| 目的 应用影像归档和通信系统测量下颈椎椎管旁螺钉（paravertebral foramen screw, PVFS）相关参数并探讨其可行性。方法 按时间先后选取2016年12月至2017年12月因颈椎退变或外伤于我院行颈椎手术的病人100例，收集上传至PACS的颈椎三维CT数据，分别测量C3~C6侧块螺钉和椎管旁螺钉的钉道长度，并进行比较分析。结果 C3~C6椎管旁螺钉10°和15°误差范围内的安全钉道长度分别为（12.54±1.16） mm、（11.76±1.11） mm，而侧块螺钉的钉道长度和有效钉道长度分别为（14.58±1.20） mm、（12.83±1.21） mm。对于C3~C6椎体，椎管旁螺钉10°、15°误差范围内的钉道长度与侧块螺钉的钉道长度相比，差异均有统计学意义（P均＜0.05），但是与侧块螺钉的有效钉道长度是接近的。结论 下颈椎椎管旁螺钉安全固定长度可等同于侧块螺钉固定有效长度，且其方法安全合理，基于影像学角度探究而言，下颈椎椎管旁螺钉具有临床应用的可行性。 |

| Objective To explore the relevant parameters and clinical feasibility of paravertebral foramen screw (PVFS) in sub-axial cervical spine based on the picture archiving and communication system. Methods A total of 100 patients diagnosed with cervical spine trauma or cervical degeneration were enrolled in chronological order who underwent cervical spine surgery in our hospital from December 2016 to December 2017. The preoperative three-dimensional cervical CT images of all patients were obtained to upload to the PACS. The length of PVFS and lateral mass screw (LMS) were measured, respectively, and used for comparative analysis. Results The mean safe length and effective length of PVFS within the error range of 10° and 15° at C3-6 was (12.54±1.16) mm and (11.76±1.11) mm, respectively. The mean length of LMS and effective length of LMS at C3-6 was (14.58±1.20) mm and (12.83±1.21) mm, respectively. Comparison of the safe length of PVFS with the length of LMS showed statistically significant difference (P＜0.05). However, there was no significant difference in the effective length between the two groups. Conclusion The mean safe length of PVFS in the sub-axial cervical spine is approximate to effective length of LMS, besides it's safe and reasonable inserting technique. In terms of imaging study, PVFS used in sub-axial cervical spine is feasible in clinical application. |
