S82.82 Torus fracture of lower end of fibula

Name of the Condition

• Torus fracture of lower end of fibula

Summary

A torus fracture of the lower end of the fibula is an incomplete fracture that occurs in the distal (lower) portion of the fibula, the smaller bone in the lower leg. This injury typically results from a bending force, causing the bone to buckle rather than break completely. It is more common in children due to their softer, more pliable bones.

Causes

Direct trauma or impact to the lower leg, such as a fall or collision. Sudden twisting or bending of the ankle, often seen in sports or physical activities.

Risk Factors

• Participation in high-impact sports or activities that involve sudden movements.
• Age, as children are more susceptible due to developing bone structure.
• Previous injuries or conditions that weaken bone integrity.

Symptoms

• Localized pain and tenderness at the fracture site.
• Swelling and mild bruising around the ankle or lower leg.
• Difficulty bearing weight on the affected leg.
• Possible visible deformity or instability in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and rule out other injuries. Occasionally, additional imaging (e.g., CT or MRI) if the fracture is complex or associated with other injuries.

Treatment Options

Treatment typically involves immobilization with a cast or splint to allow the bone to heal. Pain management may include over-the-counter or prescription medications. Physical therapy may be recommended to restore strength and mobility once healing progresses. In most cases, surgery is not required.

Prognosis and Follow-Up

Prognosis is generally favorable, with most fractures healing within 4-6 weeks. Follow-up appointments may be scheduled to monitor healing and adjust treatment as needed. Children often recover more quickly due to their bone elasticity.

Complications

Rare complications include malunion (improper healing), nonunion (failure to heal), or persistent pain. Infection or nerve damage may occur if the fracture is open or associated with other injuries.

Lifestyle & Prevention

• Use appropriate protective gear during sports or activities.
• Ensure safe play environments to reduce fall risks.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid high-impact activities if bone density is compromised.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or weight-bearing is impossible. Immediate care is needed if the leg appears deformed, numbness or tingling occurs, or there are signs of infection (e.g., fever, redness).

Tips for Medical Coders

Document the specific location (lower end of fibula) and fracture type (torus) to ensure accurate coding. Include details on trauma mechanism, patient age, and imaging results to support the diagnosis. Verify that the fracture is incomplete and confined to the distal fibula, as this distinguishes it from other lower leg fractures.
