测量方法:

手术时间以手术开始切皮至手术缝合结束时间为准; 术中透视次数按次记录; 导针置入次数包括置入及调整次数; 术后疼痛数字评分,根据NRS评分法,记录患者术前及术后不同时间段的疼痛评分; 神经血管损伤、脑脊液漏及切口感染,属于术后并发症,根据术后观察并分组记录; 骨折复位及愈合,根据影像学复查,判断骨折的复位满意度及愈合时间,作分组记录; 末次颈椎残障功能指数,根据NDI标准评估末次颈椎功能指数,分数

Measure time point of outcome:

From before the operation to one year after the operation

Measure method:

Record and print the angles and depths of the preoperative designed screw channels in the group (taking the midpoint of the lower edge of the lower endplate of the C2 vertebral body as the needle insertion point, the needle insertion Angle was measured as the Angle between the line connecting the guide needle and the anterior edge of the C2 vertebral body, and the depth was measured as the depth at which the guide needle was inserted into the C2 vertebral body), and compare them with the postope

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

主要包括两部分,病例资料及术后随访数据。记录打印组术前设计螺钉钉道的角度与深度,并与术后影像学测量数据比较;记录两组患者的手术时间、术中透视次数、导针预置调整次数、术中出血量、骨折愈合率;记录两组患者手术前及术后3个月及末次随访的VAS评分、JOA评分、CROM评分及ASIA评分。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

It mainly includes two parts: case data and postoperative follow-up data. Record the Angle and depth of the screw channel designed by the printing group before the operation and compare them with the postoperative imaging measurement data; Record the operation time, the number of intraoperative fluoroscopy, the number of preset adjustments of the guide needle, the intraoperative blood loss and the fracture healing rate of the two groups of patients; The VAS score, JOA score, CROM score and ASIA score of the two groups of patients before the operation, 3 months after the operation and at the last follow-up were recorded.
