S82.829 Torus fracture of lower end of unspecified fibula

Name of the Condition

• Torus fracture of lower end of unspecified fibula

Summary

A torus fracture of the lower end of the unspecified fibula is an incomplete fracture affecting the distal (lower) portion of the fibula, the smaller bone in the lower leg. This injury occurs when a bending force causes 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. Follow-up care ensures proper healing and restoration of function.

Prognosis and Follow-Up

Prognosis is generally good, with most fractures healing within 4–6 weeks. Follow-up appointments monitor healing progress and may include repeat imaging. Physical therapy may be recommended to restore strength and mobility.

Complications

Rare complications include malunion (improper healing) or nonunion (failure to heal). Infection or nerve damage may occur if the fracture is open or associated with severe trauma.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use protective gear during sports. Maintain bone health through adequate nutrition (e.g., calcium, vitamin D) and regular exercise.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the side (unspecified) and location (lower end of fibula) clearly. Ensure the fracture type (torus) and bone (fibula) are specified. Include details on trauma mechanism or associated injuries if relevant for accurate coding.
