M92.71 Juvenile osteochondrosis of metatarsus, right foot

Name of the Condition

• Juvenile osteochondrosis of metatarsus, right foot

Summary

Juvenile osteochondrosis of the metatarsus, right foot, is a growth-related disorder affecting the metatarsal bones in the right foot of children and adolescents. It involves disrupted blood flow to the growth plates, leading to bone and cartilage changes. This condition typically causes pain and functional limitations in the right foot.

Causes

The exact cause is not fully understood, but it is associated with repetitive stress or trauma to the metatarsals during growth spurts. Mechanical stress from activities involving the right foot may contribute to the development of this disorder.

Risk Factors

• Age: Primarily affects children and adolescents during growth periods.
• Physical activity: Participation in sports or activities with repetitive right foot use.
• Gender: More common in males.
• Rapid growth phases during puberty.

Symptoms

• Pain in the right forefoot, especially with weight-bearing.
• Tenderness or swelling over the right metatarsals.
• Reduced range of motion in the right foot.
• Difficulty with activities requiring right foot strength.

Diagnosis

Diagnosis involves a clinical evaluation of symptoms and activity history. Imaging tests, such as X-rays or MRI, may be used to assess bone and cartilage changes in the right metatarsals.

Treatment Options

• Rest and activity modification to reduce stress on the right foot.
• Physical therapy to strengthen surrounding muscles and improve flexibility.
• NSAIDs for pain and inflammation.
• Orthotic devices or supportive footwear to alleviate pressure.
• In severe cases, casting or bracing may be recommended.

Prognosis and Follow-Up

Most cases resolve with conservative treatment as the child matures. Follow-up care focuses on monitoring symptoms, adjusting activity levels, and ensuring proper healing. Long-term outcomes are generally favorable with appropriate management.

Complications

• Persistent pain or functional limitations if untreated.
• Altered gait or foot mechanics.
• Rarely, permanent structural changes to the metatarsals.

Lifestyle & Prevention

• Avoid high-impact activities that stress the right foot.
• Use supportive footwear during sports or daily activities.
• Maintain a healthy weight to reduce foot stress.
• Gradually increase physical activity to prevent overuse.

When to Seek Professional Help

Seek medical attention if pain worsens, limits mobility, or persists despite rest. Consult a healthcare provider for persistent swelling, redness, or difficulty bearing weight on the right foot.

Tips for Medical Coders

Document the laterality (right foot) and specify the metatarsus involvement. Ensure clinical notes support the diagnosis and align with the ICD-10-CM code M92.71. Include details on symptom onset, activity history, and imaging results when available.
