LON Method

A cost-effective solution for advanced limb lengthening

The LON (Lengthening Over Nails) method is a popular limb lengthening technique that combines the use of intramedullary nails and external fixators. This method is preferred for its low cost, low risk, high success rate, and safety.

The procedure begins with the placement of an internal nail within the bone marrow by the surgeon. This nail is then attached to an external fixator during the distraction (lengthening) phase. Patients are able to walk during this phase with the external fixators on their legs. After the desired height is achieved, the external fixators are removed with minor surgery and the internal nails remain in the legs until full bone consolidation is achieved.

The LON method uses a telescopic monolateral external fixator system, made of biocompatible titanium and aluminum alloy, which is highly mechanically stable to bear the whole body weight. Additionally, it is MRI compatible and considered the most advanced extension system among its equivalents. Its minimalist design makes it easier to move during the lengthening process, offers a smoother lengthening experience, and allows patients to return to daily life earlier after surgery.

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.

Step-by-Step to LON method limb lengthening surgery

  • Day 1: Arrival in Istanbul and rest at the hotel

  • Day 2: Meeting with the Doctor, examination, and preoperative tests

  • Day 3: Surgery day (2-3 hours)

  • Day 4: Post-surgery care in the hospital room

  • Day 5: First steps after surgery

  • Day 6-7: Rehabilitation in the private hospital room with bed exercises and short walks

  • Day 8: First lengthening

  • Day 9: Discharge from hospital

  • Day 10: Beginning of physiotherapy and exercise program

  • Day 60-80: Distraction Phase (Lengthening and Physiotherapy)

  • Day 70-90: External fixator removal (LON Method)

  • Day 70-150: Bone Consolidation and Transition to Normal Walking

  • Day 150-365: Bone Consolidation and Full Recovery

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 clinic, 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.
