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.
