💡LON vs Fitbone vs Precice 2 - Which limb lengthening method suits you the best?
▶️ In this video, we compare the three advanced limb lengthening techniques: LON (Lengthening Over Nail), Fitbone, and Precice 2.
1️⃣ The LON method is the most cost-effective option. It combines an internal nail with an external fixator and allows weight-bearing from the first week after surgery. Patients can usually gain up to 10 cm in the femur or 7 cm in the tibia, but it requires pin site care and leaves more visible scars.
2️⃣ The Fitbone system, developed in Germany, is a fully internal motorized nail made of stainless steel. It is controlled by a small transmitter and lets patients stand and walk with support soon after surgery. Fitbone offers comfort, minimal scarring, and no risk of pin-site infections, with height gains of 7–8 cm. The main limitation is its higher cost compared to LON.
3️⃣ The Precice 2 method, created in the United States, uses a titanium nail that lengthens with an external remote controller. It leaves very small scars and offers precise, controlled lengthening, but because weight bearing is limited, patients often need a wheelchair during the lengthening phase. It allows similar height gains of up to 8 cm in the femur or 7 cm in the tibia.
Each method has advantages and trade-offs, from affordability and faster mobility with LON, to comfort and cosmetic benefits with Fitbone, to high precision and small scars with Precice 2.
