S82.819 Torus fracture of upper end of unspecified fibula

Name of the Condition

• Torus fracture of upper end of unspecified fibula

Summary

A torus fracture of the upper end of the unspecified fibula is an incomplete fracture affecting the proximal (upper) portion of the fibula, the smaller bone in the lower leg. This injury 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

• Immobilization with a cast or splint to allow healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore strength and mobility after healing.
• Surgical intervention is rarely needed for uncomplicated cases.

Prognosis and Follow-Up

Most torus fractures heal well with conservative treatment. Follow-up appointments monitor healing progress, typically with repeat imaging if symptoms persist. Full recovery is expected within 4–6 weeks for children, with gradual return to normal activities as tolerated.

Complications

• Delayed healing or nonunion in rare cases.
• Persistent pain or stiffness.
• Associated injuries to ligaments or other bones in the lower leg.

Lifestyle & Prevention

• Use appropriate protective gear during sports or high-risk activities.
• Ensure safe play environments to reduce fall risks.
• Maintain bone health through adequate nutrition and exercise.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or weight-bearing becomes impossible. Immediate care is needed for severe deformity, open wounds, or signs of infection.

Tips for Medical Coders

Document the unspecified nature of the fibula (left/right) if clinical details are unavailable. Ensure the fracture is confirmed as torus (incomplete buckling) rather than a complete break. Include any associated injuries or treatment details to support code specificity.
