Name of the Condition

• Coxa Plana, Right Hip
• Also known as Legg-Calvé-Perthes disease affecting the right hip.

Summary

Coxa plana refers to the flattening of the femoral head in the hip joint, typically due to a temporary loss of blood supply. It's most common in children and can lead to hip pain and limping.

Causes

• The exact cause is unclear, but it's believed to result from disrupted blood flow to the femoral head.
• May be related to genetic factors, trauma, or inflammation.

Risk Factors

• Age: Most commonly affects children between 4 and 10 years old.
• Gender: More prevalent in boys than girls.
• Family History: Genetics may play a role.
• Exposure to secondhand smoke: Some studies suggest an association.

Symptoms

• Limping or difficulty walking.
• Hip or groin pain that may extend to the thigh or knee.
• Stiffness and reduced range of motion in the hip.

Diagnosis

• Physical Examination: Assessing hip movement and pain levels.
• Imaging: X-rays and MRI scans to observe changes in the femoral head.

Treatment Options

• Rest and Activity Modification: Reducing weight-bearing activities to prevent further damage.
• Physical Therapy: To maintain hip range of motion.
• Medications: Pain relief medications such as NSAIDs.
• Surgery: In severe cases, procedures like osteotomy to reshape the femoral head may be required.

Prognosis and Follow-Up

• The outcome varies; with early treatment, many children recover with normal hip function.
• Regular follow-up is crucial to monitor hip development.

Complications

• Without treatment, it can lead to permanent deformity or arthritis in adulthood.

Lifestyle & Prevention

• Encouraging low-impact activities.
• Monitoring for early signs if there's a family history.

When to Seek Professional Help

• Persistent hip or knee pain in children.
• Noticeable limping or changes in gait.

• Perthes Association (perthes.org.uk): Offers information and support for patients and families.
• American Academy of Orthopaedic Surgeons (orthoinfo.aaos.org): Provides educational materials on hip disorders.

Tips for Medical Coders

• Ensure correct laterality (right hip) when coding.
• Verify patient age as this condition is primarily pediatric.
• Double-check for presence of bilateral conditions for additional coding.
