If your break your arm, you may find your doctor using sound help you. Doctors are excited about a new way they have found to heal broken bones. This new technigue uses sound waves which seem to make bones heal faster. The machine sends out sound waves toward the broken bone. The waves make the bone cells shake. This shaking causes the cells to give off chemicals that mend the bone. Using sound waves can take only six weeks insteand of 12 weeks for the bone to mend.
