Quote5. Combined tibia (4 cm) and femur (4 cm) lengthening three weeks apart, followed by rebreaking of femur and tibia with the same PRECICE in place one year later with a second lengthening of 4 cm in each bone (up to 16 cm in height; cost $280,000 USD, PRECICE-Stryde)
It's offered by doctor Paley and it's possible 16cm at total. If you have money and time, do you think it's a good idea?
