回顾性图表回顾。作者旨在调查临床和放射学参数在接受后路颈椎手术的患者中的作用，以及它们与 C5 麻痹严重程度和恢复时间的关系。术后 C5 麻痹影响接受后路颈椎手术的患者的 1%-30%减压，有或没有融合。这种并发症的原因和避免仍然存在广泛争议。对接受后颈椎手术的患者进行的单一机构审查的重点是使用与感兴趣的患者群体相关的特定通用程序技术代码。如果患者术前和术后影像学不充分，以及既往有颈椎手术史、并发前路手术、硬膜内病理、脊柱肿瘤或脊柱创伤史，则被排除。术前和术后图像的放射线测量通过随后的组内相关系数分析完成，以确认测量的精度。在 105 名患者中，35 名 (33%) 患者出现 C5 麻痹。其中 24 例 (69%) 的麻痹完全消失，平均恢复时间为 8 个月。术前人口统计和放射学参数表明，麻痹缓解和未缓解的患者之间存在异质性。术后 C2-C7 前凸变化增加的患者 (P = 0.011) 与恢复可能性降低相关。无吸烟史的患者（P = 0.009）从 C5 麻痹中恢复的可能性增加。退行性颈椎疾病治疗中前凸程度的增加对 C5 麻痹的恢复率起着重要作用。在术前计划确定所需的脊柱前凸量时应考虑这一点。此外，没有吸烟史的患者康复率较高。IV 级。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。

A retrospective chart review.The authors aim to investigate the role of clinical and radiographic parameters in patients who underwent posterior cervical surgery, and their association with C5 palsy severity and time to recovery.Postoperative C5 palsy affects 1%-30% of patients undergoing posterior decompression, with or without fusion. Causation and avoidance of this complication remain widely debated.A single institution review of patients who underwent posterior cervical spine surgery was focused on using specific Common Procedural Technology codes associated with the patient population of interest. Patients were excluded if they had inadequate pre and postoperative imaging, as well as a history of prior cervical spine surgery, concurrent anterior surgery, intradural pathology, spinal tumor, or spinal trauma. Radiographic measurements of the pre and postoperative images were completed with subsequent intraclass correlation coefficient analysis to confirm the precision of measurements.Out of 105 total patients, 35 (33%) patients developed a C5 palsy. Twenty-four (69%) of those palsies completely resolved, with a median time to recovery of 8 months. Preoperative demographics and radiographic parameters demonstrated heterogeneity among those patients who did and did not have a resolution of palsy. Patients with increased change in C2-C7 lordosis (P = 0.011) after surgery were associated with decreased likelihood of recovery. Patients without a smoking history (P = 0.009) had an increased likelihood of recovering from C5 palsy.The degree of increased lordosis in the treatment of degenerative cervical disease plays a role in the rate of recovery from C5 palsy. This should be considered during preoperative planning in determining the amount of lordosis desired. In addition, patients without a smoking history were associated with a higher rate of recovery.Level IV.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
