舌骨是骨骼中一种独特的骨骼，不与任何其他骨骼连接。附于舌骨的舌骨肌可能在颈部力学中起作用，但对其功能的分析需要量化舌骨力学。本研究的目的是通过5种姿势的X线片获得舌骨在大范围屈伸运动中的详细运动学。舌骨在矢状面上的位置与头部、下颌和椎骨运动有关。舌骨运动学的性别差异也进行了研究。我们假设：（1）舌骨在矢状面的位置与头部、颌骨和椎骨的运动呈线性相关;（2）舌骨的位置、大小和运动学具有性别特异性。我们发现，舌骨的X，Y，和角的位置一般有很强的线性相关性的位置，头部，颌骨，颈椎C1-C4。舌骨X和角位置也与C5相关。在舌骨C1-C5的某些回归中发现了性别差异。舌骨的角度和线性测量显示绝对值的性别差异，这是不明显的姿势或颈部大小标准化后。将这些结果应用于颈部模型将能够准确地建模舌骨肌。这可能对分析颈椎力学，包括颈部结构和植入物上的载荷有影响。
The hyoid bone is a unique bone in the skeleton not articulated to any other bone. The hyoid muscles, which attach to the hyoid bone, may play a role in neck mechanics, but analysis of their function requires quantifying hyoid bone mechanics. The goal of this study was to obtain the detailed kinematics of the hyoid bone over a large range of flexion-extension motion using radiographs at 5 postures. The position of the hyoid bone in the sagittal plane was characterized with respect to head, jaw, and vertebral movements. Sex differences in hyoid kinematics were also investigated. We hypothesized that (1) the position of the hyoid bone in the sagittal plane is linearly correlated with motion of the head, jaw, and vertebrae, and (2) the hyoid position, size, and kinematics are sex-specific. We found that the hyoid bone X, Y, and angular position generally had strong linear correlations with the positions of the head, jaw, and the cervical vertebrae C1–C4. Hyoid X and angular position was also correlated to C5. Sex differences were found in some regressions of the hyoid bone with respect to C1–C5. The angular and linear measurements of the hyoid bone showed sex differences in absolute values, which were not evident after normalization by posture or neck size. Incorporating these results to neck models would enable accurate modeling of the hyoid muscles. This may have implications for analyzing the mechanics of the cervical spine, including loads on neck structures and implants.
