The assessment of fractures is a key issue in forensic anthropology; however, very few studies deal with the features of fractures due to explosion in comparison with other traumatic injuries. This study focuses on fractures resulting from blast trauma and two types of blunt force trauma (manual compression and running over), applied to corpses of pigs; 163 osteons were examined within forty fractures by the transmission light microscopy. Blast lesions showed a higher percentage of fracture lines through the Haversian canal, whereas in other types of trauma, the fractures went across the inner lamellae. Significant differences between samples hit by blast energy and those runover or manually compressed were observed (p<0.05). The frequency of pattern A is significantly higher in exploded bones than in runover and compressed. Microscopic analysis of the fracture line may provide information about the type of trauma, especially for what concerns blast trauma.

The aim of the study was to analyze the structure and course of osteons in the compact bone of individual regions of the upper end of the femur and to consider the possible association with the course of typical peritrochanteric fracture lines. The issue of the architecture of this region has been dealt with by a number of authors since the first half of the nineteenth century, but until the present structural analysis it has been examined only by a few authors. We analyzed the structure of bones on specimens prepared by the method of repeated grinding, impregnating and polishing of the bone surface. We grounded and subsequently evaluated the bone in 20 dry specimens of the proximal femur, where the courses of the central vascular canals were described in the region of the femoral neck, the lesser trochanter, the greater trochanter, the intertrochanteric crest and line. The osteons were incorporated into a biomechanical model of the proximal femur and compared with the FEM model and correlation with the distribution of surface stresses was described. Certain areas were identified in the region of the trochanters where the course of osteons coincided with the course of the typical fracture lines of peritrochanteric fractures with typical fragments.
