Fitbone

Advanced Internal Limb Lengthening

Fitbone™ Intramedullary Lengthening System

Fitbone™ is a fully internal, motorized limb lengthening system developed in Germany. Unlike traditional external frames, this advanced intramedullary technology operates entirely inside the bone, offering a more comfortable and cosmetically refined solution for height enhancement.

At Height Increase Info (HII), Fitbone is recommended for patients who prioritize medical precision, reduced infection risk, early mobility, and a more natural daily life during the lengthening journey.

Procedure Overview

How the Fitbone Method Works

Fitbone Surgery
01

Surgery & Implantation

The Fitbone nail is implanted inside the bone under general anesthesia. A small receiver is placed beneath the skin and connected to the nail. The procedure typically takes 1.5 to 2 hours.

Patients usually remain hospitalized for around 5 days and begin assisted standing and walking within 24 hours using a walker or crutches.

Daily Lengthening Process
02

Daily Lengthening Process

Around 5 days after surgery, lengthening begins. Patients use a handheld external transmitter placed over the skin receiver.

Three sessions per day result in approximately 1 mm of bone growth daily. Typically, 6 cm can be achieved in about 60 days and 8 cm in around 80 days.

Bone Growth Consolidation
03

Bone Growth & Consolidation

As the nail gradually expands, new bone tissue forms in the created gap. Once the target height is achieved, distraction stops and the consolidation phase begins, allowing the bone to harden and stabilize.

Healing progress is carefully monitored through regular X-ray imaging.

Physiotherapy Rehabilitation
04

Physiotherapy & Rehabilitation

Daily physiotherapy is essential during treatment. Stretching and strengthening exercises help prevent stiffness, maintain joint mobility, and allow muscles to adapt to the new bone length.

Rehabilitation continues throughout both distraction and consolidation phases.

Advantages

Why Choose Fitbone?

Designed for precision, comfort, and a more refined recovery experience compared to traditional external methods.

Fully Internal Technology

No external frames, reducing infection risk and improving overall comfort.

Minimal Scarring

Small surgical incisions lead to better cosmetic outcomes.

Early Mobility

Patients begin assisted walking shortly after surgery.

Motorized Precision Control

Controlled lengthening ensures consistent and predictable results.

Bidirectional Adjustment

The system allows both lengthening and controlled correction if needed.

Better Daily Comfort

No bulky external device allows more natural movement and lifestyle.

Height Potential

How Much Height Can Be Gained?

Femur Lengthening

Up to 8 cm

(3.1 inches)

Tibia Lengthening

Up to 7 cm

(2.7 inches)

The achievable increase depends on bone anatomy, muscle flexibility, nerve tolerance, and overall adaptation during the lengthening process.

Advantages

Why Choose Fitbone?

Fully Internal System

No external fixators and no pin-site infections.

Minimal Scarring

Only small incisions with improved cosmetic outcome.

Early Mobility

Assisted walking begins one day after surgery.

Precision Control

Motorized nail allows controlled and reliable distraction.

Bidirectional Capability

The system can lengthen and shorten if medically required.

Risks & Considerations

As with any surgical procedure, limb lengthening carries potential risks. These are managed through detailed planning and structured follow-up.

Is It Right For You?

Fitbone Eligibility

Fitbone™ is ideal for patients seeking a fully internal system without external frames, smaller scars, and greater independence during treatment. Candidates must be medically suitable and committed to daily physiotherapy, follow-ups, and structured rehabilitation.
