目的探讨单椎间隙和多椎间隙射频消融髓核成形术对山羊颈椎稳定性的影响.方法成年山羊20只,分为单椎间隙手术组(A组)、多椎间隙手术组(B组),每个手术组再分为术后24h取标本组(A1组、B1组)和术后3个月取标本组(A2组、B2组),每小组5只山羊.单椎间隙手术组行C3/4射频消融髓核成形术,多椎间隙手术组行C3/4、C4/5射频消融髓核成形术.A1组、B1组于术后24h以5F导管作为影像学测量标记拍摄山羊颈椎正、侧、动力位片(过屈、过伸位片),A2组、B2组于术后3个月以5F导管作为影像学测量标记拍摄山羊颈椎正、侧、动力位片(过屈、过伸位片).分别测量其侧位、动力位(过屈位、过伸位)片C3/4(A组)或C3/4、C4/5(B组)节段的椎间盘高度、相邻椎体间的角度位移和水平位移.结果单椎间隙组和多椎间隙组手术前后椎间盘的高度、相邻椎体的水平位移、角度位移均无明显变化,差异均无统计学意义(P＞0.05).结论单椎间隙和多椎间隙射频消融髓核成形术对山羊颈椎的影像学稳定性无影响,射频消融髓核成形术不会造成山羊颈椎不稳.

Objective To evaluate the influence of the single and multiple intervertebral space radiofrequency ablation nucleoplasty on the sheep cervical spine stability.Methods Twenty healthy adult sheep were randomly divided into single intervertebral space operation group (A group )and multiple intervertebral space operation group ( B group ),each group was subdivided into postoperative 24 hours group ( A1,B1 group ) and post- operative 3 months group ( A2,B2 group),each group had five sheep.Radiofrequency ablation nucleoplasty on sheep C3/4 in the single intervertebral space operation group or C3/4,C4/5 in multiple intervertebral space operation group.Preoperative cervical vertebrae roentgenograms from all samples in neutral,lateral,hyperextension and hyperflexion positions were collected,and 5F pipe was used as the survey mark of ieonography.For the postoperative 24 hours group( A1,B1 group ),the roentgenograms were collected postoperatively 24 hours later,while for post- operative 3 months group (A2,B2 group),they were collected postoperatively 3 months later.The height of operative intervertebral space,horizontal and angular displacement of neighboring vertebral body were measured respectively.Results The roentgenograms showed no any obvious decrease in the height of intervertebral disc and no any increase in horizontal and angular displacement of neighboring vertebral body were observed in single intervertebral space operation group (A group) and multiple intervertebral space operation group (B group ).There was no significant difference between pre - operation and post - operation in them ( P ＞ 0.05 ).Conclusions The stability of the sheep cervical spine had not been affected by the single or multiple intervertebral space radiofrequency ablation nucleoplasty on the basis of X-ray results.The radiofrequency ablation nucleoplasty had no influences on the stability of sheep cervical vertebrae.
