We retrospectively analyzed cases of intra-articular medial malleolar fractures in skeletally-immature patients (Salter-Harris III and IV) with suboptimal outcomes at St. Louis Children’s Hospital and Shriner’s Hospital for Children. Common causes of poor outcome were fracture malunion or malreduction and physeal damage. Malreductions of only 2 mm does not appear to be tolerated and the concept of “remodeling” does not apply to these fracture patterns. Based on this study, we recommend fracture reduction and fixation if there is greater than 1 mm of fracture step-off.
