HydroxyBMD Physicians in hospitals and private practice published more reports in the New England Journal as well as individual reports. All have reported unusual transverse femur fractures with a break projection of cortical bone with irregular bone thickening HydroxyBMD along the femoral shaft as seen through X-ray film. This type of break is rare but would normally be seen in a car accident victim or someone who had fallen down a flight of stairs where you would have some great horizontal force pushing on the femur. Keep in mind that the strongest bone in the body is the femur and requires great force to break. http://t-rexmuscleadvice.com/hydroxybmd/
