The Girl Who Couldn't Move

A young student begins to suffer from paralyzing pain in his back. A couple adopts a girl and they find a huge and swollen lump on her shoulder. Initially suspected to be severe neurofibromatosis, the efforts of doctors to relieve the child's condition by conducting an amputation of the affected arm only makes things worse when bone begins overrunning the site of the amputation, revealing her condition to be the lethal and progressive disease fibrodysplasia ossificans progressiva.
