Limb lengthening is a specialized orthopedic procedure designed to increase the length of a person’s legs – most commonly the femur (thigh bone) or tibia (shin bone). This advanced technique is performed for both medical and cosmetic reasons, and has become increasingly common among patients seeking either functional correction or an improvement in self-esteem.
How the Procedure Works
Limb lengthening involves surgically cutting the bone and gradually separating the ends using either an internal nail (like the PRECICE system) or an external fixator. New bone tissue naturally forms in the gap, and the leg is lengthened slowly over time.
The process includes:
- Surgical implantation of the device
- Distraction phase (bone is gradually lengthened, usually 1 mm per day)
- Consolidation phase, where the new bone hardens
- Rehabilitation with structured physiotherapy
The full treatment and recovery process may take several months.
How Much Height Can You Gain?
The achievable height gain depends on the bone being treated and the individual’s condition:
- Femur (Thigh Bone): Typically adds 6–8 cm, with some patients reaching up to 9 cm
- Tibia (Shin Bone): Usually adds 5–6 cm, sometimes up to 7 cm
- Both Femur and Tibia (in staged procedures): Combined gain can reach 14–15 cm over time
These figures are approximate and depend on patient-specific factors like bone quality, soft tissue elasticity, and rehabilitation progress.
Why People Choose Limb Lengthening
- Medical reasons: To correct leg length discrepancies due to congenital issues, injury, or illness
- Psychological/Personal reasons: For those with height dysphoria or a strong desire for increased stature
- Reconstructive needs: After trauma or surgery where bone segments are missing
Who Is Eligible?
This is a serious orthopedic procedure and not suitable for everyone. Suitable candidates are typically:
- In good overall health, both physically and mentally
- Have closed growth plates (usually over 18 years old)
- Are non-smokers, to promote healing
- Understand the commitment to recovery and physiotherapy
- Have realistic expectations and are fully informed
All patients require a detailed medical assessment to determine eligibility and safety.
