短期佩戴围领对颈椎术后活动度与轴性症状的影响

Influence on cervical axial symptom and the rang of motion caused by short-time duration of wearing a cervical collar

目的分析颈椎后路术后轴性症状的成因及围领佩戴时间对颈椎活动度及轴性症状的影响。方法2010年1月至2011年9月行颈椎单开门椎管扩大成形术36例为实验组，术后颈围领制动4周。2009年1月至2011年1月颈椎单开门术后22例为对照组，术后围领固定8～12周。并分别对两组患者的术后神经症状改善率、颈椎活动度及轴性症状进行对比。结果两组患者单开门术后以JOA评分缓解率差别无统计学意义。但颈椎总活动度的维持较对照组增加（P〈0．05）。同时术后轴性症状评分与对照组差异有统计学意义（P〈0．05）。结论颈椎单开门术后短期佩戴围领在取得良好神经缓解率的同时颈椎活动度得到了较好的维持，轴性症状明显减轻。

Objective To assess the cause of axial symptom and the degree of influence on cervical range of motion and axial symptom caused by the different duration of wearing a cervical collar in patients undergoing open-door laminoplasty. Methods From January 2010 to September 2011, a total of thirty-six patients underwent open-door laminoplasty and wore a cervical collar for 4 weeks .All of them were classified as group A. As the same, from January 2009 to January 2011 twenty-two patients wearing a cervical collar for 8-12 weeks were classified as group B. In both groups the neurologic recovery rate, cervical range of motion and axial symptom were recorded and compared. Results There was no significant difference in the neurologic recovery rate between the two groups. But in group A, the cervical range was maintained effectively than that of group B （P〈0.05）. Meanwhile there was significantly difference in axial symptom （P〈0.05）. Conclusion Patients treated with open-door laminoplasty, wearing a cervical collar can gain a good neurologic recovery rate, maintain the cervical rangeeffectively and reduce axial symptom obviously.
