Abstract

Study design: Observational study.

Objective: To analyze the cervical sagittal parameters for standing Digital radiography (DR) and supine Magnetic resonance imaging (MRI), and to further clarify the relationship between odontoid incidence (OI) and cervical spondylotic myelopathy (CSM).

Methods: 52 CSM patients aged 54.46 ± 2.89 years underwent both standing DR and supine MRI scans of cervical spine between November 2021 and November 2022. OI, odontoid tilt (OT), C2 slope (C2S), T1 slope (T1S), C0-2 angle, C2-7 angle (cervical lordosis [CL]), and T1S-CL were measured in both DR and MRI images using Surgimap (Version 2.3.2.1). Pearson correlation and linear regression were used to compare these parameters between the two modalities.

Results: Cervical sagittal parameters, including OI, OT, C2S, C0-2 angle, T1S, C2-7 angle (CL) and T1S-CL, showed no significant differences in the measurements between the two modalities. Based on the DR images, OI was related to OT (r = .386, P < .01), C2S (r = .505, P < .01), CL (r = -.412, P < .01), and T1S-CL (r = .320, P < .05), and OI was matched with CL (r2 = .170) and T1S-CL (r2 = .102). Based on MRI images, OI was related to OT (r = .433, P < .01), C2S (r = .516, P < .01), CL (r = -.355, P < .01), and T1S-CL (r = .271, P < .05), and OI matched with C2-7 (r2 = .126) and T1S-CL (r2 = .073).

Conclusion: OI is an independent parameter related to cervical anatomy and its measurement is unaffected by external factors. In patients with CSM, odontoid parameters may effectively describe the sagittal alignment of the cervical spine on DR and MRI images.

颈椎病患者中骨突发生率的重要性

研究设计观察性研究：方法：在 2021 年 11 月至 2022 年 11 月期间，52 名年龄为（54.46 ± 2.89）岁的 CSM 患者接受了颈椎立位数字X线摄影（DR）和仰卧位磁共振成像（MRI）扫描。使用 Surgimap（2.3.2.1 版）测量了 DR 和 MRI 图像中的 OI、ontoid tilt (OT)、C2 slope (C2S)、T1 slope (T1S)、C0-2 角、C2-7 角（颈椎前凸 [CL]）和 T1S-CL。使用皮尔逊相关和线性回归对两种模式的这些参数进行比较：颈椎矢状面参数，包括 OI、OT、C2S、C0-2 角、T1S、C2-7 角（CL）和 T1S-CL，在两种模式下的测量结果无显著差异。根据 DR 图像，OI 与 OT（r = .386，P < .01）、C2S（r = .505，P < .01）、CL（r = -.412，P < .01）和 T1S-CL （r = .320，P < .05）相关，OI 与 CL（r2 = .170 ）和 T1S-CL （r2 = .102）匹配。根据 MRI 图像，OI 与 OT（r = .433，P < .01）、C2S（r = .516，P < .01）、CL（r = -.355，P < .01）和 T1S-CL （r = .271，P < .05）相关，OI 与 C2-7 （r2 = .126）和 T1S-CL （r2 = .073）匹配：结论：OI是一个与颈椎解剖相关的独立参数，其测量不受外部因素影响。在 CSM 患者中，蝶骨参数可有效描述 DR 和 MRI 图像上颈椎的矢状排列。
