Limb Lengthening Surgery Methods

Lengthening Over Nail (LON)

Minimum invasive, minimum scar, correct curvature legs simultaneously and established surgical method to minimize x-shaped leg occur. LON is a method first introduced in the mid-1990s by Dr. Paley. During 1st stage surgery, an intramedullary nail is inserted at the same time as the external fixator, so during the lengthening period intramedullary nail prevent angular deformity. And when lengthening is complete, the external fixator can be removed with the completion of the internal fixation(screw insertion). This method was a groundbreaking development compared to the original method that only involved the use of an external fixator (Ilizarov). Even today, many limb lengthening surgeons around the world use this method.


Lengthening And Then Nail (LATN)

Rehabilitation period shorten over 6 weeks compared to LON, possible to return back to everyday life quickly, abundant bone regeneration formation. In the case of LATN, during 1st stage surgery, only an external fixator is installed, and after full lengthening, during 2nd stage surgery, the external fixator is removed and an intramedullary nail is inserted. During 1st stage surgery, future space needed for the internal rod needs to be considered when determining the positions for the external fixator pins. Also, the correction process before 2nd stage surgery requires much knowledge and care from the doctor. Rather than simply using the Ilizarov, computer assisted fixator systems like the Hexapod or ORTHO SUV must be used for accurate correction. Also, since the intramedullary nail is inserted during 2nd state surgery, the fixation is much stronger, and the rate of callus production accelerates after 2nd stage. A large advantage of LATN is that bone formation is fast and because of strong internal fixation, compared to LON, patients can return to normal activity 2 or more months faster. Also, since it undergoes a correction process, precise bone alignment can be met. One drawback is that the amount of time wearing the external fixator may be 2 or 3 weeks longer than LON, because of the correction process.

LON (Lengthening Over Nail) and LATN (Lengthening And Then Nail) are hybrid techniques that includes the advantages of both external and internal fixation. However, even with this method, an external fixator must be worn during the lengthening period, so complications caused by external fixation cannot be avoided. In LON, since the external fixator and the intramedullary nail are installed at the same time, there is a risk of minor pin-site infections leading to Intramedullary infections(the risk can be reduced to nearly 0% with careful management). Intramedullary lengthening methods not involving external fixators can reduce this risk of infection, reduce pain and ugly scars and also reduce the mental stress experienced by patients. Hence, since 1959, the hopeful development of such methods was attempted, but clinical practices were minimal. Currently, clinically well known Intramedullary lengthening devices are Albizzia® (France), Fitbone® (Germany), ISKD® (Intramedullary Skeletal Kinetic Diatractor; Orthofix, USA), and PRECICE nail® (Ellipse, USA).


PRECICE Lengthening System

The PRECICE Lengthening System consists of a telescoping metal rod with a magnetic motor inside of it and the External Remote Controller (ERC). The internal nail is inserted through a small incision into the bone marrow cavity, and a patient lengthens the bone with the external remote controller.


Anesthesia Method for Limb Lengthening and Deformity Correction

Spinal anesthesia (regional) is used for surgery, and pain blocking is performed under ultrasonography for pain control. Patients sleep with self breathing and breathe on their own during the surgery. Brachial plexus nerve block (regional) is employed for upper extremity lengthening surgery and deformity correction. However, the choice of anesthesia for a patient is made by an anesthesiologist, and the methods may be adjusted for safety reasons.

Frequently Asked Questions

How much does Limb Lengthening Surgery cost?

You can find our Surgery Cost information here:

> Leg Lengthening Surgery Costs

How many centimeters can I gain after Leg Lengthening Surgery?

For cosmetic reasons, it is preferable not to lengthen over 7 cm per segment. We believe that safety and health of our patients need to come first. It is extremely dangerous and risky to attempt lengthening more than 7 cm. If a patient desires to gain a longer length we recommend to do surgery on both tibia and femur, for example, 6 cm on tibia, plus 7 cm on femur, total length of 13 cm. The flexibility of your legs is also important. The more flexible your legs are, the more relaxed you will be during the lengthening.

What is the recovery time after the surgery?

It depends on the surgery method, the total length of the lengthening, and the lengthening area (tibia vs femur), but it usually takes about 1-2 months.

When can I return to normal life after the surgery?

You can return to your normal life after 6-8 months from the surgery.

When do I remove the nails? What is the cost? How long do I need to stay for that?

You can come back after 1 or 2 years to remove the nails.
The cost of the removal is KRW 5,000,000 and you only need to stay 2-3 days.

When can I run after leg lengthening surgery?

When the new bone which forms is fully ‘consolidated’ you can return to any activities you were enjoying prior to limb lengthening surgery. Initially you will need to adjust to the new length of your muscles but it shouldn’t take you long. Also the muscles will be initially weaker but with exercising you will regain the strength.

When can I play competitive sports, such as, soccer, tennis, or basketball, etc, again?

It may take up to a year to go back to do competitive sports, such as, soccer, tennis, or basketball.

How are the scars from surgery?

We use a minimally invasive method to put the lengthening device and these scars are so small they are not very noticeable. It looks like a mosquito bite, and it gets less visible as time goes by.

When can I go back to my country after the surgery?

Once we reach the desired lengthening height, we remove the external fixators.
As soon as we remove the external fixator, you can go back to your country.

Can I get financing to help pay for the surgery?

Unfortunately, we do not provide financing.

How painful is the Surgery?

Usually, the first 1-2 days after limb lengthening surgery are painful but our hospital uses both anesthesias (8hrs) and ultrasound-guided selective nerve block (36 hrs), so most of our patients have been dealing really well with the pain; we have both general anesthesiologists and subspecialty pain anesthesiologists to control the pain. And we also provide enough medication to feel comfortable.
