The FitboneTM Intramedullary Limb-Lengthening System was developed in partnership with Professor Baumgart. The product was launched in 1997. Since then, this innovative treatment concept has grown into a global success story. The Fitbone TAA Intramedullary Lengthening system is intended for limb lengthening of the femur and tibia. With appropriate pre-operative planning, it is possible to ensure good limb alignment so that the limb is correct at the end of lengthening.
The Fitbone™ Intramedullary Limb Lengthening System is intended for lengthening of the femur and tibia. It was first introduced in 1997 as one of the first all-internal motorized limb lengthening systems into the market. Paired with dedicated instrumentation, the system offers a minimally invasive, bone conserving approach for correcting limb length discrepancies and deformities.
Backed by more than two decades of clinically demonstrated performance, Fitbone’s electromagnetic technology delivers dependable, controlled distraction across a wide range of anatomies. Its reliability reinforces surgical confidence and supports consistently successful outcomes.
The Fitbone Limb Lengthening Family includes the legacy TAA femoral and tibial nails, as well as the next generation Fitbone Trochanteric Nail. The Fitbone Troch Nail is an antegrade femoral option designed for lengthening through the proximal entry point of the greater trochanter, which is needed to support the pediatric and small stature patient population with an LLD. Together, these solutions provide a comprehensive internal lengthening portfolio tailored to modern limb reconstruction needs.
Summary of Benefits
- Comfortable lengthening process facilitated with the small, lightweight and silent Control Set.
- Reliable feedback from the system throughout the lengthening process.
- Quick reintegration into daily routines.
- Short hospitalization.
- Minimal risk of infection.
- Little scarring.
“The potential advantages are many: fewer scars, improved aesthetics, better body image and psychological well-being, no irritation through pins and wires, reduced pain, uncommon infections, secondary axial deviation avoided, less joint stiffness, higher activity level during lengthening consolidation, faster rehabilitation, less risk of neurovascular compromise due to wire or screw insertion, and improvement in the ability to work during and after treatment.” 1
