Ribbed股骨柄全髋关节置换24例11年随访

[目的]观察Ribbed股骨柄髋假体全髋关节置换后的远期疗效。[方法]自1999年6月～2002年5月,采用解剖柄HA涂层Ribbed髋假体施行非骨水泥固定人工全髋关节置换126例,获平均11年4个月随访24例26髋,男14例,女10例;年龄43～68岁,平均59.4岁。术前疾病:股骨头缺血坏死13例(双侧2例),股骨颈骨折9例,髋关节发育不良2例。术后7～10d,术后6个月和每年1次随访X线片,对髋关节功能依末次随访状况行Harris评分。[结果]依末次随访Harris评价法,获85～100分16例18髋,75～84分8例8髋。轻微大腿痛1例1髋,X线片显示轻微骨吸收1例1髋,无一患髋需行翻修术。术后6个月～3年X线片显示于HA涂层部位近段骨吸收于Gruen5,6区和2,3区1例1髋。所有病例的骨锚固和松质骨、皮质骨骨密度轻度增高,显示髋假体-骨固定良好。[结论]Ribbed髋假体的初始固定能促进早期骨长入达到生物固定目标,并阻碍聚乙烯磨屑髓内迁徙致大腿痛和骨吸收,其长期疗效肯定。

Total hip replacement with Ribbed hydroxyapatite-coated femoral stem and cup component:a 24 cases report

[Objective]To investigate the long-term result of total hip replacement with a Ribbed hydroxyapatite-coated proximally femoral stem and cup component.[Method]From June 1999 to May 2002,24 cases (26 hips) with hip joint disease received cementless total hip replacement with a Ribbed hydroxyapatite-coated proximally femoral stem and cup component. There were 14 males and 10 females with the average age of 59.4 years. The disorders included avascular necrosis of the femoral head in 13 cases,femoral neck fractu...
