|Description||The paper represents an experimental study of the behaviour of metal residues on bone following blunt force injury. Ten fresh sub-adult bovine metatarsal bones were manually cleaned of soft tissues. They were then struck by metal bars on the external surface of the mid-diaphysis. All blunt metal instruments used in this study left a sign in the form of single particles, a smear or a powder-like deposit on the bone surface. The residues of all three metal implements were detected on the bone surface, 0.3-10 mm from the fracture border. The presence of metal particles was confirmed in all samples struck with iron and copper and in two of six aluminium samples; no particles were detected on the negative control. Chemical composition of residues highly corresponded with the composition of applied bars.|
