摘要

目的:评价齿状突参数在屈伸运动中的稳定性,验证不同颈椎体位下生理颈椎前凸预测公式的准确性。方法:收集中性位、屈曲位和伸展位标准颈椎侧位片,测量齿状突发生率(OI)、齿状突倾斜(OT)、C2斜率(C2S)、CL、T1斜率(T1S)和T1S-CL (T1S-CL)。Friedman’s检验用于评估三种颈椎位置之间参数的差异。采用Pearson相关系数(r)、决定系数(r²)、均方误差(MSE)和平均绝对误差(MAE)对公式CL = 0.36× OI - 0.67 × OT - 0.69 × T1S的预测性能进行评估和验证。结果:三种不同颈椎体位的成骨不全和T1S无显著差异(p = 0.162和p = 0.186)。三个颈椎体位(中性、屈曲和伸展)的生理CL预测值与实际值之间存在明显的正相关。结论:成骨不全是一个稳定可靠的解剖参数,不受颈椎屈伸运动的影响。OI可作为评价颈椎矢状平衡和代偿能力的补充参数。公式CL = 0.36×OI - 0.67×OT - 0.69×T1S提供了中性位生理CL的最佳预测。

The effect of cervical spine flexion-extension motion on odontoid parameters.

Objective: To assess the stability of odontoid parameters on flexion-extension motion and to validate the accuracy of the physiological cervical lordosis (CL) predictive formula across different cervical positions.

Methods: Standard cervical spine lateral radiographs in neutral, flexion, and extension positions were collected to measure odontoid incidence (OI), odontoid tilt (OT), C2 slope (C2S), CL, T1 slope (T1S), and T1S minus CL (T1S-CL). Friedman's test was used to assess the differences in parameters among the three cervical spine positions. The predictive performance of the formula CL = 0.36× OI - 0.67 × OT - 0.69 × T1S was assessed and validated using the Pearson correlation coefficient (r), coefficient of determination (R²), mean squared error (MSE), and mean absolute error (MAE).

Results: No significant differences were found for OI and T1S among the three different cervical spine positions (p = 0.162 and p = 0.186, respectively). There was a strong, significant positive correlation between the predicted value and actual value of physiological CL at three cervical positions (neutral, flexion, and extension). The predictions for the neutral position were the most accurate, with statistical measures of r = 0.85 (p < 0.01), R²=0.82, MAE = 4.28, and MSE = 27.77.

Conclusion: OI is a stable and reliable anatomic parameter, not affected by cervical spine flexion-extension motion. OI can serve as a supplementary parameter for evaluating cervical sagittal balance and compensatory ability. The formula CL = 0.36×OI - 0.67×OT - 0.69×T1S provides the best predictions for physiological CL in the neutral position.

期刊介绍: Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues. Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications. JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
