[Clinical analysis in treating lumbar intervertebral disc herniation with nucleus pulposus resection through small incision and lamina fenestration]

Abstract

Objective: To analyze effect of treatment of lumbar intervertebral disc herniation with nucleus pulposus resection through small incision and lamina fenestration,and to explore operative advantage and mattars needing attention.

Methods: Ninety-six patients with lumbar intervertebral disc herniation, including 48 males and 48 females with an average age of 46.4 years (ranging for 16-75 years) and an average course of 5 years (ranging from 1 month to 30 years), were treated with nucleus pulposus resection through small incision and lamina fenestration. The clinical effects were analyzed according to JOA scoring criteria of lower back pain.

Results: All patients were followed up from 6 months to 3.5 years with an average of 1.2 years. According to JOA scoring criteria, 34 cases obtained excellent result, 55 good, fair 7. The rate of excellent and good was 92.71% and the mean improvement rate was 54.53%.

Conclusion: Nucleus pulposus resection through small incision and lamina fenestration can obtain satisfactory outcome in treating lumbar intertebral disc herniation. The incidence of lumbar instability and postoperative complications were low. It is one of the better method for the treatment of lumbar intertebral disc herniation.
