M91.11 Juvenile osteochondrosis of head of femur [Legg-Calve-Perthes], right leg

Name of the Condition

• Juvenile Osteochondrosis of Head of Femur [Legg-Calve-Perthes], Right Leg

Summary

Juvenile osteochondrosis of the head of the femur, also known as Legg-Calvé-Perthes disease, is a condition affecting the growing femoral head in children. It involves temporary loss of blood supply, leading to bone fragmentation and potential deformity. The right leg is specifically affected in this case.

Causes

The exact cause is not fully understood, but it is thought to result from disrupted blood flow to the femoral head. Mechanical stress, genetic predisposition, and developmental factors may contribute to the onset of the condition.

Risk Factors

• Age: Most commonly affects children between 4 and 10 years old.
• Gender: More prevalent in males.
• Genetic factors: Family history may increase risk.
• Mechanical stress: Repetitive or excessive load on the hip.

Symptoms

• Hip or groin pain, often worsened by activity.
• Limping or altered gait.
• Reduced range of motion in the hip.
• Pain that may radiate to the thigh or knee.
• Stiffness in the affected hip.

Diagnosis

Diagnosis involves a physical examination to assess hip mobility and pain, followed by imaging studies such as X-rays, MRI, or CT scans to evaluate bone and joint structures. Clinical history and symptom patterns are also considered.

Treatment Options

• Rest and Activity Modification: Reducing high-impact activities to prevent further damage.
• Physical Therapy: To maintain hip range of motion and strength.
• Medications: Pain relief medications such as NSAIDs.
• Bracing or Casting: To support the hip during healing.
• Surgery: In severe cases, procedures like osteotomy or femoral osteotomy may be performed to reshape the femoral head.

Prognosis and Follow-Up

Prognosis depends on the severity of the condition and the age of onset. Early diagnosis and appropriate treatment can improve outcomes. Follow-up care typically involves regular monitoring of hip development and function, with imaging studies as needed.

Complications

• Hip deformity: Potential long-term changes in femoral head shape.
• Arthritis: Increased risk of osteoarthritis in adulthood.
• Limited mobility: Persistent stiffness or reduced range of motion.
• Limping: Chronic gait abnormalities.

Lifestyle & Prevention

• Avoid high-impact activities: Reduce stress on the hip joint.
• Maintain a healthy weight: Minimize load on the affected leg.
• Follow treatment plans: Adhere to prescribed rest and therapy.
• Regular monitoring: Attend follow-up appointments to track progress.

When to Seek Professional Help

Seek medical attention if your child experiences persistent hip pain, limping, or reduced mobility. Early evaluation can help prevent complications and guide appropriate treatment.

Tips for Medical Coders

Document the specific laterality (right leg) and confirm the diagnosis aligns with juvenile osteochondrosis of the femoral head. Ensure clinical documentation supports the use of this code and includes details about the affected side and any associated symptoms or treatments.
