Limb Reconstruction and Lengthening

What is the Combined (LON) System Method? With the combined method, in bone and lengthening surgery, closed nails and a fixator system that provides extension from the outside are applied together. The ‘LON’ methodology is highly preferred by our patients for these simple reasons: • High reliability, in comparison to classical external methods. Intramedullary nails add more stabilization to the bone. • Early removal of external devices, which allows earlier return to regular daily life activities. How does this method work? Now, the limb lengthening mechanism in LON methodology works with two devices, an internal intramedullary nail that is attached to a mono-lateral type external fixator. Once the LON apparatus is surgically attached to the patient’s legs; soon after 3-5 days of post-surgery hospitalization, the lengthening period begins at the hospital, whereby the external fixator is elongated or distracted by 1 mm per day, allowing the patient’s bone to separate, with the intramedullary nail inside their bones. Step by step guide to LON method – Lengthening begins after 4-5 days since the operation. The lengthen bones 1 mm / day. – Lengthening takes around 2-3 months (usually 1 mm / day. For example, 6 cm takes 2 months, and 7 cm takes 70 days) depending on the lengthened amount – Another 2-4 weeks pass before slight consolidation is visible on x- rays. Then external fixators are removed. – 1-1.5 yrs (or less, if bone consolidation is fast) after external fixators are removed, intramedullary nails can also be removed because at this time the bone is fully consolidated – It is possible to walk during the entire period of fixation, although with some difficulties and limitations. What is the maximum recommended amount of lengthening? 1. Femurs (Thighs): 6 – 8 cms OR 2. Tibias (Calf’s): 5 – 7 cms #lengtheningovernail #lenghtening #limblengthening #leglengthening #leglengtheningsurgery #legs #orthopedic #medical #surgery #precice #orthopedicsurgery #precicestryde #externalfixator #lenghtening
