Treatment of traumatic forearm bone loss with Ilizarov ring fixation and bone transport

Bone loss in the forearm results from high-energy trauma or follows non-union with infection. Ilizarov methodology provides stable fixation without implantation of permanent foreign bodies while permitting wrist and elbow movement. We are reporting our experience using distraction osteogenesis in the treatment of traumatic bone loss in the forearm. From 1991 to 2000, 11 consecutive patients with traumatic forearm bone loss were treated with Ilizarov ring fixation. Records were reviewed retrospectively. All patients were contacted 2-10 years after surgery at the Ilizarov Clinic in Lecco, Italy. Eleven atrophic non-unions with bone loss were treated. The time from injury to Ilizarov treatment averaged 2.1 years. Follow-up averaged 6.2 years. The union rate with Ilizarov treatment alone was 64%. Thirty-six percent of the patients were converted to a hypertrophic non-union and underwent compression plating. The overall rate of union was 100%. There were four unplanned reoperations and no refractures, neurovascular injuries or deep infections. Three patients had significant limitations of wrist function. Nine patients described their function as excellent. Ilizarov fixation with bone transport is a viable treatment option for atrophic forearm non-unions with bone loss. Treatment resulted in ablation of infection, healing of atrophic non-unions with minimal complications and early extremity use.
