S82.443G Displaced spiral fracture of shaft of unspecified fibula, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Displaced spiral fracture of shaft of unspecified fibula, subsequent encounter for closed fracture with delayed healing

Summary

A displaced spiral fracture of the fibular shaft involves a helical break with misaligned bone fragments, classified as a closed fracture (no skin break) during a subsequent encounter where healing is delayed. This fracture typically results from twisting forces and may cause persistent pain, swelling, or mobility issues due to prolonged healing.

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

• Persistent 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.
• Delayed healing signs (e.g., lack of visible bone union on imaging).

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, with follow-up imaging to evaluate healing progress. Additional imaging, such as CT or MRI, may be ordered for complex cases or to evaluate soft tissue damage.

Treatment Options

• Immobilization (e.g., cast or brace) to support healing.
• Pain management (e.g., NSAIDs, analgesics).
• Physical therapy to restore mobility and strength.
• Surgical intervention (e.g., fixation) if healing does not progress.

Prognosis and Follow-Up

Prognosis depends on fracture severity, patient health, and adherence to treatment. Follow-up imaging and clinical assessments monitor healing. Delayed healing may require extended immobilization or additional interventions.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or instability.
• Nerve or vascular damage (rare).
• Infection (if surgical intervention is needed).

Lifestyle & Prevention

• Avoid high-impact or rotational activities until cleared by a provider.
• Maintain bone health through diet (calcium, vitamin D) and exercise.
• Use protective gear during sports or high-risk activities.
• Follow rehabilitation guidelines to support healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility does not improve. Contact a provider if signs of infection (e.g., fever, redness) or new deformity appear.

Tips for Medical Coders

Document the fracture type (displaced spiral), bone (unspecified fibula), encounter type (subsequent), and healing status (delayed healing). Include clinical notes confirming closed fracture and delayed healing to support code assignment.
