often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up X-rays because their orthopedists are concerned about possibly having misjudged the stablilty of the fracture. When a number of follow-up X-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable
