MacFarland fracture is a joint fracture of the ankle in children involving the medial malleolus (Salter-Harris type III or IV). These fractures are acknowledged to have poor prognosis because of the risk of misalignment due to the development of an epiphysiodesis bridge. Current recommended treatment for a displacement of ≥ 2 mm is open reduction through an arthrotomy with screw fixation. This study aimed to evaluate functional and radiologic results of a less-invasive surgical technique consisting of closed reduction, arthrographic control of fracture reposition, and percutaneous screw fixation.
