S82.431K Displaced oblique fracture of shaft of right fibula, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced oblique fracture of shaft of right fibula, subsequent encounter for closed fracture with nonunion

Summary

This condition involves a displaced oblique fracture of the right fibula's shaft, where the bone breaks at an angle and the fragments are misaligned. The "subsequent encounter" indicates this is a follow-up treatment session after the initial injury. The fracture is closed (skin not broken) and has nonunion, meaning the bone has failed to heal properly within the expected timeframe.

Causes

Typically caused by high-impact trauma, such as falls, sports injuries, or motor vehicle accidents. Direct force or twisting injuries to the lower leg can lead to this type of fracture. Nonunion may result from inadequate immobilization, poor blood supply, or infection.

Risk Factors

• Engaging in high-impact sports or physical activities.
• Osteoporosis or other conditions that weaken bones.
• Smoking, which impairs bone healing.
• Previous fractures or bone surgeries.

Symptoms

• Persistent pain in the lower right leg.
• Swelling and bruising around the fracture site.
• Inability to bear weight on the injured leg.
• Visible deformity if the displacement is significant.
• Delayed healing or lack of improvement over time.

Diagnosis

Physical examination to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, to confirm the fracture type, displacement, and nonunion. Additional tests like CT scans or bone scans may be used to evaluate healing progress.

Treatment Options

• Immobilization with a cast or brace to support the fracture.
• Pain management with medications.
• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• Physical therapy to restore strength and mobility.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and treatment response. Follow-up care is essential to monitor healing and adjust treatment as needed. Regular imaging may be required to assess progress.

Complications

• Chronic pain or discomfort.
• Limited mobility or functional impairment.
• Increased risk of future fractures.
• Infection (if surgical intervention is performed).

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking to improve healing outcomes.
• Use protective gear during sports or activities with a risk of leg injury.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact your healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the fracture type (displaced oblique), location (right fibula shaft), encounter type (subsequent), and nonunion status clearly. Ensure the fracture is classified as closed and specify the nonunion to accurately reflect the condition.
