Document Summary

Trauma: physical disruption of living tissues by outside forces. Not all injuries are evident on the skeleton. Fractures: break in the continuity of bone and teeth. Can provide some info about the events surrounding death and even manner of de. Hematoma --> soft callus --> hard callus --> remodelling. Bones are flexible due to high collagen content: Sometimes a mixture of ante-, peri-, and post-mortem fractures. The study of how bone breaks when force is applied. Amount (magnitude) and duration of stress > than the bone"s ability to resist strain --> fracture cture (young"s modulus) Different fracture forces can cause different fracture types. Incomplete: bone does not break all the way through. Normal in childhood, but may also suggest child abuse. Incomplete fractures in adults can be caused by stress and repetitive impacts (e. g. march. Shears toward the compression side, forming a wedge. Typical in vertebral bodies (esp. after bone loss)
