在一项前瞻性研究中，作者在1997年11月至1999年6月期间使用多孔钽整体式髋臼部件进行初次全髋关节置换术。143例年龄小于75岁的患者共进行了156例连续初次全髋关节置换术。共151个髋关节随访8 ~ 10年。术前平均Harris髋关节总评分为44.0 +/- 13.8，最后随访时增加至97.0 +/- 6.2-Lip。平均术前Oxford髋关节评分为43.3 +/- 6.5，末次随访时改善至13.9 +/- 2.3。包括Ein-Bild-Rontgen-Analyse（EBRA）数字系统在内的影像学评价显示，没有明显聚乙烯磨损、进行性透亮线、溶骨性病变、髋臼骨折或部件下沉的影像学证据。有7例（4.5%）术后并发症，均与髋臼部件无关。
In a prospective study, the authors used a porous tantalum monoblock acetabular component for primary total hip arthroplasty between November 1997 and June 1999. A total of 156 consecutive primary total hip arthroplasty were done in 143 patients younger than 75 years. A total of 151 hips had a follow-up time from 8 to 10 years. The average preoperative total Harris hip score of 44.0 +/- 13.8 increased to 97.0 +/- 6.2 at the latest follow-Lip. The average preoperative Oxford hip score of 43.3 +/- 6.5 improved to 13.9 +/- 2.3 at the latest follow-up. Radiographic evaluation including the Ein-Bild-Rontgen-Analyse (EBRA) digital system showed no radiographic evidence of gross polyethylene wear, progressive radiolucencies, osteolytic lesions, acetabular fracture, or component Subsidence. There were 7 (4.5%) postoperative complications all unrelated to the acetabular component.
