Desde finales de 1992 hemos venido realizando artrodesis intersomática lumbar, inicialmente añadiendo fusión posterolateral instrumentada con tornillos pediculares y, posteriormente artrodesis intersomática sola con cilindros de titanio y hueso autólogo.
Queremos presentar nuestros resultados en un grupo de 52 pacientes con seguimiento que oscila desde los 4 años y medio hasta los seis meses. Para valorar los resultados hemos usado la, escala de Prolo (Prolo Functional Economic Outcome Rating Scale) obteniendo un alto porcentaje (92%) de resultados satisfactorios.
El porcentaje de fusión, aun considerando la dificultad de su valoración por el artefacto radiológico provocado por los cilindros, es igualmente muy elevada cercana al 100%).
Concluimos que la artrodesis intersomática con cilindros es una intervención quirúrgica con la que se obtienen resultados muy favorables si se siguen unos criterios clínicos estrictos en su aplicación y una correcta técnica quirúrgica.
Since late 1992 we started performing posterior lumbar interbody fusions together with pedicular screws and intertransverse fusion. Later on we decided to use posterior lumbar interbody fusions with titanium cages and autologous bone.
We are presenting our results with a group of 52 patients with 6 months to 4 and a half years of follow-up.
We have used the Prolo Functional Economic Outcome Rating Scale to evaluate our results, obtaining a high percentage (92%) of satisfactory results. The fusion's percentage was also very high, although we express the difficulty to evaluate the fusion grade considering the X-ray artifact produced by the cages.
We conclude that PLIF with cages it is a surgical procedure with a high rate of success if we establish clearly the clinical criteria for its application and perform correctly the surgical technique.
