Bone strength of the radius and ulna in the non-human primate.
The technique and measurement of the bone strength of the radius and ulna in the non-human primate are presented. The aim of this study was to find a relationship between the mechanical strength of an intact radius and ulna forearm and its collateral isolated radius and isolated ulna which would be of assistance in the studies on mechanical bone strength and bone healing. The findings include: (1) bone strength is significantly influenced by factors such as age, sex, and body weight; (2) wide variation in normal bone-tissue strength exists among similar individuals; (3) there are differences in bone strength in the same individual if contralateral sides are compared; (4) growing bones are very elastic and are able to bend to an angle of up to 90 degrees before a fracture occurs; (5) soft tissue structures (such as muscle, interosseous membrane, and tendons) do not contribute to the strength of a diaphysis in low velocity injuries; and (6) the midshaft area of the radius is approximately 10% stronger than that of the ulna in the adult.
