Human: Forensics and Pathology

This comparative pair of left femurs illustrates that the condition created by osteoporosis is not detectable by merely looking at the outside of the bone; instead, a bone density test would reveal the loss of bone mass. The osteoporotic bone seems identical to the healthy femur until one picks it up and compares its weight (147 grams) to that of the healthy femur (261 grams). We took these weights from the measurements of the natural bones of which we made casts. Contains KO-170 and SC-211-F.
