Treatment of fractures that have failed to heal, or that have healed in a poor position.
What is it?
Non-union is when a broken bone fails to heal after the expected time. Malunion is when the bone heals but in a poor position — bent, rotated or shortened. Both conditions cause pain, weakness and difficulty with function. The Ilizarov method can treat both: stimulating healing in non-union and correcting the position in malunion, often simultaneously.
Who needs it?
- Fractures that have not healed after several months
- Fractures with bone loss or infection preventing healing
- Healed fractures with significant deformity
- Failed previous surgery for non-union
- Atrophic or hypertrophic non-union
How is it treated?
The Ilizarov frame is applied and the non-union or malunion site is addressed — either by stimulating compression and movement to promote healing, or by correcting the deformity through gradual adjustment. Bone grafting may be added if needed.
What to expect
Treatment duration varies depending on the type of non-union and the amount of correction needed. The frame is worn until the bone heals. Physiotherapy helps maintain joint movement. Regular X-rays monitor healing progress.
Risks and Limitations
Like any surgery, this treatment carries risks. These can include pin-site infection, joint stiffness, delayed bone healing, and the need for further procedures. Results depend on age, general health, the condition being treated and following the treatment plan. Dr. Hoda will explain the risks that apply to you before you decide.
