多孔金属钽髋臼在全髋关节置换术后髋臼翻修中的应用

人工全髋关节关节置换术（total hip arthroplasty，THA）是20世纪最成功的外科治疗手段之一，它极大程度改善了严重髋关节伤病患者的生活质量。随着第1例全髋关节置换手术的成功，接受全髋关节置换的患者不断增加，在美国每年约有250000例患者行髋关节手术，而THA大约为髋关节手术量的17．5％。近年来THA在我国发展迅速，每年接受人工髋关节置换手术有50000例左右，

Application of porous tantalum in acetabular revision after total hip arthroplasty

To review the application effects of the porous tantalum acetabular cup in acetabular revision for acetabular failure after total hip arthroplasty ( THA ). The related literatures about the characteristics of porous tantalum and its application in acetabular revision in recent 10 years were retrieved from China National Knowledge Internet ( CNKI ) and PubMed databases, and a review was made. The porous tantalum acetabular cup had unique high porosity, low elasticity, high friction coefficient and good function to promote bone ingrowth inwardly. Good clinical results could be obtained using the porous tantalum acetabular cup in acetabular revision for patients with initial fixation failure using the artificial acetabular cup. In acetabular revision, the porous tantalum acetabular cup can provide superior mechanical stability, with good early and medium-term results.
