Forensic histology & bone

• Species differentiation

– Primate/non-primate

– Human/other primate

• Age estimation

– Osteon counting

• Post mortem interval

• Bony response to injury

Histology & Injury response

• Histological signs of bony response to injury –especially in children

• Cattaneo et al ‘The Detection of Microscopic Markers of Hemorrhaging and Wound Age on Dry Bone: a Pilot Study’ AJFMP 2010 31(1):22-26

• “A total of 6 samples of fractured bone (cranium, rib, and tibia) were taken from cadavers with known time of survival between trauma and death. Time intervals ranged from a few seconds after the bone fracture had been inflicted, to several hours, days, and weeks. A negative control was included (postmortem fracture)”
