Femur Limb Lengthening (LON)
The LON method is a safe and effective technique primarily employed for femur lengthening, although it can be used for other long bones as well. This procedure is widely recognized for its effectiveness in treating conditions such as limb length discrepancy, dwarfism, or specific congenital abnormalities.
So, what is the Lengthening Over Nail (LON) method?
The LON method is a two-stage surgical process involving the placement of an intramedullary nail and an external fixator. This technique marries the benefits of both external and internal fixation methods, thereby maximizing stability, facilitating the lengthening process, and it is costy effective.
How does the LON method work?
First Stage: The procedure begins with the surgeon making an incision and placing an external fixator after performing an osteotomy (a surgical operation where a bone is cut to shorten, lengthen, or change its alignment).
This fixator, attached to the bone with pins, plays a crucial role in the gradual lengthening process.
Second Stage: Following the desired lengthening using the external fixator, the surgeon inserts an intramedullary nail into the marrow cavity of the bone. This nail provides internal support and maintains the newly achieved length while allowing the bone to heal.
What are the benefits of the LON method?
Controlled Lengthening: The external fixator allows for gradual and controlled lengthening of the bone.
Stability: The insertion of the intramedullary nail provides additional internal stability, facilitating the bone healing process and minimizing complications such as fractures or deformities. Therefore it is safe to bear more weight compared to magnetic nails.
Comfort: The nail insertion allows for the removal of the external fixator at an earlier stage, enhancing patient comfort and mobility during the healing period.
Improved Aesthetics: As the external fixator can be removed earlier, it reduces the overall time a patient has to spend with external hardware, offering better aesthetic results.
Despite its many advantages, it’s important to remember that the LON method, like any other surgical procedure, may not be suitable for all patients. The choice of technique should be based on an individual’s specific condition, overall health, and surgeon’s recommendation.
In conclusion, the LON method represents a significant stride forward in the world of limb lengthening and correction. The combination of external and internal fixation methods in this approach ensures both the safety and efficacy of the procedure, giving patients a more comfortable, aesthetically pleasing, and complication-free healing process.
Remember, as with any medical procedure, the most important step is finding a skilled and experienced surgeon you can trust. Don’t hesitate to ask questions and make sure you understand all the aspects of your treatment plan before you proceed.
