Can Limb Lengthening Fail?
Short answer
Limb lengthening can have problems, as any surgery can, but complete failure is rare. The main risks are slow or absent bone healing (non-union), the new bone hardening too early (premature consolidation), implant problems such as nail breakage, and joint stiffness. Our overall complication rate is about 1%, and we monitor every patient with regular X-rays so problems are found early.
What can go wrong
• Non-union: the new bone does not harden as expected. It is uncommon, and the risk is higher with smoking and some health conditions.
• Premature consolidation: the new bone hardens before the target length is reached, which can stop the lengthening early.
• Slow consolidation: the bone heals more slowly than planned, which lengthens the recovery.
• Implant problems: rarely, a nail can break or stop working.
• Joint stiffness and muscle tightness: the soft tissues have to stretch with the bone; physiotherapy helps prevent stiffness.
• Infection: possible after any operation; keeping wounds and pin sites clean lowers the risk.
See the full list in Complications of limb lengthening.
How we reduce the risks
• Staying within safe limits: up to 8 cm in the femur and 6 cm in the tibia.
• A controlled speed of about 1 mm a day.
• Regular X-ray checks (every 1 to 2 weeks while lengthening) let the surgeon slow down or pause if needed.
• Physiotherapy 6 days a week during your stay, and free, unlimited remote follow-up afterwards.
• A full health review before surgery, including smoking and conditions such as diabetes.
What happens if there is a problem
When something goes wrong, it usually shows up early on the X-rays, and we can respond by changing the lengthening speed or the physiotherapy, or with an additional procedure. On top of the basic complication insurance that every health tourist must have, we cover complications related to our surgery for the first 3 months while you are under our care. Known natural risks of lengthening are explained in Complication cover.
Your part in a good result
Not smoking, following the physiotherapy programme and attending every check-up are the most important things you can do. See physiotherapy after limb lengthening and the recovery timeline.
Warning signs to report quickly
• Pain that is new or getting worse, or redness, warmth or fluid around a wound or pin site.
• Fever.
• Numbness, tingling or weakness in the foot.
• Loss of joint movement despite physiotherapy.
• A sudden change in the leg, or a feeling that the device has stopped working.
During your stay, tell the team at once. After you go home, contact us through your remote follow-up.
Why the speed matters
Lengthening too fast can stretch nerves and soft tissues too quickly and leave the new bone weak; lengthening too slowly can let the bone harden too early. That is why we lengthen at about 1 mm a day and check X-rays every 1 to 2 weeks, adjusting the speed if needed.
Risk factors you can change
• Smoking slows bone healing; stop before surgery.
• Skipping physiotherapy increases the risk of joint stiffness.
• Putting more weight on the leg than allowed increases the risk of implant problems.
• Missing X-ray checks delays the detection of problems.
Long-term outcome
When the new bone has consolidated and the nail is removed, the gained length is permanent. Walking without crutches usually comes at around 4 to 6 months, and sport at around 9 to 12 months. See running after limb lengthening.
A realistic view of risk
No surgeon can promise that nothing will go wrong. What a good team can do is choose suitable patients, stay within safe limits, monitor closely and act quickly when something changes. Most issues during lengthening are small and are solved by adjusting the speed or the physiotherapy. Serious complications are rare, and we explain each of them before surgery so you can make an informed decision.

FAQ
How often does limb lengthening fail?
Complete failure is rare. Our overall complication rate is about 1%.
What is non-union?
Non-union means the new bone does not harden as expected. It is uncommon, and smoking increases the risk.
What is premature consolidation?
The new bone hardens before the target length is reached, which can stop the lengthening early.
Can the nail break?
Rarely. Staying within safe limits and following the weight-bearing instructions reduces the risk.
How do you find problems early?
With check-ups and X-rays every 1 to 2 weeks during lengthening.
Are complications covered?
We cover complications related to our surgery during the first 3 months while you are under our care. Known natural risks of lengthening are not covered. See Complication cover.
Can the height gain be lost later?
No. Once the new bone has consolidated, the gained length is permanent.
