INTRODUCTION
Modem indications for use of cemented or uncemented implants in revision hip arthroplasty are comparable. The use of bone cement provides predictable short term results, but the lack of osteointegration deteriorates its long term durability. Uncemented implants undergo osteointegration, but reduced contact with host bone may cause early loosening. Modular porous tantalum implants are highly osteointegrative, and the availability of bone stock augments increases the versatility of this system.
MATERIAL AND METHODS
The study group consisted of 20 patients (21 hips) who underwent a revision hip arthroplasty using Trabecular Metal acetabular revision system. The follow-up period was between 7 and 31 months (average 20 months). All patients were evaluated with HHS and conventional radiography.
RESULTS
The mean HHS increased form40.45 (range 18.74-56.65) preoperatively to 78.8 (56.5-96) at the last follow-up. No mechanical failures, nor septic complications were noted.
引言
在翻修髋关节置换术中使用骨水泥型或非骨水泥型植入物的现代指征是相当的。骨水泥的使用可提供可预测的短期效果，但缺乏骨整合会降低其长期耐用性。非骨水泥型植入物会发生骨整合，但与宿主骨的接触减少可能导致早期松动。模块化多孔钽植入物具有高度的骨整合性，骨储备增加提高了该系统的通用性。
材料与方法
研究组由20例患者（21髋）组成，这些患者接受了使用小梁金属髋臼翻修系统的翻修髋关节置换术。随访期为7至31个月（平均20个月）。所有患者均采用髋关节 Harris 评分（HHS）和传统放射学检查进行评估。
结果
平均HHS从术前的40.45（范围18.74 - 56.65）提高到末次随访时的78.8（56.5 - 96）。未观察到机械故障和感染并发症。
