We report the autopsy of a traffic accident victim with a rare atlas fracture. The deceased was 52-year-old man found dead on the road because of a traffic accident. We performed a postmortem computed tomography and an autopsy on the body. The sagittal reformation image of postmortem computed tomography showed a vertically separated anterior arch of atlas, suggesting a "horizontal fracture." Therefore, we assumed that cervical hyperextension may have been one of the forces that affected him during the accident. Minor spinal cord injury was also noted. In this case, postmortem computed tomography played an important role in detecting the spinal cord injury, considering the mechanism of the traffic accident, and supported the autopsy.

In large animal models of bone fracture repair, postmortem torsional testing is commonly used to assess healing biomechanics. Bending and axial tests are physiologically relevant, but much less commonly performed. Virtual torsional testing using image-based finite element models has been validated to postmortem bench tests, but its predictive value for capturing whole-bone mechanics and fracture healing quality under other physiologically relevant loading modes has not yet been established.

However, most existing genetic studies have been based on short-read sequencing methods, which capture fewer than half of the SVs present in any one individual. Long-read sequencing (LRS) enhances our ability to detect disease-associated and functionally relevant structural variants (SVs); however, its application in large-scale genomic studies has been limited by challenges in sample preparation and high costs.

The state-of-the-art approach to open reduction and fixation (ORIF) of zygoma fracture fragments is based on manual skills. Achieving high accuracy can be challenging. Our feasibility study on deceased body donors with artificial zygomatic fractures investigated whether virtual repositioning of the fractures and the use of customised 3D-printed titanium osteosynthesis plates was similar in accuracy to the conventional manual procedure, and whether the method was applicable in a clinical setting.

The position of the mental foramen is reported to change with age. This study aimed to examine age-related changes in the position of the mental foramen in men and women. Among 200 cases (age 21-100 years; 400 foramina) that underwent postmortem computed tomography, 109 (age 21-93 years; 218 foramina) with mandibular first and second premolars were examined using image analysis software to classify the position of the mental foramen according to Fishel's classification, and the χ² test was performed.
