S82.461B Displaced segmental fracture of shaft of right fibula, initial encounter for open fracture type I or II

Name of the Condition

• Displaced segmental fracture of shaft of right fibula, initial encounter for open fracture type I or II
• ICD-10 Code: S82.461B

Summary

A displaced segmental fracture of the shaft of the right fibula is a break in the long, thin bone on the lateral side of the lower leg, where the bone is broken into two or more separate pieces and the fragments are out of alignment. This injury involves the middle portion of the fibula and is classified as an open fracture (type I or II), meaning the skin is pierced or there is a wound communicating with the fracture site. The "initial encounter" indicates this is the first time the patient is receiving treatment for this specific injury.

Causes

Most commonly caused by direct trauma or high-impact events, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or forceful impacts to the leg can also lead to this type of fracture. Open fractures may result from the same mechanisms, with additional skin penetration from the injury force or bone fragments.

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.
• Activities with a high risk of falls or direct trauma to the leg.

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.
• Visible wound or skin break at the fracture site (for open fractures).

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, deformity, and the presence of an open wound. Imaging tests, such as X-rays, are typically used to confirm the fracture, determine its extent, alignment, and whether it is open. Additional imaging (e.g., CT scans) may be used to evaluate complex fractures.

Treatment Options

• Immediate wound care and cleaning to reduce infection risk for open fractures.
• Immobilization of the leg using a splint or cast to stabilize the fracture.
• Surgical intervention may be required to realign and fix the bone fragments, especially for displaced or open fractures.
• Pain management with medications such as analgesics.
• Antibiotics may be prescribed for open fractures to prevent infection.
• Physical therapy to restore movement and strength after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the patient’s overall health. Most fractures heal with proper care, but recovery may take several weeks to months. Follow-up appointments are necessary to monitor healing, assess for complications, and adjust treatment (e.g., cast removal, physical therapy progression).

Complications

• Infection, particularly with open fractures.
• Delayed healing or nonunion of the fracture.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or instability in the leg.
• Post-traumatic arthritis in the ankle or knee.

Lifestyle & Prevention

• Wear appropriate protective gear during high-impact activities or sports.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid activities with a high risk of falls or leg trauma when possible.
• Use caution on uneven surfaces to reduce fall risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, deformity, or an open wound after an injury. Prompt care is essential for open fractures to reduce infection risk and ensure proper healing.

Tips for Medical Coders

Document the fracture type (displaced segmental), location (shaft of right fibula), and encounter type (initial) clearly. For open fractures, specify the type (I or II) based on wound size and contamination. Ensure documentation supports the "open" classification to justify the code.
