Ilizarov Frame
Pronunciation: ee-lee-ZAH-rof frame
A circular external fixation device used for bone lengthening, deformity correction, and complex fracture management.
Full Definition
An Ilizarov frame is a specialized external fixation system consisting of circular rings connected by threaded rods and tensioned wires that pass through bone. Developed by Russian orthopedic surgeon Gavriil Ilizarov, this apparatus utilizes the principle of distraction osteogenesis to achieve bone lengthening and deformity correction. The frame allows for precise, gradual adjustment while maintaining stability and permitting weight-bearing. It is commonly used for limb lengthening, bone transport, correction of complex deformities, and treatment of nonunions and infected fractures.
Usage
Usage note: Named after Gavriil Ilizarov; capitalize as eponym. Distinguish from other external fixation systems.
