Decapitation following suicidal hanging is rarely encountered in forensic practice. The authors report a case of suicidal hanging resulting in decapitation following a fall of 5m. This case is compared with 30 cases found in the literature. Several factors including type of rope, skin abrasion, level of the severed vertebrae, thyroid cartilage and hyoid bone injuries and vital signs are studied. The force applied to the neck and the kinetic energy were calculated. The kinetic energy (ranging from 1820 to 7310J) takes into account the weight of the victim but also the length of the rope (height of the fall). The speed of the body as it is stopped by the rope ranged between 6.49 and 14.01ms.
法医实践中很少遇到自杀性缢吊后身首分离的情况。作者报告了一例自杀性缢吊案例，该患者从5米高处坠落导致身首分离。本案例与文献中找到的30例案例进行了比较。研究了包括绳索类型、皮肤擦伤、椎体切断水平、甲状腺软骨和舌骨损伤以及生命体征等几个因素。计算了施加在颈部的力和动能。动能（范围为1820至7310焦耳）既考虑了受害者的体重，也考虑了绳索长度（坠落高度）。身体被绳索阻止时的速度在6.49至14.01米/秒之间。
