S82.44 Spiral fracture of shaft of fibula

Name of the Condition

• Spiral fracture of shaft of fibula

Summary

A spiral fracture of the fibular shaft is a type of bone break characterized by a helical pattern along the shaft of the fibula, the smaller bone in the lower leg. This fracture typically results from twisting forces applied to the leg and may vary in severity, including displacement or non-displacement of the bone fragments.

Causes

Most commonly caused by twisting injuries to the lower leg, such as those sustained during sports, falls, or accidents. High-impact trauma, including direct blows or rotational forces, can also lead to this type of fracture.

Risk Factors

• Participation in activities with high rotational stress (e.g., skiing, gymnastics).
• Osteoporosis or reduced bone density.
• Previous lower leg injuries or fractures.
• Advanced age, which may weaken bone strength.

Symptoms

• Severe pain and swelling in the lower leg.
• Bruising and tenderness at the fracture site.
• Inability to bear weight on the affected leg.
• Possible deformity or instability of the leg.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. X-rays are typically used to confirm the fracture and its spiral pattern. Additional imaging, such as CT or MRI, may be ordered for complex cases or to evaluate soft tissue damage.

Treatment Options

• Immobilization with a cast or splint to allow healing.
• Pain management with medications like NSAIDs.
• Surgery may be required to realign and stabilize the fracture, especially if displaced.

Prognosis and Follow-Up

Most spiral fractures of the fibular shaft heal well with appropriate treatment. Recovery time depends on fracture severity and treatment. Follow-up appointments monitor healing and may include physical therapy to restore strength and mobility.

Complications

• Delayed healing or nonunion.
• Malunion (improper healing).
• Nerve or blood vessel damage.
• Chronic pain or instability.

Lifestyle & Prevention

• Wear protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid twisting injuries by using proper techniques in sports or daily activities.

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, or inability to bear weight after an injury. Prompt evaluation is important to prevent complications.

Tips for Medical Coders

Document the fracture pattern (spiral) and shaft location clearly. Include details on displacement, open/closed status, and treatment provided. Ensure documentation supports the specificity of the code S82.44.
