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.

Leg Length Discrepancy
Most people have a slight difference in the length of their legs, but when the difference in leg length is significant it can cause problems with mobility and development. This is when it’s a medical condition known as leg length discrepancy, or LLD.
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.
Bone Dysplasia (Dwarfism)
Dwarfism 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.
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.
