I know someone who broke their arm early January, was plastered for 6 weeks. Cast was then removed late February and they were told your arm is still broken. Not going to put another cast on as you will lose too much mobility. Early April they were in Liverpool for a hospital appointment for something else, consultant noticed that they were holding arm. Asked what was up, they explained what had happened. They were sent straight away for a scan and orthopedic consultant summoned. The orthopedic consultant said this should have been operated on straight away. Where the break was it would never have healed. He also said whoever left your arm like this should be struck off. Early May the arm had major reconstruction in Liverpool.
