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 stability of the frac- ture. 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. Which of the following, if true, most strengthens the argument?

B

初始X光测试表明没有fracture, so the follow up is not needed

还是不太明白

不知不觉

好象有人选B,有人选C

前提是骨折了，不讨论没有骨折的情况。选c

俺也选C,那个措施重复使用，太浪费钱了

我本来选的B，现在觉得C是对的
因为C说在不同医院的很多医生都review过这个X光片了，就是大家都确认没问题了，有问题的几率已经很小了，可以断定不需要再做复诊了~
B说做了X-Ray的这些脚踝，通过X-ray一看根本就没问题，那不就说开始的诊断是错的了么，所以就还是需要复诊咯，而原文是说开始已经诊断对了无需花钱复诊了，所以B有削弱的倾向~
