S82.812 Torus fracture of upper end of left fibula

Name of the Condition

• Torus fracture of upper end of left fibula

Summary

A torus fracture of the upper end of the left fibula is an incomplete fracture that occurs in 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 once healing progresses.
• Surgical intervention is rarely needed for uncomplicated torus fractures.

Prognosis and Follow-Up

Most torus fractures heal well with conservative treatment. Follow-up appointments monitor healing and ensure proper recovery. Return to normal activities typically occurs within 4–6 weeks, depending on age and severity.

Complications

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

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Ensure proper footwear and safe play environments for children.
• Strengthen lower leg muscles to improve stability.

When to Seek Professional Help

Seek immediate care if pain is severe, swelling worsens, or weight-bearing is impossible. Also, consult a provider if symptoms do not improve with initial treatment or if deformity is present.

Tips for Medical Coders

Document the specific location (upper end of left fibula) and fracture type (torus) to support accurate coding. Include details on fracture status (e.g., closed) and encounter type (e.g., initial, subsequent) as applicable. Ensure clinical documentation aligns with the ICD-10-CM code S82.812.
