After a failure intramedullary nail surgery, I had an ilizarov surgery after cutting out about 3cm of femur and lengthening those 3cm again in one surgery. but this surgery also failed with the old fracture but not the lengthening. so I had another try with ilizarov but with a bone grafting after cutting of about 7cm from the femur with no lengthening and it worked. my question is "what is my options to get those 7cm back since the femur has 26 holes in place of each nail of ilizarov?"
