How is Ilizarov’s external fixation device applied?

In order to apply Ilizarov’s external fixation device, with the patient under anaesthesia, steel wires are introduced into the pathologic limb, which are then fixed in tension by circular structures made of steel.

These steel rings are then externally connected by threaded rods, hence forming a sustaining cylindrical framework around the limb.

In fact, the former basically constitutes the essence of treatment and can be likened to an “open plaster”, allowing access and monitoring of the skin and/or eventual existing lesions. The structure moreover allows correction, when necessary, of axial defects, but offers, at the same time, stability and support and the feasibility of crutch-assisted weight-bearing, hence movement.
