In simple words: Legg-Calvé-Perthes disease is a hip problem that mostly affects children between 4 and 12 years old.Part of the hip bone temporarily loses its blood supply, causing it to soften and potentially change shape. While the bone usually heals itself, the new bone might not be perfectly round, which can cause hip problems later in life.

Pseudocoxalgia, or Legg-Calvé-Perthes disease, is a childhood condition affecting the hip joint.It involves disruption of blood supply to the femoral head, leading to avascular necrosis (bone tissue death). This weakens the femoral head, making it susceptible to deformation from weight-bearing and movement. Over time, the blood supply typically returns, and new bone grows, but the shape of the femoral head may be altered. This can lead to pain, stiffness, and limited range of motion in the hip.

Example 1: A 7-year-old boy presents with a limp and intermittent hip pain, especially after activity. X-rays reveal flattening of the femoral head, consistent with early-stage Legg-Calvé-Perthes disease., A 9-year-old girl experiences worsening hip pain and limited range of motion. Imaging shows fragmentation of the femoral head, indicating a more advanced stage of pseudocoxalgia., A 5-year-old boy completes a course of conservative treatment for Perthes disease, including bracing and physical therapy. Follow-up X-rays show new bone growth and improved femoral head shape.

Documentation should include details of the patient's symptoms (e.g., pain, limp, limited range of motion), physical examination findings, and imaging results. The stage of the disease and any treatment provided should also be documented.
