Paediatric Lower Limb
A 2-year-old girl of African descent presents with progressive bowing of both legs. She started walking at 10 months of age and is noted to be overweight. Her parents are concerned that the bowing is worsening rather than improving. Examination reveals bilateral genu varum that is more pronounced on standing, with internal tibial torsion. Standing AP radiographs show medial metaphyseal beaking of the proximal tibia with fragmentation. The metaphyseal-diaphyseal angle (MDA) measures 18 degrees bilaterally. The orthopaedic surgeon discusses the distinction from physiologic genu varum and the treatment options. Regarding Blount disease (tibia vara) and its management:
