About Maria’s Marvelous Bones

While playing with her little brother on the couch, Maria falls and breaks her arm. Her father rushes her to the hospital, where Maria meets the nurses, doctors, X-ray technician, orthopaedic surgeon and cast technician who are responsible for healing her fractured arm. Maria learns all about how her body works and how bones heal — plus a little bit about being brave. Written by Dr. Carrie Kollias, an orthopaedic surgeon who specializes in the treatment of children, Maria’s Marvelous Bones educates young readers about bones as well as about the diverse members of the healthcare team who work together to help heal injury.
