[目的]总结应用ACDF联合术中颅骨牵引助推撬拨技术治疗下颈椎单节段关节突绞锁的临床效果.[方法]采用ACDF联合术中颅骨牵引助推撬拨技术治疗30例单节段下颈椎关节突绞锁患者,记录关节突关节复位所需时间、手术时间、出血量等,并定期复查X线片及CT,通过测量椎间隙高度及Bfidwell椎间融合标准评估椎间植骨融合情况,根据ASIS评级分析手术前后神经功能,根据JOA评分评估脊髓功能恢复情况.[结果]30例患者均手术顺利,关节突关节复位所需时间(2±1) min,手术时间(45±8) min,术中失血(30±5) ml.术后影像检查显示伤段100％复位,融合良好,椎体间隙高度增加.除3例患者外,其他患者术后1个月时ASIA评级显著改善.与术前相比较,术后3个月JOA评分明显改善.[结论]应用ACDF联合术中颅骨牵引助推撬拨技术能够在短时间内使关节突绞锁复位,挽救脊髓功能,长期可保持椎间高度和脊柱正常序列,椎间融合可靠,操作简单.“,”[Objective] To investigate the clinical outcome of skull traction combined with reduction by leverage during anterior cervical decompression and fusion (ACDF) for a unilateral articular process interlocking in lower cervical spine.[Methods] Thirty patients with a unilateral articular process interlocking in lower cervical spine were surgically treated with ACDF,in which intraoperative skull traction and leverage technique were used for reduction of the interlocked facet joint.The time of reduction and operation,as well as bleeding amount of were recorded.After operation,the height of intervertebral space and the intervertebral fusion were radiographically assessed by Bridwell criteria,additionally,the neurological function was evaluated by Japanese Orthopedic Association (JOA) scoring and American Spinal Injury Association (ASIA) grading.[Resuit] All of the 30 patients underwent operation successfully with an average reduction time of (2± 1) min,total operation time of (45±8) min,and blood loss of (30±5) ml.The postoperative radiographs revealed 100％ reduction and good fusion of the affected segment,associated with increased intervertebral disc height.The ASIS grades improved significantly in all patients except 3 cases at 1 month after surgery.The JOA scores also improved significantly compared with those preoperatively (P＜ 0.05).[Conclusion] During ACDF skul1 traction combined with leverage technique does reduce the locked articu1ar process quickly,which rebuild and remain the normal cervical alignment for saving neurologic function.
