S82.811 Torus fracture of upper end of right fibula

Name of the Condition

• Torus fracture of upper end of right fibula
• ICD-10 Code: S82.811

Summary

This condition refers to a torus fracture, a type of incomplete fracture, specifically affecting the upper end of the right fibula. Torus fractures involve buckling of the bone cortex without complete disruption, commonly seen in children due to their softer, more pliable bones. The upper end of the fibula is the proximal portion near the knee joint.

Causes

Torus fractures typically result from low-energy trauma, such as falls onto an outstretched hand or direct impact to the leg. The mechanism often involves axial loading or bending forces that cause the bone to buckle rather than break completely.

Risk Factors

• Participation in activities with a risk of falls or minor impacts.
• Pediatric age group, as bone elasticity is higher.
• Sports or play involving running, jumping, or contact.
• Previous history of fractures or bone disorders affecting bone strength.

Symptoms

• Localized pain and tenderness at the fracture site.
• Mild swelling or bruising around the upper fibula.
• Limited range of motion in the knee or ankle.
• Possible deformity or prominence at the fracture area.

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and potential deformity. Imaging tests, such as X-rays, are used to confirm the fracture type and location. CT scans or MRIs may be employed for detailed visualization if the fracture is complex or associated with other injuries.

Treatment Options

• Immobilization: A cast or brace to stabilize the fracture and allow healing.
• Pain management: Over-the-counter or prescription medications to reduce discomfort.
• Activity modification: Limiting weight-bearing or high-impact activities during recovery.
• Follow-up imaging: To monitor healing progress and ensure proper alignment.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, as torus fractures typically heal without complications. Follow-up visits are recommended to assess healing and adjust immobilization as needed. Most patients regain full function within a few weeks to months, depending on age and fracture severity.

Complications

• Delayed healing or nonunion, though rare.
• Residual pain or stiffness in the affected area.
• Risk of re-injury if activity is resumed too quickly.
• Potential for associated ligament or soft tissue damage.

Lifestyle & Prevention

• Wear protective gear during sports or high-risk activities.
• Ensure proper footwear and safe play environments for children.
• Maintain bone health through adequate nutrition and exercise.
• Gradually return to activity after injury to avoid re-injury.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility is severely limited. Immediate care is needed if there is visible deformity, inability to bear weight, or signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the specific location (upper end of right fibula) and fracture type (torus) to ensure accurate coding. Include details about the encounter type (e.g., initial, subsequent) and whether the fracture is open or closed, as these affect code assignment. Verify laterality (right) and anatomical specificity to align with ICD-10-CM guidelines.
