Legg-Calvé-Perthes Disease

Area of Science:

• Pediatric Orthopedics
• Avascular Necrosis Research

Background:

• Legg-Calve-Perthes disease (LCPD) is idiopathic avascular necrosis of the hip in children.
• It presents a spectrum of pathology from mild to severe, potentially causing permanent hip joint degeneration.

Observation:

• Pediatric hip pathology may manifest as knee or thigh pain, necessitating hip awareness during examination.
• Key findings include limited hip abduction/rotation and Trendelenburg gait.
• Radiographs show anterolateral femoral head changes, sometimes subtle on early frog lateral views.

Findings:

• LCPD involves insidious onset of hip avascular necrosis in the pediatric population.
• Radiographic evidence is crucial for diagnosis, especially early subtle changes.
• Clinical presentation can be non-specific, with referred pain to the knee or thigh.

Implications:

• Treatment focuses on restoring hip range of motion and ensuring femoral head coverage.
• Surgical interventions aim to reorient the femoral head or pelvis for optimal coverage.
• Effective management is vital to prevent long-term degenerative changes in the pediatric hip.
