S82.442 Displaced spiral fracture of shaft of left fibula

Name of the Condition

• Displaced spiral fracture of shaft of left fibula

Summary

A displaced spiral fracture of the left fibula's shaft is a bone break characterized by a helical pattern along the fibular shaft, 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.
• Surgery may be necessary to realign and fix the fracture using metal rods or screws.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and treatment. Most patients recover fully with proper care, but follow-up imaging may be needed to ensure healing. Physical therapy is often recommended to restore strength and mobility.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in an incorrect position.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or stiffness in the lower leg.

Lifestyle & Prevention

• Wear appropriate protective gear during high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid activities that pose a high risk of twisting injuries to the leg.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a leg injury, or if you cannot bear weight on the affected leg.

Tips for Medical Coders

Document the fracture's displacement, location (left fibula), and any associated injuries. Ensure the diagnosis aligns with clinical findings and imaging results. Use this code for initial encounters of closed fractures; specify laterality and displacement accurately.
