S82.45 Comminuted fracture of shaft of fibula

Name of the Condition

• Comminuted fracture of shaft of fibula
• ICD-10 Code: S82.45

Summary

A comminuted fracture of the shaft of the fibula is a break in the long, slender bone of the lower leg where the bone is shattered into multiple pieces. This type of fracture involves the middle portion of the fibula and may vary in severity depending on factors such as displacement, open or closed status, and associated injuries.

Causes

This fracture is typically caused by direct trauma or high-impact force to the leg, such as from falls, motor vehicle accidents, or sports injuries. Twisting motions or repetitive stress can also lead to comminuted fractures in some cases.

Risk Factors

• Participation in high-impact sports or activities
• Osteoporosis or conditions that weaken bone density
• Advanced age, which may reduce bone strength
• Previous leg injuries or surgeries

Symptoms

• Pain and tenderness along the fibula
• Swelling and bruising around the lower leg
• Difficulty bearing weight on the affected leg
• Possible deformity or instability of the leg structure

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine the number of bone fragments, alignment, and whether the fracture is open or closed.

Treatment Options

• Immobilization using a cast or brace to maintain bone alignment
• Pain management with medications
• Physical therapy to restore mobility and strength after immobilization
• Surgery may be required for severe cases involving displacement or open fractures

Prognosis and Follow-Up

Recovery depends on the severity of the fracture and treatment approach. Most patients heal within 6–8 weeks with proper immobilization and rehabilitation. Follow-up appointments are necessary to monitor healing and adjust treatment as needed.

Complications

• Nonunion or delayed healing of the fracture
• Malunion, where the bone heals in an improper position
• Nerve or blood vessel damage near the fracture site
• Infection (if the fracture is open)

Lifestyle & Prevention

• Use protective gear during high-impact activities
• Maintain bone health through diet and exercise
• Avoid activities that increase fracture risk if you have weakened bones
• Practice safe movement techniques to reduce fall risk

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., redness, pus, fever) after a leg injury.

Tips for Medical Coders

When coding S82.45, ensure documentation specifies the fracture as comminuted and involves the shaft of the fibula. Note whether the fracture is open or closed, as this may impact coding specificity. Include details about treatment approaches and any associated complications to support accurate code assignment.
