S82.49 Other fracture of shaft of fibula

Name of the Condition

• Other fracture of shaft of fibula
• ICD-10 Code: S82.49

Summary

This condition refers to a fracture (break) of the shaft of the fibula, the smaller bone in the lower leg, that does not fall into more specific categories (e.g., transverse, spiral, or unspecified). The term "other" indicates the fracture type is distinct but not classified under narrower subcategories. The injury may involve the middle portion of the fibula and can vary in severity, such as displaced or non-displaced, open or closed.

Causes

Most commonly caused by direct trauma or impact to the leg, such as from falls, sports injuries, or motor vehicle accidents. High-force impacts, twisting motions, or repetitive stress may also lead to this type of fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries.

Symptoms

• Pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine its extent and alignment.

Treatment Options

• Immobilization of the leg using a splint or cast to allow the bone to heal properly.
• Pain management with medications such as analgesics.
• Physical therapy to restore movement and strength.
• Surgical intervention may be required for severe or displaced fractures.

Prognosis and Follow-Up

Prognosis depends on the fracture severity, alignment, and treatment adherence. Most fractures heal within 6–8 weeks with proper immobilization. Follow-up appointments monitor healing progress, and physical therapy may be recommended to restore function. Complications like nonunion or malunion are rare but possible with severe injuries.

Complications

• Nonunion (failure of the bone to heal).
• Malunion (improper healing leading to deformity).
• Nerve or blood vessel damage.
• Chronic pain or instability.

Lifestyle & Prevention

• Wear protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid activities that increase fall risk, especially in older adults.
• Strengthen leg muscles to support the fibula and improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness, drainage) after an injury.

Tips for Medical Coders

Document the fracture type (e.g., oblique, comminuted) and any associated injuries (e.g., soft tissue damage) to support the S82.49 code. Ensure the medical record specifies the fracture is of the fibula shaft and not another bone or location. Use additional codes for complications or comorbidities as needed.
