Hyoid is a U-shaped bone present in the ventral aspect of neck at the level of fourth cervical vertebra. It is a small bone placed between the root of tongue and the thyroid cartilage. Fracture of hyoid has great significance and importance in forensic pathology. It is well documented that fracture of hyoid is a recognized finding and indicator of strangulation (more common in manual or throttling than by ligature). Fracture of hyoid is less frequently reported in hanging. Discriminant function analysis was used with all predictors (width of hyoid, antero-posterior length of hyoid and length of greater cornu) were entered together. The analysis showed that 96.0% of original grouped cases could be correctly classified.
舌骨是一块呈U形的骨头，位于颈部腹侧第四颈椎水平。它是一块小骨头，位于舌根和甲状软骨之间。舌骨骨折在法医病理学中具有重大意义。有充分的文献记载，舌骨骨折是勒死的一个公认发现和指标（在手动扼杀或掐颈中比用绳索勒死更常见）。舌骨骨折在缢死中较少见。使用判别函数分析，将所有预测变量（舌骨宽度、舌骨前后长度和大角长度）一起输入。分析表明，96.0%的原始分组病例能够被正确分类。
