Quadrilateral Limb Lengthening
Reach your dream height in a single surgery.
At LiveLifeTaller, we offer one of the most advanced and effective forms of limb lengthening: Quadrilateral Surgery — the simultaneous lengthening of both the femur (thigh) and tibia (shin).
Why lengthen both bones at once?
With just one surgery and one anesthesia session, you can achieve up to 14–16 cm of height gain in about 3 months — safely, efficiently, and in full control.
In comparison, lengthening the femur and tibia in separate surgeries can stretch the overall process to 1.5 years before full mobility is restored.
Maximum comfort meets high-tech innovation
The Fitbone method is a fully internal, motorized German system. A titanium nail with an internal motor is implanted inside the bone and controlled externally with a wireless remote.
In a Quadrilateral Fitbone procedure, two Fitbone nails are implanted at once — one in the femur, one in the tibia.
Key benefits
- ✅ Fully internal — no external fixators
- ✅ Minimal, aesthetic scarring with cosmetic incisions
- ✅ Normal life: showering, wearing clothes, sleeping on your side
- ✅ Controlled daily lengthening via remote — precise and pain-free
- ✅ Proportional results — both bones grow in harmony
- ✅ Less tension on muscles — smoother healing and better comfort
Because the total length gain is split between two bones, each bone regenerates over a shorter distance, leading to faster, safer, more comfortable healing.
Estimated recovery timeline
- Basic mobility: within 3–4 months
- Athletic activities & full strength: within 8–12 months
(Recovery times vary depending on the individual.)
Intelligent combination for stability and value
The Hybrid method is ideal for patients who want to combine the comfort of modern internal lengthening with the mechanical stability of external fixation — all tailored to their physical condition, height goal, and budget.
With this method, one bone is lengthened with Fitbone, and the other with the trusted LON technique (which combines an internal implant with an external fixator).
Example combination
- Femur with Fitbone — full discretion and freedom
- Tibia with LON — effective, but with visible external frame
(or the reverse, depending on medical evaluation)
Benefits
- ✅ More affordable than using Fitbone for both bones
- ✅ One side remains fully comfortable — no external hardware
- ✅ The other side is effective with an external fixator
- ✅ Up to 14–18 cm of height gain still achievable
- ✅ Same medical support, same physiotherapy, same safety standard
Although the LON side involves a visible fixator and some limitations (especially for showering or sleep positions), the overall experience remains significantly more comfortable than double LON.
Why active recovery still matters
Whichever Quadrilateral option you choose, both bones — and the muscles, nerves, and joints around them — are lengthening at the same time. Our 90-day rehabilitation programme with the AlterG anti-gravity treadmill is designed exactly for this scenario.
