OBJECTIVE
To evaluate a mixed technique of acetabular reconstruction, which uses trabecular metal in the form of tantalum augments associated with lyophilized bovine xenograft.
METHODS
Fifteen patients were evaluated prospectively, who underwent acetabular reconstruction with impacted lyophilized bovine xenograft associated with the use of tantalum augments. The main outcome was the failure of the tantalum-bone interface.
RESULTS
The population had a mean age of 58.33 years ± 14.27; the majority was female, 80%. Of the total subjects, 66.7% were operated for failure in primary arthroplasty. The mean follow-up time was 45.2 months ± 11.39. The failure rate of the method in the period and population studied was 6.7%.
CONCLUSION
An extremely high index (93.3%) of success was observed in an average time of 45.2 months of follow-up. Data were comparable to current literature, demonstrating that the technique employed and proposed is adequate for hip reconstruction in young patients.
目的
评估一种髋臼重建的混合技术，该技术使用钽增强物形式的小梁金属与冻干牛异种移植物联合使用。
方法
对15例患者进行前瞻性评估，这些患者接受了冻干牛异种移植物打压植骨联合钽增强物的髋臼重建手术。主要观察指标是钽与骨界面的失败情况。
结果
患者平均年龄为58.33岁±14.27岁；大多数为女性，占80%。在所有受试者中，66.7%因初次关节置换失败而接受手术。平均随访时间为45.2个月±11.39个月。在所研究的时间段和人群中，该方法的失败率为6.7%。
结论
在平均45.2个月的随访时间内，观察到极高的成功率（93.3%）。数据与当前文献相当，表明所采用和提出的技术适用于年轻患者的髋关节重建。
