摘要
目的探讨应用颈椎动态稳定器(DCI)治疗颈椎间盘突出症的安全性及有效性。方法对16例颈椎间盘突出症患者均行经前路颈椎间盘切除、椎管减压后DCI植入术,采用VAS、PSI评分评价术前、术后1周、术后3个月及6个月的神经功能恢复情况。术前、术后常规X线片检查,Cobbs’法测量患者术前和术后C2到C7植入节段和植入邻近节段的运动范围。结果末次随访,患者术后上肢VAS评分平均改善4.9分,颈部VAS评分平均改善4.5分,术后患者平均PSI评分为1.6分。颈椎C2到C7的活动范围平均减少7.01°±6.65°(P<0.05);术后植入节段椎间隙的平均活动范围减少0.91°±0.57°(P<0.05);术后邻近节段的活动范围平均减少0.68°±0.38°(P>0.05)。手术有效率为100%。结论应用颈椎动态稳定器治疗颈椎间盘突出症,在保留颈椎一定生理活动度的情况下,并未增加手术邻近节段活动度,维持了颈椎稳定性,早期临床效果较好。
Objective To investigate the safety and efficiency of dynamic cervical implant（DCI）internal fixation to treat intervertebral disc degeneration.Methods There were sixteen patients who suffered herniation of cervical disc,each received DCI implantation.Use VAS and PSI scoring method to asscess neurofunctional recovery preoperatively and one week,three months,six months after operation.Routinely,the patients accepted X-ray examination preoperatively and postoperatively.We used Cobb＇s measurement to measure the ROM of C2-C7,implant segment and adjacent segment pre and postoperation.Results Last follow-up,the average VAS score improved 4.9 and 4.5 at upper limbs and neck,respectively.The average PSI score was 1.6.The average ROM of C2-C7 decreased 7.01°±6.65°（P0.05）.The average ROM of implant segment decreased 0.91°±0.57°（P0.05）.The average ROM of adjacent segment decreased 0.68°±0.38°（P0.05）.The effective rate of operation was 100%.Conclusion Using dynamic cervical implant to treat intervertebral disc herniation retain the cervical biomechanical movement in some degree,while not increasing the ROM of adjacent segments.It can maintain the cervical stability,also has a good clinic outcome.
