Hypertrophic non-union of a tibial shaft fracture is BEST managed by:
- A Bone grafting with cast immobilisation
- B Exchange intramedullary nailing without bone graft ✓
- C Ilizarov ring fixator with bone graft
- D Locked plating with bone graft
Explanation
Hypertrophic non-union indicates biological capacity for healing but inadequate mechanical stability — the 'elephant foot' pattern on X-ray shows rich callus bridging. Exchange intramedullary nailing (reaming and inserting a larger nail) provides the required stability and stimulates endosteal healing through reamings; additional bone graft is not needed. Atrophic non-unions, lacking biology, require both stability AND bone grafting. Ilizarov fixation is reserved for infected or atrophic cases with bone loss.
