What is the primary treatment aim for Legg-Calve-Perthes disease?

The primary treatment aim for Legg-Calve-Perthes disease is to maintain range of motion. This is crucial because the condition involves avascular necrosis of the femoral head, leading to pain and limited mobility in the hip joint. Preserving the range of motion helps to reduce stiffness and improve function, which is essential for the overall development and mobility of the affected child.

The approach typically includes non-weight bearing or reduced weight-bearing activities to alleviate stress on the hip joint, alongside physical therapy aimed at maintaining as much range of motion as possible through gentle mobilization and stretching exercises. These strategies can help to maximize the chances of a successful recovery and prevent complications like secondary osteoarthritis or hip deformity in later years.

In contrast, while avoiding sports may seem relevant given the need for cautious activity, the active maintenance of motion is prioritized. Reconstructive surgery is not the first line of treatment unless conservative measures fail and significant deformity occurs.
