The Ilizarov technique, developed by Gavriil Ilizarov, is an orthopedic method for external fixation of fractures and managing various pediatric orthopedic conditions using distraction osteogenesis to promote bone growth. It offers several advantages, including enhanced stability, less risk of infection, and potential for limb lengthening. The technique involves surgically attaching a ring fixator to the limb, followed by precise adjustments to facilitate bone healing and regeneration.

1. Ilizarov Technique
There are many bone - fracture fixation techniques devised by numerous
scientists. Those techniques have helped people in reducing the severity of the
condition and ensuring a better lifestyle after trauma. One such technique is the
Ilizarov Technique that is used in orthopedic surgeries for external fixation of the
fracture. This amazing technique was developed by an orthopedic surgeon from
the Soviet Union named Gavriil Abramovich Ilizarov.
What is the Ilizarov Method?
Ilizarov technique is known to effectively manage certain pediatric orthopedic
conditions including trauma, deformities, defects, deficiencies of limb, and
infections. This method promotes bone growth using a specialized device and by

2. distraction osteogenesis. External Fixation Device is most commonly used in
Ilizarov technique.
Ilizarov technique has made it possible to treat certain conditions that were
difficult or even sometimes impossible to treat. The use of external fixator devices
in this method is also known to be effective in minimizing the prevalence of
nonunion.
Principle Behind Ilizarov Technique
Ilizarov technique works on the principle of "tension stress" where gradual
distraction results in the stimulation of bone production and neogenesis. This
method reduces the need for internal fixation and supplemental bone grafting.
Tissue-sparing cortical osteotomy-osteoclasis technique is used in this method
that results in the preservation of osteogenic elements in the limb. It is noticed
that the use of the Ilizarov method results in the regeneration of good-quality
bone.
Clinical Applications of Ilizarov Technique
Ilizarov method is used for the fixation of fracture in both adult and pediatric
patients having open fractures along with severe wound and/or soft tissue
contamination. External Fixation Device is most commonly used during the
application of the Ilizarov method.
How is Ilizarov Technique performed?
To fix the Ilizarov fixator to the limb, surgery will be required. Wires are passed
percutaneously through the bone of the surgery site using a drill. Now, metal
rings are attached using protruding ends of wires. The rings are applied to encircle
the limb and tensioned to enhance stability.

3. After this, corticotomy is performed which involves cutting off the cortex of the
bone. During corticotomy, the periosteal and endosteal blood supplies are kept
intact because they play a major role in osteogenesis. Distraction begins after 5 to
10 days by turning the nuts to 0.25mm on metal rods. This is done four times per
day to achieve a total distraction of 1.0mm daily. This will result in osteogenesis
with continuous distraction.
After stopping the distraction, the frame is kept attached to allow hardening of
the new bone.
What are the Advantages of the Ilizarov Technique?
Ilizarov method is useful for fracture fixation in both adults and children. It has
many benefits:
● The modular design of the Ilizarov apparatus can be customized to meet
the needs of each individual.
● It is admired for providing enhanced stability and distributing the stress
evenly across the corticotomy along with the distraction gap.
● The frame of the Ilizarov technique is strong enough to bear optimum
weight while allowing the patient with his/her day-to-day activities. It is
also known to help build muscle strength while preventing joint stiffness.
● Ilizarov method involves the fixation of rings and wires only to the bone
without any requirement of other skin incisions. Thus, the risk of bleeding
and infection to surrounding tissues is reduced.

4. ● It ensures proper hold on the fractured bones and in case of non-unions,
provides significant compression.
● This method can also be used for limb lengthening and regeneration of
bone that is lost due to trauma, infection, or tumor.
