Our report concerns twelve cases with chronic injuries of the malleolus caused by traction injuries during sports. All the cases showed slight tenderness, swelling, and limping. Radiograph showed accessory ossification center and MRI demonstrated avulsion fracture of the apophlyseal cartilage and fragmentation of the accessory center. In this series we attempted the treatment suggested by Ogden. All the cases were treated with cast fixation, following one month rest from the sports. Two cases used braces after cast fixation. Excluding one case, all of the cases showed good results.
