Ilizarov
Ilizarov Frame Method
The original circular-frame external fixator method — workhorse of reconstructive limb lengthening for four decades.
How it works
Developed by Gavriil Ilizarov in the Soviet Union, this method uses a circular external fixator of rings and tensioned wires. The fixator remains in place for the full distraction and consolidation phases. While slower and more burdensome for the patient than internal methods, Ilizarov remains the most versatile technique for complex deformity correction, infected non-unions, and bone reconstruction — areas where internal nails alone are insufficient.

Frequently asked questions
What is an Ilizarov frame?
An Ilizarov frame is a circular external fixator made of metal rings connected by rods and tensioned wires that pass through the bone. Developed by Gavriil Ilizarov, it holds the bone segments while they are gradually pulled apart (distraction) to grow new bone. The frame stays on for the entire lengthening and consolidation period.
Is the Ilizarov method an external fixator?
Yes. The Ilizarov apparatus is the original circular (ring) external fixator. Unlike internal magnetic nails such as PRECICE, all of its hardware sits outside the leg, attached to the bone with wires and pins — which is why it allows fine adjustment but requires diligent pin-site care.
Ilizarov vs PRECICE — which is better for limb lengthening?
Internal nails like PRECICE are usually preferred for straightforward cosmetic lengthening because there is no external frame and recovery is faster. The Ilizarov frame remains the more versatile choice for complex deformity correction, infected non-unions, and reconstruction, where an internal nail alone is insufficient.
How long does the Ilizarov frame stay on?
The frame typically stays in place for the full distraction and consolidation phases — often around 20 to 40 weeks total, depending on how much length is gained and how quickly the new bone hardens. It is removed once imaging confirms the regenerated bone is solid.
