Sub-axial cervical spine(C spine) distraction flexion injuries, known as cervical sprains, have been divided into either "benign" or "severe" sprains depending on the integrity of the posterior longitudinal ligament (PLL) of the spinal column. It is a very uncommon injury and rarely reported in the literature. Most of the reports in the literature discuss this injury in the adult age group and so the adolescent age group was also considered to follow the same model of progression of mechanical instability depending on the degree and extent of structures injured, including the PLL as a cutoff factor between a "stable" and an "unstable" injury.
We report three cases of adolescents with severe cervical sprains at the C2-C3 level and argue the integrity of PLL as a determinant factor in the sagittal stability of the C spine in this age group.
下颈椎（C 脊柱）牵张屈曲损伤，即颈椎扭伤，根据脊柱后纵韧带（PLL）的完整性分为“良性”或“严重”扭伤。这是一种非常罕见的损伤，文献中鲜有报道。文献中的大多数报告讨论的是成人年龄组的这种损伤，因此青少年年龄组也被认为遵循相同的机械性不稳定进展模式，取决于受伤结构的程度和范围，包括将 PLL 作为“稳定”和“不稳定”损伤之间的分界因素。
我们报告了 3 例 C2 - C3 水平严重颈椎扭伤的青少年病例，并论证了 PLL 的完整性作为该年龄组 C 脊柱矢状面稳定性的决定因素。
