Anthropologists evaluate injuries in skeletal remains by examining their macroscopic and microscopic features, utilizing empirical and theoretical knowledge about trauma formation and healing. Finite element analysis (FEA), which enables computational simulation of the structural stress on bone tissue and skeletal components based on their shape and defined physical properties, could be used to supplement such assessments. This study evaluates FEA's applicability for simulating injuries observed in historical skeletal materials by confronting the method with a lower limb trauma observed in nearly 300-year-old mummified remains. The simulations were computed using algorithms integrated into the Mechanical Finder software. Postmortem computed tomography (CT) data were acquired using a Phillips Brilliance CT 64 scanner with a slice thickness of 0.3 mm and a 1024 x 1024 matrix. The dynamic simulations focused on exploring the relationship between the direction and speed of the projectile and the formation and propagation of skeletal trauma. FEA provided insight into the mechanical limits of the affected bones across varying projectile velocities and impact directions. The observed fractures most closely matched the results of the simulation where the projectile struck from the lateral side. The obtained information supplemented the osteological diagnosis based on the visual assessment of the trauma. However, the informational value of the results was reduced because the software did not show the spread of finer fractures and was unable to simulate covering soft tissues. On a general level, Mechanical Finder facilitates the simulation of bone biomechanics primarily through its ability to create nonhomogeneous FEA models directly from CT scans. Nevertheless, its usage remains challenging for experts without a biomechanical background.
