Method of classification of the lower leg of MHE patients depending on the location of the exostosis. Figure A shows a patient in group A who have lesion of exostoses both the proximal and distal tibiofibular joints of the lower leg. Figure b shows the patient classified as group B that only have the exostoses involving the proximal tibiofibular joint of the lower leg. Figure c shows a radiograph of a group C patient with only the distal tibiofibular joint invasion. Figure d shows a group D that have lesion without both proximal and distal joint involvement
