There is no cure for Legg-Calve-Perthes disease, but there are medications and treatments that can help manage the symptoms. Non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. Physical therapy can help improve range of motion and strength. Surgery may be necessary in some cases to correct deformities or to stabilize the hip joint.

1. Male gender
2. Age (typically between 4-8 years old)
3. Family history of the disease
4. Low birth weight
5. Premature birth
6. Abnormal hip development
7. Obesity
8. Prolonged periods of inactivity
9. Trauma to the hip area

1. Non-surgical treatments:
- Physical therapy: To help maintain range of motion and muscle strength.
- Bracing: To help keep the hip joint in the correct position.
- Activity modification: To reduce stress on the hip joint.

2. Surgical treatments:
- Osteotomy: To realign the hip joint and reduce pressure on the femoral head.
- Femoral head ostectomy: To remove the femoral head and replace it with a prosthetic.
- Femoral head replacement: To replace the femoral head with a prosthetic.

The exact cause of Legg-Calve-Perthes disease is unknown. However, it is believed to be caused by a combination of factors, including genetics, trauma, and decreased blood supply to the hip joint. Other possible causes include infection, metabolic disorders, and abnormal development of the hip joint.

The main symptom of Legg-Calve-Perthes disease is hip pain. Other symptoms may include:

- Limping

- Decreased range of motion in the hip

- Leg muscle wasting

- Leg length discrepancy

- Abnormal gait

- Joint stiffness

- Pain in the groin, thigh, or knee

- Difficulty walking or running

- Difficulty standing up from a sitting position

- Difficulty climbing stairs

- Limb weakness

- Loss of balance or coordination

Legg-Calve-Perthes disease is a rare childhood hip disorder that affects the ball (femoral head) of the hip joint. It is caused by a temporary interruption of the blood supply to the femoral head, resulting in the death of the bone cells and the eventual collapse of the femoral head. Symptoms of Legg-Calve-Perthes disease include pain, limping, and decreased range of motion in the hip joint. Treatment typically involves physical therapy, bracing, and in some cases, surgery.
