Uncemented tantalum acetabular components were introduced in 1997. The purpose was to determine the 2- to 10-year results with this implant material in primary total hip arthroplasty. Our registry identified all primary total hip cases with porous tantalum cups implanted from 1997 to 2004. Clinical outcomes and radiographs were studied. 613 cases were identified. Seventeen percent of patients were lost to follow-up. Twenty-five reoperations were performed (4.4%). Acetabular cup removal occurred in 6 cases (1.2%). No cups were revised for aseptic loosening. Incomplete radiolucent lines were found on 9.3% of initial postoperative radiographs. At 2 years, 67% had resolved. Zero new radiolucent lines were detected. Two- to 10-year results of porous tantalum acetabular components for primary total hip arthroplasty demonstrate high rates of initial stability and apparent ingrowth.
非骨水泥钽髋臼组件于1997年推出。目的是确定这种植入材料在初次全髋关节置换术中2至10年的结果。我们的登记处识别出了1997年至2004年植入多孔钽杯的所有初次全髋关节病例。对临床结果和X线片进行了研究。共识别出613例病例。17%的患者失访。进行了25次再次手术（4.4%）。6例（1.2%）进行了髋臼杯取出。没有因无菌性松动而翻修髋臼杯。术后初期X线片上发现9.3%有不完全透光线。2年后，67%的透光线消失。未检测到新的透光线。多孔钽髋臼组件用于初次全髋关节置换术的2至10年结果显示出高初始稳定性和明显的骨长入率。
