Abstract
in English, Portuguese

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.

Objetivo: Avaliar uma técnica mista de reconstrução acetabular que usa metal trabecular na forma de cunhas de tântalo associadas com enxerto ósseo bovino liofilizado.

Métodos: Foram avaliados prospectivamente 15 pacientes submetidos à reconstrução acetabular com enxerto bovino liofilizado impactado associado ao uso de cunhas de tântalo. O principal desfecho avaliado foi a falha da interface tântalo-osso.

Resultados: A população apresentou idade média de 58,33 anos ± 14,27, a maioria do sexo feminino 80%. Do total, 66,7% foram operados por falha da artroplastia primária. O tempo médio de seguimento foi de 45,2 meses ± 11,39 meses. A taxa de falha do método no período e na população estudada foi de 6,7%.

Conclusão: Observou-se um índice extremamente elevado (93,3%) de sucesso em um tempo médio de 45,2 meses de seguimento. Os dados são comparáveis à literatura corrente, o que demonstra que a técnica empregada e proposta é adequada para reconstrução de quadril em pacientes jovens.
