"Pelvis broken and made to walk"

My 93 year old mother took a fall. After attending Gloucester Royal she had X-rays and wad told she had previously fractured her pelvis and the fall had irritated it. We informed the doctor that she had never fractured her pelvis before but he insisted she had and the nurses were trying to make her Walk to the toilet in grave pain (the nurses were only going by what they were instructed to do ). My mother was transferred to the Dilke Cinderford where she had more X-rays and it was found she had snapped her pelvis in 2places, Gloucester royal cannot say they never seen this on the X-ray and they were pushing my mother to walk. This issue will not stop here the matter is being taken further.
