S82.451C Displaced comminuted fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Displaced comminuted fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC
• ICD-10 Code: S82.451C

Summary

A displaced comminuted fracture of the shaft of the right 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 fracture is classified as an open (compound) fracture, meaning the bone has pierced the skin, and is categorized as type IIIA, IIIB, or IIIC based on the severity of soft tissue damage and contamination. The initial encounter indicates this is the first time the fracture is being treated.

Causes

This fracture typically results from high-impact trauma to the leg, such as motor vehicle accidents, falls from significant heights, or severe sports injuries. The force of the trauma causes the bone to break into multiple fragments and displace, while also creating an open wound that exposes the fracture site.

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
• Activities involving high-speed or forceful impacts

Symptoms

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

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, deformity, and the presence of an open wound. Imaging tests such as X-rays are used to confirm the fracture type, displacement, and comminution. Additional imaging like CT scans may be used for complex cases to evaluate soft tissue damage and fracture details.

Treatment Options

• Surgical intervention to clean the wound, realign bone fragments, and stabilize the fracture (e.g., internal fixation with plates or screws)
• Antibiotics to prevent infection due to the open wound
• Pain management with medications
• Wound care to promote healing and reduce infection risk
• Immobilization with a cast or brace post-surgery
• Physical therapy to restore mobility and strength after healing

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and treatment response. Recovery may take several months, with follow-up appointments to monitor healing, remove hardware if used, and assess functional recovery. Physical therapy is often necessary to regain full leg function.

Complications

• Infection at the open wound site
• Delayed healing or nonunion of the fracture
• Nerve or blood vessel damage
• Chronic pain or instability
• Post-traumatic arthritis

Lifestyle & Prevention

• Use 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 trauma
• Strengthen leg muscles to improve stability and reduce injury 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 treatment is critical to prevent complications and ensure proper healing.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm the initial encounter status. Note the presence of an open wound and any associated soft tissue damage. Ensure the right fibula and shaft location are clearly documented to support accurate coding.
