S82.423 Displaced transverse fracture of shaft of unspecified fibula

Name of the Condition

• Displaced transverse fracture of shaft of unspecified fibula
• ICD-10 Code: S82.423

Summary

A displaced transverse fracture of the shaft of the unspecified 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. This injury may result from significant force, leading to misalignment of the bone fragments.

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 if the fracture is severely displaced or unstable.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, treatment, and individual factors. Most fractures heal with proper care, but follow-up appointments are necessary to monitor healing and adjust treatment as needed. Recovery may take several weeks to months, with gradual return to normal activities.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in an incorrect position.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or stiffness in the leg.

Lifestyle & Prevention

• Wear appropriate protective gear during sports or high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid activities that increase the risk of falls or leg injuries.
• Use caution on uneven surfaces or in hazardous environments.

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., fever, increased swelling, redness) after an injury.

Tips for Medical Coders

When coding S82.423, ensure the documentation specifies a displaced transverse fracture of the fibula shaft without indicating laterality (right or left). Verify that the fracture is transverse (horizontal) and not another type (e.g., oblique or spiral). Confirm the displacement is clearly documented, as this distinguishes it from non-displaced fractures. Accurate clinical details are essential for correct code assignment.
