Hello. I have one side shotening. Hase somone experinece in doing e.g. left femur and left humerus simoultanoulsy ?
I think it's possible to do one side (femur+humerus) simultaneously because you still have the other side for support and to manage around, but you can't do both femurs(or tibia) and both humerus simultaneously. That's nearly impossible because you'll be a vegetable for a very long time.
If you have hemiatrophy the best thing to do is talk to an orthopedic doctor about what it is to be done. The good news is that you don't necessarily need one of the doctors on this site. You can find plenty of very good orthopedic surgeons that can help you at more reasonable prices or even covered by insurance.
