S82.443 Displaced spiral fracture of shaft of unspecified fibula

Name of the Condition

• Displaced spiral fracture of shaft of unspecified fibula

Summary

A displaced spiral fracture of the fibular shaft is a bone break characterized by a helical pattern along the shaft of the fibula, with misalignment of the bone fragments. This fracture typically results from twisting forces applied to the leg and may cause significant pain and mobility impairment.

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 the bone to heal.
• Pain management with medications like NSAIDs or opioids.
• Surgical intervention may be required for severe displacement or instability.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time depends on fracture severity and patient factors. Follow-up appointments are necessary to monitor healing, assess alignment, and adjust treatment as needed. Full weight-bearing may be delayed until the fracture is stable.

Complications

• Delayed healing or nonunion of the fracture.
• Malunion, where the bone heals in an incorrect position.
• Nerve or vascular damage in severe cases.
• Chronic pain or stiffness in the lower leg.

Lifestyle & Prevention

• Use proper protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid activities that pose a high risk of twisting injuries.
• Strengthen lower leg muscles to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, or deformity after an injury, or if you cannot bear weight on the affected leg. Persistent pain or difficulty walking after initial treatment also warrants evaluation.

Tips for Medical Coders

When coding S82.443, ensure documentation specifies the fracture as displaced and spiral, involving the shaft of the fibula without specifying laterality. Verify that the injury is not associated with other fractures or complications that may require additional codes. Accurate clinical documentation is essential to support the code assignment.
