Use of the Ilizarov external fixator in the treatment of patients with Ollier's disease.

Abstract

The authors present the results of treatment of 10 patients with Ollier's disease using the Ilizarov technique. The Ilizarov device was used to treat leg length discrepancy and to enhance the conversion of chondroma cartilage into normal mature bone, with no curettage and bone grafting. The mean duration of treatment was 9.4 months. This technique was highly efficient in treating the disease. It led to conversion of the abnormal cartilage into histologically mature bone in all patients. Some complications were seen, such as decreased knee mobility, which required prolonged use of the device. The Ilizarov technique is successful in treating patients with Ollier's disease despite some complications and the difficulty in using the technique.
