在检查保存不佳的身体时，估计死亡时间尤其困难，这取决于检查人员的经验，以及与以前记录的显示出类似特征的病例的比较。本研究报告了过去十年通过西班牙马德里Anatómico Forense研究所的Antropología y Odontología Forense实验室(LAF)的工作获得的信息，特别是评估了骨折类型对尸检的影响。从1992年至2002年法医论坛最初审查的225起法医案件中，从西班牙大陆不同地区挑选了29起案件样本。建立了一项数据收集方案，以反映现有专门文献中所分析的样本中存在的死亡时间与死后变化程度之间的关系，在所审查的环境中，这些关系被分为以下阶段：阶段1(腐烂)：一周至一个月在表面，两个月在水中。第二阶段(初始骨架化)：在水面上两个月，在水中五到六个月。第三阶段(高级骨架岩化)：地表六个月至一年半，埋藏两年半。第四阶段(完全骨化)：在地表大约一年，埋藏三年。本文还提供了腐肉昆虫活动、位置、气候、季节性和捕食者的影响的有用信息。
Estimating time since death is especially difficult in the examination of poorly preserved cadavers and depends on the experience of the examiner and comparison with previously documented cases showing similar characteristics. The present study reports on information obtained over the past ten years through the work of the Laboratorio de Antropología y Odontología Forense (LAF) of the Instituto Anatómico Forense de Madrid, Spain, in particular evaluating how the type of fracture influences postmortem change. From the original 225 forensic cases examined between 1992 and 2002 in the LAF, a sample of 29 cases were selected from various regions of the Spanish mainland. A data collection protocol was established to reflect factors which the existing specialized literature, documenting the relation existing in the sample analyzed between time since death and the extent of postmortem change, which in the environments examined are distributed into the following phases: Phase 1 (putrefaction): one week to one month on the surface and two months in water. Phase 2 (initial skeletonization): two months on the surface and five to six months in water. Phase 3 (advanced skeltonization): six months to 1.5 years on the surface and 2.5 years buried. Phase 4 (complete skeletonization): about one year on the surface and three years buried. This paper also provide useful information on the impact of carrion insect activity, location, climate, seasonality, and predator.
