Massachusetts man will travel to China for cutting-edge surgery

Quincy, MA, resident David Maynard is preparing to go to China to undergo cutting-edge surgery not available in the United States because it is regarded as risky. Maynard believes the treatment is a step toward treating chronic ailments that began in 1999 with a herniated disc in his upper back. The Chinese doctors will inject stem cells from an umbilical cord into Maynard's spine.
