Australian boy comes to West Palm Beach for surgery to save his leg

A mother’s instinct to protect her son brought them from Australia to West Palm Beach for surgery that would change his life. William Dickinson is 3 1/2-years-old and has been in some type of leg cast almost his whole life. When he was a baby, William was diagnosed with a rare disease called CPT, or congenital pseudarthrosis. It means his broken leg bone won't heal.
