Limb Lengthening Surgery, also known as Ilizarov Surgery, is an advanced orthopedic procedure used to increase the length of arms or legs, correct bone deformities, and treat limb length discrepancy. This technique is widely used to help patients regain balance, mobility, and confidence in daily life.

What is Ilizarov Surgery?

Ilizarov surgery uses a special external fixation device (Ilizarov frame) that is attached to the bone through thin wires and pins.

The bone is carefully cut (osteotomy), and then slowly and gradually stretched, allowing new bone to form naturally in the gap.

• Natural bone regeneration
• Correction of deformities
• Restoration of limb alignment

Conditions Treated with Limb Lengthening Surgery

• Limb length discrepancy (one leg or arm shorter than the other)
• Congenital limb deformities
• Post-traumatic bone shortening
• Bone infections (chronic osteomyelitis)
• Non-healing fractures (non-union)
• Bow legs or knock knees
• Short stature correction

How the Limb Lengthening Process Works

• Surgery – The bone is precisely cut and the Ilizarov frame is applied.
• Distraction Phase – The bone is gradually lengthened (about 1 mm per day).
• Swelling, deformity, or instabilityBone Formation – New bone grows in the gap naturally.
• Consolidation Phase – The new bone hardens and strengthens.
• Frame Removal – Once healing is complete, the frame is safely removed.

Benefits of Ilizarov / Limb Lengthening Surgery

• Accurate and controlled limb length correction
• Natural bone growth and healing
• Improves walking balance and posture
• Corrects deformities without bone graft in many cases
• Suitable for children and adults
• Long-term functional improvement
