Ilizarov Apparatus
The Ilizarov apparatus (pronounced: il-ee-zah-rov) is a type of external fixation used in orthopedic surgery to lengthen or reshape limb bones; to treat complex and/or open bone fractures; and in cases of infected nonunions of bones that are not amenable with other techniques.
Etymology
The Ilizarov apparatus is named after the Soviet orthopedic surgeon Gavriil Abramovich Ilizarov, who pioneered the technique.
Description
The Ilizarov apparatus is a type of external fixator that is attached to the bone with thin metal wires. The bone is then cut and the apparatus is used to slowly pull the cut ends of the bone apart, which leads to new bone formation at the cut site. This process is known as distraction osteogenesis.
Usage
The Ilizarov apparatus is used in the treatment of many orthopedic conditions, including:
- Fractures that are not healing properly (nonunions)
- Infected nonunions, where the infection is resistant to other treatments
- Bone lengthening for individuals with limb length discrepancies
- Deformity correction in conditions such as clubfoot and knock knees
- Bone tumors that require bone resection
