工股骨干的存活率.结果 平均手术年龄为62.6岁及平均术后随访为5年.在术后4年,1例(2.7%)人工股骨干因深层感染需要拆除,它当时已经是固定良好.在术后1.6年及6.3年,分别有2例(5.4%)出现无菌性松脱沉降需要做翻修术;另外有1例(2.7%)因有其他的临床问题没有翻重修术.3例松脱沉降的患者都在前14例中出现.这3例松脱患者,在X光检查中发现股骨干的尺码相对股骨较细小因而引致松脱.机械式的失败率为8.1%,81%的股骨干被分类为稳定而有骨内生长.如果端点为翻修手术及放射照片松脱,广泛性轻磷灰石涂膜人工股骨干的9年存活率分别为91.2%及93.9%.结论 广泛性轻磷灰石涂膜人工股骨干的临床效果可以与广泛性多孔涂膜人工股骨干相媲美.但是,精通手术植入的技巧需要较长时间掌握.

Objective To study the midlterm result of extensively hyclroxyapatite-coated stem in revision THA. Methods From 1998 to 2004,37 revision total hip arthroplasty using an extensively hydlroxyapatitecoated femoral stem were reviewed.Bone ingrowth,reasons for loosening and revision surgery and otlaer complications were studied.Survival analysis of the extensively hydroxyapatite coated femora stem were analyzed. Results The average age at revision was 62.6 years old.The average follow up was 5.5 years.Two stems(5.4%)were revised at 1.3 years and 6.3 years respectively because of aseptic loosening with subsidence.One stem(2.7%)had evidence of aseptic loosening with subsidence was not revised because of medical problems.Radiographs of the three loosened cases showed under-sizing of femoral stems.The mechanical failure rate Was 8.1%.Eighty-one percent of femoral stem was classified as stable with bone ingrowth.The survival of the femoral stem wag 91.2%and 93.9%at 9 years using revision surgery and radiographic loosening as endpoint. Conclusion Extensively hydroxyapatite-coated femoral stem has comparable clinical result with extensively porous-coated femoral stemHowever,the learning curve of implanting a press-fit long stem Was steep.
