Management of Distal Tibial Interosseous Osteochondroma: A Case Series and Review of Literature.

The interosseous part of the distal tibia is one of the regions in which osteochondroma can occur. Osteochondroma typically occurs among growing children and causes gradual ankle deformity by its pressure effect on the fibula. We presented six patients (Five boys and one girl with median age of 13 years old) with distal tibial interosseous osteochondroma. They were treated by a 180̊ fibular osteotomy around its longitudinal axis just proximal and distal to the lesion. All patients were treated without any complication except for one who developed non-union of the site of the fibular osteotomy. In the last follow-up, all the patients were pain-free, and no recurrence was reported. Various methods have been described for resecting interosseous osteochondroma of the distal tibia, with or without fibular osteotomy and with or without acute correction of ankle deformity during resection surgery. Still, there is no consensus over the best method for resecting such lesions.
