ABSTRACT
ABSTRACT

Objectives:

The purpose of this study was to compare union rates for isolated subtalar arthrodesis with and without the use of bone grafts or bone graft substitutes.

Methods:

We retrospectively reviewed 135 subtalar fusions with a mean follow-up of 18 ± 14 months. The standard approach was used for all surgeries. Graft materials included b-tricalcium phosphate, demineralized bone matrix, iliac crest autograft and allograft, and allograft cancellous chips. Successful subtalar fusion was determined clinically and radiographically.

Results:

There was an 88% (37/42) union rate without graft use and an 83% (78/93) union rate with bone graft use. Odds ratio of union for graft versus no graft was 0.703 (95% CI, 0.237-2.08). The average time to union in the graft group was 3 ± 0.73 months and 3 ± 0.86 in the non-graft group, with no statistically significant difference detected (p = 0.56).

Conclusion:

Graft use did not improve union rates for subtalar arthrodesis. Level of Evidence IV, Case Series.
RESUMO
RESUMO

Objetivos:

O propósito deste estudo foi comparar as taxas de união de artrodese subtalar isolada com e sem uso de enxertos ósseos ou seus substitutos.

Métodos:

Revisamos retrospectivamente 135 fusões subtalares com seguimento médio de 18 ± 14 meses. A via de acesso padrão foi utilizada em todas as cirurgias. Os enxertos utilizados incluíram fosfato b-tricálcico, matriz óssea desmineralizada, autoenxerto e aloenxertos da crista ilíaca e aloenxerto de lascas de osso trabecular. A fusão subtalar bem-sucedida foi determinada clínica e radiograficamente.

Resultados:

Verificou-se uma taxa de união de 88% (37/42) sem uso de enxerto e de 83% (78/93) com enxerto ósseo. A análise da razão de chances (odds ratio) de união óssea para enxerto e não enxerto foi 0,703 (IC 95%, 0,237-2,08). O tempo médio de união no grupo com enxerto foi de 3 ± 0,73 meses e 3 ± 0,86 no grupo sem enxerto, sem detecção de diferença estatisticamente significante (p = 0,56).

Conclusão:

O uso de enxerto não melhorou as taxas de união na artrodese subtalar. Nível de Evidência IV, Série de Casos.
