S82.65 Nondisplaced fracture of lateral malleolus of left fibula

Name of the Condition

• Nondisplaced fracture of lateral malleolus of left fibula

Summary

A nondisplaced fracture of the lateral malleolus of the left fibula is a break in the outer bony prominence of the left ankle (part of the fibula) where the bone fragment remains in its normal anatomical position. This injury typically results from trauma and may involve minimal disruption to the ankle joint's stability.

Causes

Direct trauma to the ankle, such as a fall or impact. Twisting or rolling of the ankle during activities. High-impact injuries, including sports or accidents.

Risk Factors

• Participation in activities with high ankle stress (e.g., running, jumping).
• Osteoporosis or weakened bone density.
• Previous ankle injuries that may compromise stability.
• Age-related bone fragility.

Symptoms

• Pain localized to the outer left ankle.
• Swelling and bruising around the fracture site.
• Difficulty bearing weight or walking.
• Minimal to no visible deformity.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate its alignment. Additional scans (e.g., CT or MRI) may be ordered for detailed assessment if needed.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Pain management through medications or ice therapy.
• Non-surgical management for stable, nondisplaced fractures.
• Surgical intervention if instability or displacement is detected later.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments monitor healing progress, typically with repeat imaging. Full recovery may take several weeks to months, depending on the individual's health and adherence to treatment.

Complications

• Delayed healing or nonunion.
• Post-traumatic arthritis.
• Nerve or soft tissue damage.
• Increased risk of future ankle instability.

Lifestyle & Prevention

• Wear supportive footwear during activities.
• Strengthen ankle muscles through targeted exercises.
• Avoid high-risk movements or surfaces that increase fall risk.
• Maintain bone health with adequate nutrition and exercise.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or weight-bearing becomes impossible. Contact a healthcare provider if symptoms persist beyond initial treatment or if new deformity or numbness develops.

Tips for Medical Coders

Document the laterality (left fibula) and confirm the fracture is nondisplaced. Include details on imaging results, treatment provided, and any follow-up care. Ensure the code aligns with clinical documentation to reflect the specific anatomical location and fracture characteristics.
