Abstract

Abstract : Case: Cortical atrophy, or stress shielding, secondary to a large-diameter femoral intramedullary rod was noted over almost a decade in a now 14-year-old girl with osteogenesis imperfecta (OI). After an initial minimally invasive unsuccessful revision, we downsized the left femur rod with realignment and noted restoration of the left femur cortical thickness. Conclusion: We demonstrate the significant functional impact of stress shielding and its evolution over a protracted period and outline treatment principles. To our knowledge, this is the first report of treatment of stress shielding of a long bone in the setting of OI.
