La alternativa acero inoxidable o titanio en la fusión vertebral.
Evaluación sobre el efecto potencial que ejercerían ambos materiales sobre el resultado postquirúrgico.
El autor comparó los resultados clínicos de las fusiones lumbosacras en 368 pacientes en los que se utilizó implantes de acero inoxidable y 271 (todos posteriores a 1975) con materiales de titanio.
Los resultados se evaluaron a los 3, 6 y 12 meses y nuevamente a los 2 años. Los problemas relativos al implante (rupturas y aflojamientos), fueron equivalentes. El índice de fusión a los 6 meses fue del 67% para el grupo acero inoxidable y de 63% en el grupo titanio. No obstante, ambos grupos mostraron implantes estables a los 2 años.
Frente a estos resultados, el autor sugiere que los tornillos de titanio podrían inicialmente retardar la fusión, pero dada la paridad del índice de complicaciones, concluye en la necesidad de un seguimiento más prolongado.
