The cost of lengthening surgery for the femur typically ranges from $20,000 to $100,000, depending on various factors such as the surgical technique used and the facility. When considering both the femur and fibula, expenses could be higher. Performing surgeries in these areas simultaneously is possible, which may save time and reduce recovery periods. It's essential to consult with an experienced orthopedic surgeon to discuss your specific needs, underlying conditions, and the best approach to achieving your goals safely. They will provide tailored recommendations and support throughout your journey.
