The LON Method (Lengthening Over Nails)
The LON Method, is a procedure that lengthens leg bones using metal nails placed over them. It begins with surgical cutting of the bones, followed by nail placement. The bones are lengthened using the nail's motorized system.
How Is It Performed?
- Surgery: The leg bones are cut and a metal nail is placed over them.
- Bone Lengthening: The nail is gradually lengthened each day, and the space between the bones fills with new bone tissue.
- Monitoring and Control: The patient's condition is monitored regularly as the bones lengthen.
Advantages:
- Less Invasive: Requires a smaller surgical intervention than other methods.
- Faster Recovery: Patients can generally recover in less time.
Disadvantages:
- Risk of Infection: Placement of a metal nail may increase infection risk.
- Slow Recovery: Bone lengthening may generally take longer.

The LON Method: An Innovative Surgical Approach to Limb Lengthening and Deformity Treatment
The LON Method (Lengthening Over Nail), is a treatment used in limb lengthening surgery that has attracted attention as an important innovation in recent years. It was developed to lengthen shortened or deformed bones. LON has many advantages over traditional lengthening methods and is generally preferred when bones need lengthening. This article examines what LON is, how it works, its advantages and its applications in detail.
What Is the LON Method?
The LON Method, Lengthening Over Nail means that bone lengthening is performed over an internal nail, such as an Ilizarov nail or Precice nail . In this method, the metal nail used for bone lengthening is placed inside the bone, and lengthening is performed over it. LON provides greater stability during lengthening and accelerates patients' recovery.
How Does the LON Method Work?
In the LON method, a nail is first surgically placed in the area where the bones will be lengthened. It is inserted through the canal inside the bone to provide stability. Bone lengthening then begins by cutting a specific area of the bone. The nail's internal mechanism helps the bones separate and lengthen correctly during the process.
Lengthening is usually performed at about 1 mm per day. The bones begin to separate gradually, and new bone formation (osteogenesis) occurs in the gap. This process is carefully monitored to optimize recovery and functional outcomes.
Advantages of the LON Method
The LON method has many advantages over traditional lengthening techniques:
- Greater Stability:
An internal nail provides greater stability during bone lengthening. Because it is placed inside the bone, it helps protect the bones against external stresses. - Lower Risk of Complications:
Unlike external devices (such as an Ilizarov nail), LON results in fewer infection and wound-healing problems. The internal nail minimizes external intervention and reduces infection risk. - Aesthetic Advantages:
Because no device is externally visible during LON lengthening, the results are more aesthetically acceptable. This helps patients feel more comfortable and secure. - Faster Recovery:
Patients generally experience less pain during bone lengthening and recover faster. Internal nails cause patients fewer difficulties than external devices. - Controlled Lengthening:
Lengthening is performed in a controlled manner with LON. The mechanism on the nail allows precise adjustment of bone position and lengthening speed throughout the process, providing safer treatment.
Applications of the LON Method
LON may be used for various orthopedic and surgical conditions:
- Limb Shortening:
Congenital or trauma-related shortening can be treated with LON. Increasing bone length improves patients' function and appearance. - Height Lengthening:
People of short stature may undergo height lengthening for aesthetic or functional reasons. LON is an effective option used in height lengthening treatment. - Bone Deformities and Reconstruction:
Bone deformities, such as misalignment or bowing, can be treated. LON can lengthen bones and restore correct alignment. - Pathological Fractures and Trauma:
Limb deformities caused by fractures and trauma can be corrected with LON to achieve better functional and aesthetic results. - Leg Lengthening:
Walking difficulties, pain and aesthetic problems caused by short legs can be treated with LON. Restoring symmetry allows patients to move more comfortably.
Recovery with the LON Method
Recovery after LON bone lengthening may vary with the patient's general health, age and condition of the bone to be lengthened. In general, the process can be outlined as follows:
- Surgery:
First, an internal nail is surgically inserted into the bone. This is usually performed under general anesthesia and may take approximately 1-2 hours. - Bone Lengthening Process:
Bone lengthening begins through the mechanism placed on the nail. Usually, about 1 mm of lengthening per day completes the process within 1-2 months. - Rehabilitation and Physical Therapy:
Rehabilitation is important throughout bone lengthening. Exercises and physical therapy ensure that bones heal correctly. This process helps bones lengthen properly. - Bone Healing:
New bone forms during lengthening, and the bone eventually heals. Once lengthening is complete, the nail can usually be removed within 6-12 months.
Conclusion
The LON Method, is an effective and safe option for limb lengthening and deformity treatment. Its aesthetic advantages, rapid recovery and lower risk of complications distinguish it from traditional treatments. If you have limb shortening, deformity or similar orthopedic problems, LON can provide safe and successful treatment. However, a professional assessment by an experienced orthopedic specialist is important before starting this type of treatment.
