Abstract
BACKGROUND: Infected nonunion of the distal humerus represents a true challenge as the fragment is usually small and difficult for fixation. The aim of the present study is to assess the results of Ilizarov external fixator in management of infected nonunion of the distal third humerus. MATERIAL AND METHODS: Twenty-three patients with infected nonunion of the distal humerus were included in this study. The ages ranged from 19 to 58 years with an average of 35 years. Seventeen cases were males and 6 were females. All patients were treated by radical debridement and application of Ilizarov external fixator in one stage surgery. RESULTS: Bony union was achieved in all cases. Bone graft was required in 12 patients with hypotrophic nonunion. The external fixation time ranged from 4 to 9 months with an average of 5.6 months. Infection was controlled in all cases without recurrence during the period of follow up. The complications included pin tract infection in 7 cases, radial nerve injury in one case, elbow stiffness in 4 cases and refracture after frame removal in one case. CONCLUSION: Ilizarov external fixator is effective in management of infected nonunion of the distal humerus. The thin tensioned wires produce good grip in the small or osteoporotic bone fragments.
