Ilizarov surgery, also known as distraction osteogenesis, is a technique used to lengthen or reshape bones using an external fixator device.
1
Fixator Placement
Metal rings or pins are attached to the bone above and below the area to be lengthened, and an external frame is assembled around the limb.
2
Gradual Distraction
Over several weeks or months, the fixator is adjusted to gradually separate the bone segments, stimulating new bone formation in the gap created.
3
Consolidation Phase
After achieving the desired length, the bone segments are allowed to consolidate and heal.
4
Fixator Removal
Once the bone has fully healed, the external fixator is removed, and rehabilitation begins.
Ilizarov surgery can add several inches to a person's height, improving self-confidence and overall stature. The technique can also correct deformities such as limb length discrepancies or angular deformities. Ilizarov surgery minimises soft tissue trauma compared to traditional bone lengthening techniques, reducing the risk of complications and promoting faster recovery. Its circular external fixator allows precise, gradual bone distraction with enhanced stability. A structured rehabilitation programme supports bone regeneration, muscle adaptation and safe return to daily activities.
Device Maintenance
Patients or caregivers must follow instructions for cleaning and maintaining the external fixator device.
Physical Therapy
Rehabilitation focuses on gradually increasing weight-bearing and restoring function in the lengthened limb.
Monitoring
Regular follow-up appointments with the orthopedic team are necessary to monitor bone healing progress and adjust the fixator as needed.
