S82.821 Torus fracture of lower end of right fibula

Name of the Condition

• Torus fracture of lower end of right fibula

Summary

This condition refers to a torus fracture, an incomplete fracture type, specifically affecting the lower 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 lower end of the fibula is the distal portion near the ankle 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 lower fibula.
• Limited range of motion in the 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 and rule out other injuries. Occasionally, additional imaging (e.g., CT or MRI) may be employed for complex cases requiring detailed visualization.

Treatment Options

Treatment typically involves immobilization with a cast or splint to allow healing. Pain management and activity modification are often recommended. In most cases, torus fractures heal without surgical intervention, though follow-up imaging may be used to monitor progress.

Prognosis and Follow-Up

Prognosis is generally favorable, with most fractures healing within 4–6 weeks. Follow-up care includes monitoring for pain resolution and restoring mobility. Physical therapy may be advised to regain strength and range of motion once healing is complete.

Complications

Rare complications include delayed healing, malunion, or persistent pain. Infection or nerve injury is uncommon but possible with severe trauma or improper immobilization.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Ensure safe play environments for children to reduce fall risks.
• Maintain bone health through adequate nutrition (e.g., calcium, vitamin D).
• Avoid activities that increase ankle twisting or direct impact to the lower leg.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or weight-bearing is impossible. Immediate care is needed if deformity, numbness, or circulation issues (e.g., cold toes) occur.

Tips for Medical Coders

Document the specific location (lower end of right fibula) and fracture type (torus) to ensure accurate coding. Include details on trauma mechanism, patient age, and imaging results to support the diagnosis. Verify laterality (right) and fracture completeness (incomplete) for precise code assignment.
