PRECICE Nail for Limb Lengthening

Also known as: magnetic lengthening nail, PRECICE, limb lengthening.

What is the PRECICE nail for limb lengthening?

The PRECICE nail is a magnetic lengthening nail that is used for correction of limb length discrepancies and deformity. Unlike traditional limb lengthening techniques which rely on external fixators, the PRECICE nail is an all-internal technique that provides early return of motion, less scarring, and better patient tolerance.

What happens during the procedure?

A surgery is performed to place a metal rod (nail) inside the affected bone.  This is done through multiple small incisions. The patient then uses a handheld magnetic transducer over the nail, which turns a motor inside the nail resulting in gradual limb lengthening over several weeks.

Is any special preparation needed?

Not all patients are candidates for this technique, depending on age and deformity. Your surgeon will obtain multiple radiographs, examine your joint stability, and identify and risk factors that you may have before deciding whether this technique is appropriate.

Bone Dysplasia (Dwarfism) Dwarfism (also known as achondroplasia) is a type of short stature. There are hundreds of different medical conditions that can affect ultimate size and/or the growth of an infant.
Fibular Hemimelia The fibula is the outer bone of the two bones that make up the lower leg and connect the ankle to the knee. When part or all of the fibular bone is missing, this can be due to a rare birth defect known as fibular hemimelia.
Congenital Femoral Deficiency The femur is the upper leg bone that connects the knee to the hip. In some children, a birth defect causes the femur to be shorter than it should be. This lead to other developmental issues, such as deformity and instability of the hip and knee. Congenital femoral deficiency typically impacts just one femur, though it can affect both.
Tibial Hemimelia The tibia is the inner bone of the two bones that make up the lower leg and connect the ankle to the knee. When part or all of the tibial bone is missing, this can be due to a rare birth defect known as tibial hemimelia.
ILIZAROV Treatment/Technique Ilizarov treatment/technique is a method used for correcting unequal or deformed limbs. It can also prevent amputation in some instances. It’s used to treat problems ranging from growth plate fractures to congenital limb deformities to broken bones that didn’t heal properly.
Taylor Spatial Frame™ The Taylor Spatial Frame is a medical device known as a circular external fixator. It’s a device that surrounds the leg or arm and gradually increases the length of the extremity in addition to correcting deformity.
