FAT EMBOLISM AFTER STATIC AND DYNAMIC LOAD

Rabbit femurs were fractured with different strain rates (static and dynamic) and the bone marrow pressure measured. Unlike previous research, bone marrow pressure was measured at the actual moment of fracturing. The results show that the amount of fat emboli is dependent on the strain rate, and that embolism occurs mainly at the moment of fracture, when elastic strain energy is released in the form of pulse waves. Another group of rabbit femurs were subjected to standardized pulse waves on the bone marrow. The number of fat emboli produced was proportional to the wave strength and number.
