Interpretations of gunshot wounds
Fracture assessment triad
Fracture features
circular defect with internal beveling, circular/irregular defect with beveling, keyhole defects, radiating fractures, gutter defects, concentric defects, bone plug, foreign materials debris and residue
features and characteristics that could be used for gunshot interpretations
Intrinsic factors
Viscoelasticity, anisotropicity, buttresses, sutures, foramina, age, skeletal health, micromorphology
Features of the bone that interact with and direct how the bone fractures
extrinsic factors
velocity, mass, bullet design, cavitation
outside factors related to the production of trauma
Interpretations
A combination of fracture features and intrinsic factors can help give clues about extrinsic factors interpretations
projectile vs blunt trauma, direction, handgun vs shotgun, caliber/gauge elimination, velocity range, sequencing, medicolegal shooting distance
Author argues that the fracture assessment triad would be largely useful in gunshot trauma interpretations
need more specificity in caliber estimations
triad should be explored for ammunition type estimations
need more research in firearm/target distance from osseus evidence
research needed for understanding micromorphology and anisotropic effects on fractures
more research needed for effects of previous trauma on projectile trauma
more research needed on understanding caliber and temporary cavitation
