i don't know what country that you are currently living but you may want to try and get a second opinion from another orthopedic surgeon. since i have no way of personally evaluating your son reviewing those x-rays knowing the exact location on the femur etc. so i really cannot offer any patient-specific opinion. pediatric femur fractures can be very challenging to properly treat especially in a two year old so continue to be your son's advocate and insist that another orthopedist take a look at him.
my 2 year old son broke his femur while playing 2 weeks ago and doctors treatment seems ineffective. doctors says he has a spiralled dislocated fracture and told us that they would do skin traction method to align the broken bones. . however my son is unable to keep still and the bones do not seem to be in line in the x-rays. . it has been exactly 2 weeks today and there has been no progress. i am extremely worried and do not know if his leg is going to be ok or not. . i understand from my web research that spica casting should have been done but doctors told me they dont do it in my country.
