颈椎前路减压植骨与植骨加ORION钢板治疗脊髓型颈椎病的比较

目的　探讨分析颈椎单纯前路减压植骨与减压后外加自锁钢板内固定术治疗脊髓型颈椎病的临床疗效。方法　 64例脊髓型颈椎病患者 ,经颈前路减压 ,30例取自体髂骨移植 ,34例采用植骨 ,并行带锁钢板固定。同时对结果进行临床及影像学分析。结果　随访 0 .5～ 3年 ,平均 2 .3年。两组所有病例术后 1 2周骨性愈合 ,均无植骨块移位、脱出或陷入 ,无钢板、螺钉折断、滑脱等并发症。单纯植骨组和植骨 自锁钢板组两者手术有效率无显著性差异。颈椎ORION自锁钢板操作简便安全。结论　脊髓型颈椎病可采用前路减压植骨融合 ;加用ORION带锁钢板内固定 ,能增加稳定性 ,应用前景良好。

Comparison of Anterior Decompression and Interbody Fusion with and without ORION Locking Plate for Cervical Spondylotic Myelopathy

Purpose To analyze the clinical and radiological outcomes of anterior decompression and interbody fusion with and without an additional locking plate fixation for cervical spondylotic myelopathy. Methods Sixty four cases of cervical spondylotic myelopathy(CSM) patients were studied.30 cases were treated with anterior decompression and auto iliac bone graft.Other 34 cases were implanted with additional cervical spine ORION locking plate fixation.The outcomes was assessed by clinical criteria and radiographs of the cervical spine. Results The period of postoperative follow up studies varied from 0.5 to 3 years with an ave rage of 2.3 years.A solid fusion was obtained in all cases of the two groups within 12 weeks postope ratively.There is no motility,separation or falling of the interbody bone in all cases.No complications occurred,such as breaking of the plate and screw.The effective rate of operation with and without locking plate showed no signigicant differences.ORION locking plate had the characteristics of simple and safety. Conclusions CSM can be treated by anterior decompression and interbody fusion.ORION locking plate fixation could supply highly intrinsic stability,and its application has shown good prospects.
