SUMMERY

3.  Born in soviet union.
 In 1950, sent to kurgan, siberia to
look after injured russian soldier.
 Inspiration –by sharft of bow harness
on hourse carriage.
 Using spoke of bicycle from local
bicycle shop , he devised ring
external fixator.
 Accidently he found new bone
formation radiologically in a patient
who turned compressing rods
between rings in distraction rather
than compression.
 He revolutionized the treatment of
difficulty musculoskeletal problems.
HISTORY

4.  Wires of 1.5mm or 1.8mm diameter are
passed percutaneously (through the skin)
through bones by means of a drill.
 The protruding ends of these wires are then
fixed to rings with special “wire-fixation”
bolts.
 These rings in turn are connected and fixed
to one another by threaded rods.
 Once it fixed , the ilizarov frame affords a
stable support to the affected limb.
 A CORTICOTOMY is then performed; it is
osteotomy where the perosteum of the bone
is preserved.
 Adjustment in the road produce compression
or distraction as desired between the bone
end , and simultaneously , deformities also
corrected.
 The ring fixator is removed at the end of the
treatment.
MECHANISM

5. The postoperative management of a patient requires frequent
contact and close monitoring by the surgeon.
Deformities and contracture cannot be allowed to presist or
progress.
The patient must be encourage to bear weight on the
lengthening limb.
Pin-or wire-site sepsis should be treated aggressively ;osteolysis
around an implant suggests that additional transosseous
fixation is needed.
PRECAUTION WHILE USING

6. Minimally invasive
Relatively easy application
Allow deformity to be corrected in 3 dimensions (axial , angular
and translation)
Patient is mobile through out course of treatment
Early physiotherapy prevent joint stiffness and concentration
Simple hard water removal
