Abstract

Rabbit femora were fractured with different strain rates (static and dynamic) with measurement of the bone marrow pressure. In comparison with previous research, this investigation measured bone marrow pressure during the actual moment of fracturing. The results showed that the amount of fat emboli is dependent on the strain rate, and occurs mainly at the moment of fracture, when elastic strain energy is released in the form of pulse waves. A further group of rabbit femora were subjected to standarised pulse waves on the bone marrow. The number of fat emboli produced is proportional to the strength and number of these waves.
