摘　　要：目的:探讨颈后路术后早期(术后3个月)发生神经功能恶化患者长期随访的预后情况及相关危险因素。方法:回顾性分析17例在2006年1月~2012年12月间在我科接受保留一侧肌肉韧带复合体的颈后路椎管扩大成形术后早期神经功能恶化(术后3个月随访时mJOA评分较术前下降≥1分)的患者,以术后10年随访时m JOA评分是否恢复至术前水平将患者分为未恢复组(n=5)及恢复组(n=12),收集两组患者的基线信息、围术期资料及术后3个月、1年和10年时的改良日本骨科协会(modified Japanese Orthopaedic Association,mJOA)评分、颈椎功能障碍指数(neck disability index,NDI)、视觉模拟量表(visual analog scale,VAS)评分和影像学数据[包括Cobb角、颈椎活动度(range of motion,ROM)以及C2-C7矢状面轴向距离(sagittal vertical axis,SVA)]。比较两组患者历次随访时上述指标的差异并进行回归分析,并比较发生早期神经功能恶化时两组患者mJOA评分不同项目是否存在差异。结果:未恢复组患者合并颈椎后纵韧带骨化(ossification of longitudinal ligament,OPLL)比例明显高于恢复组,两组间在年龄、性别、体重指数、合并症、合并脊髓T2高信号、合并发育性颈椎管狭窄等基线信息以及围术期手术时间、出血量、住院时间等均无统计学差异(P>0.05)。未恢复组中1例患者发生脑脊液漏及C5神经根麻痹,恢复组中1例患者发生脑脊液漏,两组间差异无统计学意义。在术后3个月发生早期神经功能恶化后,所有患者完善影像学检查后未见减压不充分,均未行二期手术治疗。未恢复组与恢复组患者术前mJOA评分分别为13.30±2.46分及14.71±1.41分,差异无统计学意义。在发生早期神经功能恶化后,恢复组患者术后1年随访mJOA评分较术后3个月随访明显改善且与术前水平无显著性差异,术后10年随访时显著性高于术前及历次随访;未恢复组患者术后1年和10年随访时mJOA评Objectives:To explore the long-term follow-up prognosis and risk factors in patients with neuro-logical function deterioration after expansive open-door laminoplasty at early postoperative stage(within 3 months).Methods:A retrospective analysis was conducted on 17 patients who experienced neurological func-tion deterioration(the mJOA score decreased by≥1 point at postoperative 3 months′follow-up compared with that before operation)at early stage after receiving laminoplasty with the preservation of unilateral muscle-lig-ament complex in our department between January 2006 and December 2012.The patients were divided into non-recovery group(n=5)and recovery group(n=12)based on whether the mJOA score of one patient recovered to one′s preoperative level at postoperative 10-year follow-up.The baseline data,perioperative information,postoperative 3-month,1-year and 10-year mJOA score,neck disability index(NDI)score,and visual analog scale(VAS)score,as well as the imaging data[Cobb angle,range of motion(ROM)of the cervical spine,and sagittal vertical axis(SVA)of C2-C7]were collected and compared for regression analysis.The differences be-tween different mJOA categories involved between the two groups were also compared.Results:The proportion of patients with ossification of longitudinal ligament(OPLL)in the non-recovery group was significantly higher than that in the recovery group.There were no statistically significant differences between the two groups in baseline information such as age,gender,BMI,comorbidities,spinal cord T2 high singnal intensity and devel-opmental cervical canal stenosis,as well as perioperative information such as operative time,blood loss and the length of hospital stay(P>0.05).One patient in the non-recovery group had experienced cerebrospinal fluid leakage and C5 nerve root palsy and 1 patient in the recovery group had experienced cerebrospinal fluid leakage,and the difference wasn′t with statistical significance between the two groups.After neurological dete-rioration occurred within
