Ilizarov Fixator in the Management of Benign, Malignant and Complicated Cases of Bone Tumours

Abstract

Objective: evaluate the Ilizarov fixator in the management of bone tumours regarding the duration and the ease of the procedure, the outcome and the complications. Methods: This study was done at the Department of Orthopedic surgery in Ain Shams University Hospitals. 15 patients with benign or malignant tumours were treated by resection followed by bone and soft tissue reconstruction and Ilizarov circular fixator in January 2012-April 2013 and followed up till July 2014. Results: Follow-up was done with a mean period of 21.7 (14-28) months. Adjustment of the frame was done as required. As regards malignant tumours, the disease free survival has a mean of 22.8 (12-30) months. 2 patients developed local recurrence. The overall survival was a mean of 25.8 (13-30) months. 1 patient died as a result of chemotherapy. The MSTS score was 50% to 100% with a mean value of 84.6%. ASAMI-bone score was excellent in 53% of the cases, good in 2 cases, fair in 1 case but poor in 4 cases. ASAMI-function score was excellent in 53% of cases, good in 33% of cases, fair in 1 case and poor in 1 case. The adverse effects were 7 problems, 5 obstacles and 6 complications according to Paley’s classification. Conclusion: Biological reconstruction using Ilizarov circular fixator should be considered safe and effective in the management of benign and low grade malignant tumours, and a salvage treatment in case of failure of other methods of limb salvage.
