Circular External Fixator Models Compared

Ilizarov vs. Hexapod External Fixators

It is important to know how these devices help bones heal. Ilizarov circular external fixators and hexapod external fixators are two main choices. Both use rings to hold bones, but each has special features. Ilizarov fixators give strong support for up-and-down and bending forces. This helps bones heal when they need to stay still. Hexapod fixators use six struts for careful changes. These systems are stiffer when twisting bones. This helps with hard bone problems. You can use good hexapod fixators for fixing bone shapes and breaks.

Here is a table that shows how stiff each device is:

Fixator Type

Rigidity Characteristics

Ilizarov

Higher rigidity in axial and bending loading

Hexapod

More rigid in torsional loading

Cardan Joints

Significant 'toe-in' laxity under various loads

Ball-and-Socket

Minimal laxity, greater rigidity under axial load

Tip: Pick the device that fits your patient’s needs. Ilizarov fixators are good for steady support and healing. Hexapod systems are better for hard bone fixes and making bones longer.
