What age range most commonly presents with persistent hip pain leading to a diagnosis of Legg-Calve-Perthes disease?

Legg-Calve-Perthes disease is a condition that primarily affects children and is characterized by avascular necrosis of the femoral head. The age range most commonly associated with this condition is between 3 to 12 years old. During this period of development, children are at a higher risk for this disease due to the ongoing growth and changes in the hip joint structure.

The diagnosis often presents with persistent hip pain, limping, or decreased range of motion in the affected hip, which can further be linked to differentiating conditions in younger or older age groups. In those under 3 years, the incidence is significantly lower, and in older adolescents or young adults, the presentation of hip pain typically involves different diagnoses, such as hip impingement or labral tears rather than Legg-Calve-Perthes disease. This understanding of age-related prevalence is crucial in making timely and accurate diagnoses for effective management of potential complications associated with the disease.
