Introduction
Perthes disease is a self-limiting avascular necrosis of the femoral head. It is more common in boys aged 3 to 11 years old however may develop in girls and adolescents. It is usually unilateral but can be bilateral.
For unknown reasons, the blood supply to the femoral head is interrupted causing a cascade of necrosis, reabsorption of damaged bone and rebuilding. The disease process is variable but can take 2 to 4 years from avascular state to full remodelling of the femoral head. The goal of treatment is to maintain the spherical shape of the femoral head through the healing phase to prevent later onset of arthritis
