INTRODUCTION
Coxa Plana, also known as the Legg-Calve-Perthes Disease is a self limited disorder that is characterized by the deterioration of the head of the femur in the hip joint due to insufficient blood supply. It is an avascular necrosis of the proximal femoral epiphysis from an unknown cause that mostly occurs to children, specifically boys aging 4 to 10 years. The decrease and not enough blood supply in the bones causes the bones to die. As necrosis approach, ball of the hip collapse and become flat thus causing the hip displacement at the same time.
Children with the disease pass through 4 specific stages. The first stage is the synovitis stage or the period of painful inflammation. With this stage patient may experience several painful attacks that may either be in the knees, groin or the hips. Particularly, no two children with the same diagnosis are experiencing the same pain. The second stage is the necrotic stage. In this stage the bone in the femur head becomes smaller and shows increased density on the x-ray. This may lasts for 6-12 months. The third stage is the fragmentation stage where the resorption of dead bone occurs over 1-2 year period. The head of the femur gradually reform as dead bone is replaced with new bone, which gradually spreads to heal the lesion. Reconstruction stage or the final stage is where the final healing with the deposition of new bone occurs. In this post recovery stage the femoral head become permanently distorted, with resultant to joint misalignment.
Out of 1200 children younger than 10 years is affected by the disease in the United States. In the Philippines, the condition is considered rare occurring in an approximately 4 of 100,000 children. This disease
