is a very easily missed fracture,because it is not very obvious on x ray
. It requires very careful scrutiny.So,that's why the orthopedic surgeon in your case picked up something, that was missed by the radiologist
.There is a very high chance that the orthopeadic surgeon was right in your case, and hence its advisable for you to follow his orders.
