The effect of mitomycin C in reducing epidural fibrosis after lumbar laminectomy in rats.

Object: Extensive epidural fibrosis after lumbar spine surgery might be an important underlying cause of failed-back syndrome. Based on previously obtained data, the effect of mitomycin C (MMC) in a concentration of 0.1 mg/ml on spinal epidural fibrosis in a rat laminectomy model was investigated in a large series.
