Early-onset blount's disease in a two-year-old child

Blount's disease is an acquired growth disorder involving the medial aspect of the proximal tibial physis, epiphysis, and metaphysis. Infantile Blount's disease, one of its variants, commonly presents with progressive lower limb bowing and limb length discrepancy. Because physiological bowing and nutritional rickets are far more common in this age group, early-onset Blount's disease is frequently overlooked in primary care settings. Early diagnosis is crucial, as timely intervention can halt disease progression, prevent worsening deformity, and reduce the need for surgical correction, whereas delayed recognition may lead to irreversible growth disturbances. This case is noteworthy because it highlights the importance of early clinical suspicion and radiological evaluation of pathological bowing in a toddler presenting first to a family medicine clinic. We report the case of a two years old girl with bilateral lower limb bowing, normal biochemical findings, and radiological features like bilateral medial tibial metaphyseal beaking (spur formation) with genu varum deformity and preserved bone density, findings consistent with early-onset Blount's disease.
