Fitbone Trochanteric
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.
Precision
