S82.453 Displaced comminuted fracture of shaft of unspecified fibula

Name of the Condition

• Displaced comminuted fracture of shaft of unspecified fibula
• ICD-10 Code: S82.453

Summary

A displaced comminuted fracture of the shaft of the unspecified fibula is a break in the long, slender bone of the lower leg where the bone is shattered into multiple pieces and the fragments are no longer aligned. This type of fracture involves the middle portion of the fibula and may result from significant trauma. The term "unspecified" indicates the side (left or right) is not documented.

Causes

This fracture is typically caused by direct trauma to the leg, such as a high-impact fall, motor vehicle accident, or sports injury, which forces the bone to break into several fragments and shift out of position. Twisting motions or repetitive stress can also contribute to this type of injury.

Risk Factors

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

Symptoms

• Severe pain and tenderness along the fibula
• Swelling, bruising, or deformity of the lower leg
• Inability to bear weight on the affected leg
• Possible instability or abnormal movement of the leg

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, followed by imaging tests such as X-rays to confirm the fracture type, displacement, and comminution. Additional imaging like CT scans may be used for complex cases to evaluate fragment alignment and associated injuries.

Treatment Options

Treatment depends on the severity of the fracture, including fragment displacement and bone stability. Options may include immobilization with a cast or brace, surgical intervention to realign and fix fragments with hardware, or physical therapy to restore function and strength. Pain management and activity modification are also part of the care plan.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and patient factors like age and overall health. Most patients recover with proper care, though healing may take several months. Follow-up appointments monitor healing progress, adjust treatment as needed, and assess for complications. Physical therapy is often recommended to regain mobility and strength.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), infection (especially if open fracture), nerve or blood vessel damage, chronic pain, or arthritis in the affected area. Early intervention and adherence to treatment plans reduce these risks.

Lifestyle & Prevention

• Use protective gear during high-impact activities or sports.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive stress on the legs and practice proper body mechanics.
• Seek prompt medical care for leg injuries to prevent further damage.

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, deformity, or inability to bear weight after an injury. Also, consult a healthcare provider if symptoms worsen or do not improve with initial care, or if you notice signs of infection (e.g., fever, increased redness, or drainage).

Tips for Medical Coders

Document the fracture as "displaced comminuted" and specify the shaft of the fibula. Use S82.453 when the side (left or right) is not documented. Ensure clinical documentation supports the displacement and comminution to justify the code. Verify that no other specific codes (e.g., for open fractures or associated injuries) are applicable before assigning this code.
