LON Method
A cost-effective solution for advanced limb lengthening
The LON (Lengthening Over Nails) method is a highly preferred limb lengthening technique in recent times due to its affordability, comfort, and safety. This method involves using both intramedullary nails and external fixators. Hence it is also referred to as the combined method.
​
What makes the LON method unique compared to other methods is the internal nail that the surgeon places inside the bone marrow. This nail stays attached to the external fixator during the distraction (lengthening) phase, and after the lengthening is completed, the external fixators are removed with a minor surgical procedure. The internal nails remain in the bones until the newly formed bones have fully consolidated, allowing patients to resume their daily activities within 3 to 4 months after surgery.
The LON method utilizes a telescopic external fixator system made of biocompatible materials, providing both comfort and stability. This system is MRI-compatible, allowing for non-invasive monitoring during the healing process. Its minimalist design allows for easier movement and a smoother experience, enabling patients to return to their daily activities faster.

Advantages of LON Method
-
Allows patients to achieve significant height increase of up to 6-7 cm in the tibia and 8-9 cm in the femur
-
Short-term external fixator usage, typically between 70-90 days.
-
Allows patients to walk during the lengthening phase, which helps speed up recovery
-
Patients can start normal walking within 4-5 months after the surgery
-
Leaves fewer surgical scars than fully external methods, such as Ilizarov
-
Considered safe and affordable
Disadvantages of LON Method
-
Requires regular dressing at pin sites to prevent the risk of infection
-
Causes more scarring than internal methods
-
External fixators may cause discomfort

Lengthening Process in the LON Method
​In the LON method, the lengthening process is done 4 times a day, and 0.25 mm lengthening is provided in each process. Thus, the patient gains 1 mm in a day, 3 cm in 30 days, 6 cm in 60 days, and 8 cm in 80 days.
​
The lengthening process starts 3 days after the surgery at the hospital. The healthcare team performs the first lengthening process and teaches the patient how to do this process every day.

Is the LON method the right choice for me?
The LON method is a highly advanced and effective option for limb lengthening with treatment duration that is comparable to other leading methods such as Precice 2. It offers many advantages such as the ability to walk during the lengthening phase, a faster return to daily life, an affordable cost, and precision. However, it does require proper post-surgery care and rehabilitation.
At our practice, we provide exceptional care and support to ensure a smooth recovery. Our team of experts will work with you to determine if the LON method is the best choice for you, taking into consideration your individual needs and goals. We provide a thorough comparison of different methods available, so you can make an informed decision and have peace of mind.
