STUDY DESIGN: Experimental animal study. OBJECTIVE: The authors conducted a study to determine the effectiveness of waxed paper in preventing postlaminectomy epidural fibrosis in rats. SUMMARY OF BACKGROUND DATA: Extensive epidural fibrosis after lumbar surgery may be the underlying cause in most cases of failed back surgery syndrome. Various materials have been used to prevent epidural fibrosis, but only moderate success has been shown. METHODS: Laminectomies were performed at the fourth lumbar vertebra (L-4) in 30 rats. Waxed paper or Gore-Tex was applied in a blinded fashion to the operative sites. In the control group, only the L-4 laminectomy was performed. The rats were killed 28 days after surgery. RESULTS: The extent of epidural fibrosis was evaluated by histologic analysis. There was a meaningful statistical difference among the waxed paper group and the Gore-Tex group compared with the control group, but there was no difference when the effectiveness of waxed paper was compared with that of Gore-Tex. CONCLUSIONS: In this experimental model, the waxed paper applied locally effectively reduced epidural fibrosis, completely avoided dural adherence, and induced no side effects.
