Abstract:
Objective To explore the function and clinical effect of automatic nerve retractor in micro-endoscopic discectomy.Methods From August 2009 to December 2010,350 patients with lumbar disc hemiation were treated by micro-endoscopic discectomy,including 196 males and 154 females,aged from 17 to 68 years (average,42 years).Three cases were at L1-2,8 at L2-3,12 at L3-4,186 at L4-5 and 141 at L5S1.The automatic nerve retractor was used in all micro-endoscopic discectomy.The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate clinical outcomes.Results All patients were followed up for 6 to 16 months (average,9 months).The mean VAS score decreased from preoperative 8.79±1.15 to 3.80±1.14 3 months after operation and 3.65±1.14 6 months after operation.The mean ODI score decreased from preoperative 78％±1.71％ to 28％±1.72％ 3 months after operation and 28％±1.88％ 6 months after operation.Postoperative VAS and ODI scores decreased significantly compared with those before operation.The VAS and ODI scores 6 months after operation were not significantly improved compared with those 3 months after operation.No spinal cord and nerve root injury and epidural hematoma formation occurred in all cases.Conclusion In micro-endoscopic discectomy,the automatic nerve retractor can help the operator obtain effective exposure,protect nerves from injury,alleviate workload of the operators,therefore it has a great clinical application value.
