We performed a study to provide an evaluation of the posterior lumbar interbody fusion [PLIF] in which carbon fiber cages were used. We evaluated the fusion outcome and the clinical results.
this study, 30 consecutive patients were evaluated. They were operated between April 2003 and January 2005. Clinical outcome was assessed using the Prolo scale. Fusion results were interpreted by the criteria defined by Brantigan and Steffee. The median follow-up period was 18 months. The fusion rate was 89%. Overall, 67% of the patients were satisfied with their outcome and would undergo the same operation again. Based on the results of the Prolo scale, however, in only 39% of the patients, excellent or good results were achieved.46% of the work-eligible patients resumed their working activity. Clinical outcome and return-to-work status were significantly associated with socioeconomic factors such as preoperative employment [p = 0.03], compensation issues [p = 0.001], and length of preoperative sick leave [p = 0.01]. Radiographically demonstrated fusion was not statistically related to clinical outcome [p = 0.2]. The results show that the procedure is safe and effective. Carbon cage gives better fusion on radiology, but no difference in the clinical outcome. Carbon cage use precludes complications associated with iliac bone harvesting
