S82.422 Displaced transverse fracture of shaft of left fibula

Name of the Condition

• Displaced transverse fracture of shaft of left fibula
• ICD-10 Code: S82.422

Summary

A displaced transverse fracture of the shaft of the left fibula is a break in the long, thin bone on the lateral side of the lower leg, where the bone fragments are separated and misaligned. The fracture line runs horizontally across the middle portion of the bone, and the displacement indicates the fragments are not in their normal anatomical position.

Causes

Most commonly caused by direct trauma or high-impact forces to the leg, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or sudden impacts can 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.
• Visible 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, determine its extent, and evaluate the degree of displacement.

Treatment Options

• Immobilization of the leg with a cast or brace to allow healing.
• Pain management with medications or other therapies.
• Surgical intervention may be required for severe displacement or instability, involving realignment and fixation of the bone fragments.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time varies based on fracture severity and patient factors. Follow-up appointments are necessary to monitor healing, assess alignment, and adjust treatment as needed. Full recovery may take several weeks to months, depending on the injury and rehabilitation.

Complications

• Delayed healing or nonunion of the fracture.
• Malunion, where the bone heals in a misaligned position.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or reduced mobility in the affected leg.

Lifestyle & Prevention

• Use protective gear during high-risk activities like 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 improve stability and reduce injury likelihood.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of nerve or vascular compromise (e.g., numbness, coldness, or discoloration) after a leg injury.

Tips for Medical Coders

Document the specific side (left fibula) and fracture characteristics (displaced, transverse) to ensure accurate coding. Include details on displacement severity and any associated injuries if present. Verify that the fracture is isolated to the shaft of the fibula and not involving the proximal or distal ends, as this affects code specificity.
