【摘要】目的初步评估Prestige LP人工椎间盘置换联合Zero-P零切迹椎间融合固定器植骨融合治疗三节段颈椎病的安全性和有效性.方法回顾分析2012年9月到2015年4月在我院行Prestige LP人工椎间盘置换联合Ze-ro-P零切迹椎间融合固定器植骨融合的三节段颈椎病患者的临床和影像学资料,采用视觉模拟评分(visual analogue scale,VAS)、日本骨科协会(Japanese orthopaedic association,JOA)脊髓功能评分及颈椎残障功能指数(neck disability index,NDI)评估患者术后临床疗效;行颈椎X线正侧位、过伸过屈位、左右侧偏位和CT三维重建检查观察患者术后假体的位置和稳定性、置换节段活动度和异位骨化情况、融合节段植骨融合情况.结果共纳入患者24例,9例患者行单节段置换+双节段融合术,其余15例行双节段置换+单节段融合术,共植入39枚Prestige LP人工椎间盘假体和33枚Zero-P零切迹椎间融合固定器.患者VAS评分、JOA评分和NDI指数在术后历次随访较术前均有明显改善(P<0.05),置换节段活动度较术前无明显差异(P>0.05),颈椎整体活动度较术前有明显下降(P<0.05).结论Prestige LP人工椎间盘置换联合零切迹椎间融合固定器Zero-P植骨融合的三节段Hybrid手术是一种安全的可以选择的治疗多节段颈椎病的手术方式,可以有效缓解患者临床症状,最大限度保留患者颈椎节段活动度,降低植骨不融合风险和邻近节段椎间盘的应力.%Objective To evaluate the effectiveness and safety of Prestige LP cervical disc replacement combined with Zero-Profile implant system interbody fusion intreating three-level cervical spondylosis.Methods Patients who underwent three-level hybrid surgery using Prestige LP and

Zero-P between September 2012 and April 2015 were ret-rospectively analyzed,clinical and radiologic data were collected.The visual analogue score (VAS),Japan Orthopedic Association (JOA)score and neck disability index (NDI)were used to evaluate the clinical effect after surgery;cervical X-Rays and three-dimensional reconstruction CT scan were used to assess the postoperative prosthesis position and sta-bility,the replacement segment activity and heterotopic ossification,and fusion rate in fusion segments.Results 24 ca-ses were included in this study,9 patients underwent single level disc replacement+two-level interbody fusion,15 pati-etns underwent double-level disc replacement+single level interbodyfusion.39 Prestige LP artificial disc prosthesis and 33 Zero-P zero profile impalnts were impalnted at last.The VAS score,JOA score and NDI index at the final follow-up were significantly improved compared with that pre operation (P<0.05),no significant difference was found concern-ing the replacement segment range of motion between the final follow-up and preoperative (P>0.05),the overall cervi-cal range of motion decreased significantlycompared with preoperative (P<0.05).Conclusion Hybrid surgery of Pres-tige LP cervical disc replacement combined with Zero-Profile interbody fusion may be a safe and effective option for the treatment of three-level cervical spondylosis.It can effectively relief the clinical symptoms,maintain cervical segmental range of motion,reduce therisk of nonfusionand decrease the adjacent segmental intervertebral disc stress.
