A NON-INVASIVE PRE-TEST METHOD FOR DETERMINING HUMAN CADAVER SKELETAL QUALITY WITHOUT AFFECTING A CADAVER'S USABILITY IN AN EXPERIMENTAL PROGRAM IS PRESENTED IN CONJUNCTION WITH THE STANDARD POST-TEST "RIB BENDING" SKELETAL ANALYSIS. OSTEOPOROSIS (POROUS BONE) IS DETECTABLE, IN VARYING DEGREES, TO A TRAINED ORTHOPEDIST OR RADIOLOGIST IN THE LUMBAR SPINE OR PELVIS GIRDLE REGION OF A GIVEN SUBJECT. SUCH EXPERTISE IS NOT ALWAYS AVAILABLE TO THE RESEARCHER AT THE TIME CADAVER SELECTION MUST BE MADE. THUS, A RAPID AND ACCURATE ENGINEERING ANALYSIS OF SKELETAL QUALITY HAS BEEN DEVELOPED WHEREIN THE TECHNIQUE FOR DETERMINING THE PERCENT CORTICAL AREA (PCA) OF A LONG BONE (THE SECOND METACARPAL), DELINEATED ACCORDING TO AGE AND SEX, IS EXTRAPOLATED TO DETERMINE THE PCA USING A PRE-SELECTION RADIOGRAPH OF THE MID SHAFT VIEW OF A COMMONLY X-RAYED LONG BONE (FEMUR). THESE FEMUR PCA'S ARE PRESENTED AND DISCUSSED FOR APPROXIMATELY TWENTY CADAVERIC SUBJECTS UTILIZED IN BOTH CAR CRASH AND PEDESTRIAN IMPACT TESTS. A FURTHER PRE-TEST SKELETAL QUALITY DETERMINATION TECHNIQUE IN WHICH A SECTION OF AN EASILY EXCISABLE LONG BONE IS REMOVED (MID-SHAFT RADIUS) AND THE PCA ACCURATELY MEASURED IS PRESENTED FOR COMPARISON OF RESULTS.
