hi there i have just been told after seeing a orthopedic dr that my son has an half an inch shortage on his left leg(femur) .which is very noticeable too.
they measured his legs tibia and femur on both legs,took x-rays. he also has half an inch less in diametre too. he has to have built up shoe,to level him out and then wait to see again. hope this helps.
After breaking my femur,I went through a bunch of surgeries. My right leg ended up being shorter than my left. At first,it didn't bother me but then I started to get a lot of pain in my right heel and left hip. A trip to the orthotics/prosthetics office showed that my right leg was an inch shorter than my left. They built a shoe with the added inch and the pain went away within a day. Hope this helps.
