The Erratic Behavior of Lesions in Burnt Bone.

This study analyses depressed fractures (by blunt force trauma) and circular full-thickness injuries (drill injuries and gunshot wounds) in charred bones. Fifty bovine ribs (total 104 lesions) were divided into three groups. The first group consisted in 20 depressed hammer-produced fractures; in the second one, 60 round drill-holes were produced (30 circular, 30 semicircular); in the third group, 12 fleshed and 12 skeletonized ribs were hit by 9-mm bullets.
