Application of the Original Method to Mobilize Dural Structures for Epidural Fibrosis of the Lumbar Spinal Canal in Reoperations

Abstract

To compare the efficacy of classical and original methods of meningoradiculolysis for epidural fibrosis of the lumbar spinal canal. Material and Methods. The study included 63 patients who underwent reoperation of the lumbar spine. Patients were randomly divided into two groups using a computer program: original method of meningoradiculolysis was performed in Group I (n = 32), and classical-in Group II (n = 31). Results. The treatment results were evaluated up to 3 months after surgery. Good results amounted to 38.9 % in Group I and to 21.6 % in Group II (p < 0.05). In group II, a punctate injury to the dural sac occurred in 3 patients, which led to postoperative liquorrhea in one case, and temporary or permanent increase in neurological deficit was observed in four cases. Conclusion. The modified method of meningoradiculolysis is technically more valid and safe in performing repeated interventions for epidural fibrosis in the lumbar spine.
