摘要

橄榄球运动中的致命颈椎损伤往往发生在对抗过程中。导致这些损伤的根本机制仍不清楚,在损伤预防文献中,颈部过度屈曲和屈曲都被认为是致伤因素。本研究的目的是评估头部先着地的橄榄球擒抱动作中,撞击前的头颈姿势对颈部椎间负荷和运动的影响。通过使用经过验证的、针对特定对象的橄榄球运动员肌肉骨骼模型,以及由体内和体外数据驱动的计算机模拟,我们研究了颈椎在这种撞击条件下的动态响应。模拟结果表明,最初的头颈矢状面姿势会影响椎间负荷和运动学,颈部伸直会导致屈曲和超生理的椎间剪切和屈曲负荷和运动,这是典型的双侧椎面脱位损伤。相比之下,最初屈曲的颈部会增加轴向压缩力和屈曲角,但不会超过椎体间的生理极限。这些发现提供了客观证据,可为伤害预防策略或橄榄球法的修改提供参考,从而提高橄榄球比赛的安全性。

An Extended Neck Position is Likely to Produce Cervical Spine Injuries Through Buckling in Accidental Head-First Impacts During Rugby Tackling

Catastrophic cervical spine injuries in rugby often occur during tackling. The underlying mechanisms leading to these injuries remain unclear, with neck hyperflexion and buckling both proposed as the causative factor in the injury prevention literature. The aim of this study was to evaluate the effect of pre-impact head–neck posture on intervertebral neck loads and motions during a head-first rugby tackle. Using a validated, subject-specific musculoskeletal model of a rugby player, and computer simulations driven by in vivo and in vitro data, we examined the dynamic response of the cervical spine under such impact conditions. The simulations demonstrated that the initial head–neck sagittal-plane posture affected intervertebral loads and kinematics, with an extended neck resulting in buckling and supraphysiologic intervertebral shear and flexion loads and motions, typical of bilateral facet dislocation injuries. In contrast, an initially flexed neck increased axial compression forces and flexion angles without exceeding intervertebral physiological limits. These findings provide objective evidence that can inform injury prevention strategies or rugby law changes to improve the safety of the game of rugby.
