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).

Frequently Asked Questions

How much does Limb Lengthening Surgery cost?

How many centimeters can I gain after Leg Lengthening Surgery?

For cosmetic reasons, it is preferable not to lengthen over 6-8 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 femurs more than 8 cm and tibia more than 7 cm. If a patient desires to gain, for example, something between 10-15 cm, it is more reasonable to get 5-8 cm on femur, then later 5-7 cm on tibia, rather than attempting to lengthen 10 cm on one bone section. The flexibility of your legs is also important. The more flexible your legs are, the more relaxed you will be during the lengthening.

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.

How painful is leg lengthening surgery?

Insertion of the nails and surgical breaks of the bones is painful but not as much as when the leg is broken in an accident. You will require painkillers post surgery and during the lengthening certainly. Our experience is that the requirement for pain relief in limb lengthening surgery is moderate compared to other procedures in limb reconstruction surgery.
