Abstract：Objective To analyze the curative effect of microsurgery assisted by Caspar expandable channel system on lumbar disc herniation. Methods Thirty patients with lumbar intervertebral disc herniation were treated by microsurgery assisted by Caspar expandable channel system. The effects of the operation were assessed by Japanese Orthopaedic Association Scale (JOA) and Visual Analogue Scale(VAS)1,3,6 and 12 months after the surgery and the final results were evaluated by Macnab classification.Results The operations were successfully completed in all the patients. There were no cerebrospinal fistulae after the repair of spinal dura mater which was intraoperatively ruptured in 2 patients. JOA scores were significantly higher 1, 3, 6 and 12 months after the operation (P<0.05),and VAS scores were significantly lower 1,3,6 and 12 months after the operation than those before the operation(P<0.05).The excellent and good rate of Macnab functional classification was 96.7% (29/30). Conclusion The microsurgery assisted by Caspar expandable channel system is a safe and effective method to treat lumbar disc herniation and worthy of clinical application and spread.
