Limb Lengthening

The Ilizarov method can be used to lengthen a foreshortened bone. In order to accomplish this, the Ilizarov fixator is applied to the extremity and the bone is broken between rings using a variety of specialized techniques.

The controlled breaking of the bone is known as an “osteotomy” or “corticotomy”.

After waiting about a week, lengthening begins at a rate of ¾ to 1 millimeter per day. Slow gradual lengthening is accomplished by moving the rings progressively apart (by distracting the ring connectors). Bone forms in the distraction site by a process known as distraction osteogenesis.
