Magnetic intramedullary nail – a modern method of limb lengthening

Just a few years ago, cosmetic limb lengthening was primarily associated with external fixators and a long, demanding treatment process. Today, thanks to advances in orthopedic technology, it is possible to perform surgical limb lengthening in a much more comfortable and predictable manner. One of the most cutting-edge solutions is the PRECICE Intramedullary Limb Lengthening System—a fully internal bone lengthening system currently considered the gold standard in cosmetic procedures.

This method is based on the biologically proven process of distraction osteogenesis, which involves the controlled formation of new bone tissue by gradually moving bone fragments apart after the bone has been cut.

What does the procedure involve?

During the procedure, the surgeon performs a precise osteotomy (a controlled cut in the bone) and then inserts a special intramedullary nail into the bone. The entire implant is located inside the bone—there are no parts protruding outward or metal pins passing through the skin.

After a few days, the gradual lengthening phase begins. The patient uses an external magnetic controller to activate the mechanism in the implant. The standard rate of lengthening is approximately 1 mm per day. During this time, the body:

• generates new bone tissue in the resulting space,
• adapts muscles, tendons, and neurovascular structures,
• is gradually adapting to the new length of the limb.

The process is regularly monitored through follow-up examinations, which allows us to maintain full control over the safety of the treatment.

Limb Lengthening Using a Magnetic Field

Limb lengthening using a magnetic field is a colloquial term for a method that utilizes the PRECICE internal telescopic intramedullary nail. The magnetic field does not act directly on the bone and does not lengthen it on its own. It is used to activate the mechanism of the implant placed inside the femur or tibia.

Leg lengthening using a magnetic field proceeds at a planned rate—typically about 1 mm per day—although the doctor may adjust this rate depending on the healing process and the tissues’ response. Progress is assessed during follow-up visits and X-ray examinations. This allows for monitoring the formation of new bone and adjusting further treatment accordingly.

Since the implant is located entirely inside the body, the method does not require the use of an external frame or pins that penetrate the skin. However, it does not eliminate the risks associated with surgical procedures and the bone-lengthening process. Regular physical therapy remains an important part of the treatment, as it helps maintain joint mobility, muscle flexibility, and a normal gait pattern.

Why is the magnetic method safer?

The biggest difference compared to external techniques is the absence of permanent entry points for infection. Since the implant is located entirely within the bone, there are no points where metal components penetrate the skin. This significantly reduces the risk of infection and inflammatory complications.

In addition:

• the scars are limited to small surgical incisions,
• There is no need for daily maintenance of the pins,
• The treatment is more discreet and less stressful.

In the case of cosmetic leg lengthening, where the procedure is performed on healthy individuals, minimizing risk is of particular importance.

Stages of treatment

The entire process can be divided into three main phases:

1. Surgery and nail implantation – a single surgical procedure.
   2. Lengthening (distraction) phase – lasting several weeks, depending on the planned increase in height.
   3. Consolidation phase – maturation and strengthening of the new bone, combined with intensive rehabilitation.

Physical therapy plays a key role in maintaining proper range of motion in the joints and preventing contractures. With the magnetic method, it can be performed without the limitations posed by the use of external equipment, which promotes a faster return to fitness.

Who is this method for?

The magnetic intramedullary nail is most often chosen by people who:

• are considering cosmetic procedures to increase their height,
• expect maximum safety and state-of-the-art technology,
• want to avoid visible external devices,
• value comfort and discretion in their treatment.

Final eligibility always requires an individual consultation with an orthopedist, an analysis of imaging studies, and an assessment of the patient’s overall health.

Leg Lengthening Using a Magnetic Field vs. Increasing Height in Adults

Once natural bone growth has ceased, bone length cannot be increased through exercise, supplements, or hormone therapy. Increasing height in adults requires surgical intervention, which allows for the controlled lengthening of the femur, tibia, or both of these bone segments.

Every height-increasing procedure requires prior qualification, including an orthopedic examination, imaging tests, gait analysis, and an assessment of overall health. Surgical height increase is a long-term process that does not end with the procedure itself—it also involves gradual lengthening, mineralization of the new bone, and rehabilitation.

The achievable result—the ultimate increase in height in adults—is determined on an individual basis, taking into account factors such as body proportions, tissue elasticity, and patient safety.

Summary – Key Points

• a modern, fully internal bone lengthening method,
• based on distraction osteogenesis,
• no pins and a lower risk of infection,
• greater comfort and a more aesthetically pleasing treatment experience,
• the ability to promote controlled and precise growth.

If you are considering surgical limb lengthening and want to find out whether the magnetic method is right for you, the first step should be a consultation with a specialist. A personalized treatment plan allows us to determine a safe range of lengthening and realistically plan the entire process—from surgery to a full return to normal activity.
