As the velocity of an aircraft increases, the airforces increase as the square. Forces imposed on exposed surfaces of a human ejected into the airstream can cause injury to extremities, expecially if they are unconstrained. A summary of such injuries over a ten year period has been compiled by Combs. Although data exists on the stregth and stiffness of bone, there is an absence of information pertaining to whole, human, unembalmed cadaveric long bones. A device has been designed and constructed to apply torsion, bending or combined bending and torsion to whole human long bones. It is capable of applying controlled loadings to induce fracture in cadaveric specimens. The purpose of the experiments is to mimic the fractures that can occur during wind flail in ejection seat operations. A description of the newly designed apparatus is the main purpose of this paper. The apparatus is, in reality, a universal osteoclast which is capable of a wide variety of experiments.
