[The comparative characteristics of sawcuts across the femoral bone].

The objective of the present work was to study the differences between the morphological features of the wounds in the long tubular bones inflicted by joinery hand saws designed for longitudinal and transverse, sawing. The experimental injuries to the femoral bones were inflicted by the recurring and reciprocating saw movements. The hand saws had 5 mm high "sharp" and "blunt"-tipped teeth. A total of 40 experiments were carried out. It was shown that the sawcuts across the femoral bones and their edges have different size, shape, and morphological characteristics (defects, ledges, projections, bright spots) depending on the type of the saw, the sharpness of its teeth, and the mode of sawing. The results of the study may be used to improve diagnostics of injuries to the long tubular bones inflicted by different types of joinery saws.
