Abstract:
In forensic anthropology, the differential diagnosis between peri- and postmortem bone fractures is mainly based on macroscopic criteria. In contrast, studies focusing on bone histology are very scarce. In a recent publication, we showed that (perimortem) fractures in fresh human bones exhibit a different osteonal microcracking pattern than (postmortem) damage in dry bones. In the current work, we explored whether this osteonal microcracking pattern is distinctive of the vitality of (perimortem) fresh bone fractures. To this end, we compared the number, length and structural distribution of microcracks in vital humeral fractures from forensic autopsy cases with experimentally reproduced, three point-bending fractures in fresh and dry human humeri. Half of the fresh experimental bones were fractured whilst applying axial compression, i.e., attempting to simulate intra vitam conditions more accurately. The results showed a similar osteonal microcracking pattern between vital fractures and experimental fractures of fresh humeri subjected to axial compression. Interestingly, this pattern was significantly different from the one observed in the experimental fractures of fresh humeri without axial compression and dry humeri. This supports our hypothesis that the osteonal microcracking pattern can potentially be used as a marker for vital perimortem trauma, providing a histomorphometric tool for fracture timing.

Abstract:
The increasing importance of trauma analysis by means of postmortem computed tomography (PMCT) is insufficiently reflected in forensic curricula, nor are best practice manuals available. We attempt to detect sharp force bone lesions on PMCT of closed forensic cases with the aims of assessing errors and pointing out patterns in anatomical location and manner of death (MOD). We investigated 41 closed sharp force fatality cases, with available PMCT and forensic reports. Two observers with different radiological training assessed the lesions on PMCT scans (2D and 3D) for comparison with the reports. Between 3% (suicides) and 15.3% (homicides) of sharp force injuries caused visible bone lesions. While our observations were repeatable, each forensic investigation left a similar number of bone lesions undetected. Injury patterns differed between MOD, with thoracic bone lesions being most frequent overall. Soft tissue injury location varied between the MOD. Associations between MOD and age as well as number of injuries were significant. The detection of bone lesions on PMCT for untrained forensic specialists is challenging, curricula and pertinent manuals are desirable. With the low frequency of bone lesions compared to soft tissue injuries, we should be aware when analyzing decomposed bodies.

Abstract:
The present study reports on the cultural marks encountered in three (possibly four) skeletons retrieved from primary deposits of the Maya Classic period at Palenque, Calakmul, and Becán, Mexico. We propose that the patterns of cut and stab lesions encountered in the trunks of these individuals stem from perimortem violence that accompanied heart removal from below the rib cage rather than from postmortem evisceration. We confirm the feasibility of this procedure by experimental replication in modern corpses. The interpretation of those procedures synthesizes information obtained from osteological, archaeological, and iconographic sources and leads to a broader discussion concerning the techniques, impact, and meanings of human heart sacrifice and associated body manipulations in Classic period Maya society. Methodologically, we conclude that direct skeletal evidence of heart sacrifice can be rare, imposing a cautionary caveat on the current discussion of mortuary remains in the Maya area.

Abstract:
A 9 years and 5 months old, neutered male, Rottweiler was presented for referral at the Small Animal Teaching Hospital, University of Liverpool, for investigations following a fracture of the left femur, which had occurred after minor trauma. Radiographs at the primary veterinary practice revealed a closed, slightly displaced, comminuted, proximal diaphyseal fracture, which had cortical thinning around the fracture site, suggestive of a pathological fracture. Advanced imaging (computed tomography) revealed polyostotic osteolytic lesions which contained contrast enhancing, soft tissue attenuating tissue, associated with cortical destruction throughout the appendicular and axial skeleton. Ultrasound-guided fine needle aspirates of four lesions (right scapular, right femoral, left pelvic and vertebral lesions) were assessed by a boarded clinical pathologist, confirmed diagnosis of a polyostotic osteosarcoma. The patient was euthanased and postmortem examination confirmed the diagnosis.

Abstract:
Clivus fractures are rare and severe entities, usually associated with vascular or cranial nerve lesions and frequently diagnosed postmortem. Cervical epidural haematomas can be traumatic or spontaneous, manifested in acute or chronic form, and are treated surgically in the majority of cases, although the conservative treatment also can be indicated to patients with incomplete and non-progressive deficits. The authors report the case of a female patient, 8 years old, victim of trampling in public way by a high velocity motorized vehicle, admitted in Glasgow 7, anisocoric pupils (left pupil midriatic), whose radiological investigation showed a transverse fracture of the clivus, cervical epidural haematoma and diffuse axonal injury. The patient was submitted to intracranial pressure monitorization, sedation and conservative treatment with dexamethasone, with good outcome. The authors also present a literature review.

Abstract:
In Forensic Anthropology, trauma analysis is essential for a correct understanding of the cause and the modality of death as well as for the interpretation of previous traumatic events which occurred in life. Both have important implications in criminal and humanitarian scenarios: to demonstrate whether a crime was committed, and to ascertain torture and maltreatment. Nevertheless, the assessment of a traumatic event, whether antemortem, perimortem or potmortem, is extremely challenging and often limited and altered by multiple variables, namely taphonomy. Few are the validated scientific methods which can help anthropologists in the interpretation of skeletal trauma, and which are often limited by the lack of known skeletal material on which to conduct research in order to acquire data, to validate methods and to study and create theoretical trauma and taphonomy models. Among the many known documented skeletal collections already presented officially to the international scientific community very few are equipped also with known/control data on trauma, and cause and modality of death. The Milan cemeterial Skeletal Collection, which is only part of the more consistent Milan Osteological Skeletal Collection housed at LABANOF (University of Milan) is one of the latter, and its presence has offered the chance to conduct research on the difficult field of trauma and taphonomy included in the Ph.D project. The first ever anthropological study of the skeletal sample of the Milan skeletal collection here presented, has been the starting point which permitted us to highlight the numerous diagnostic difficulties concerning trauma analysis and has provided the material on which to conduct the applied research for analysing the state of the art currently used by the discipline. As a consequence of the many limits arising from the first two research lines (on the diagnosis of antemortem lesions as well as the identification of perimortem injury), which appeared not satisfactory enough for a correct interpretation of skeletal lesions, the research has focused on the novel field of blood taphonomy in order to provide knowledge for the use of cell components and biomarkers as indicators of vitality and survival on skeletal trauma which represents more reliable future possible alternative solutions.
