S82.821A Torus fracture of lower end of right fibula, initial encounter for closed fracture

Name of the Condition

• Torus fracture of lower end of right fibula, initial encounter for closed fracture
• ICD-10 Code: S82.821A

Summary

This condition describes a torus fracture, an incomplete fracture, specifically affecting the lower end of the right fibula. Torus fractures involve buckling of the bone cortex without complete disruption, typically resulting from low-energy trauma. The lower end of the fibula is the distal portion near the ankle joint. This code is used for the initial encounter of a closed fracture, meaning the skin remains intact.

Causes

Torus fractures commonly result from low-energy trauma, such as falls, twisting injuries, or direct impacts to the lower leg. The mechanism often involves axial loading or bending forces that cause the bone to buckle rather than break completely. These injuries are more prevalent in children due to their softer, more pliable bones.

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.
• Difficulty bearing weight on the affected leg.
• 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. The fracture appears as a buckled cortex on imaging, distinguishing it from complete breaks.

Treatment Options

Treatment typically involves immobilization with a cast or splint to allow healing. Pain management and activity modification are recommended. Most torus fractures heal without surgery, and 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 appointments ensure proper healing and may include repeat imaging. Return to normal activities is gradual, guided by pain and stability.

Complications

Complications are rare but may include malunion, delayed healing, or persistent pain. Incomplete healing or improper immobilization can lead to long-term discomfort or functional limitations.

Lifestyle & Prevention

• Wear 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.
• Avoid activities that increase the risk of ankle or lower leg injuries.

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 occur, as these may indicate complications.

Tips for Medical Coders

Use S82.821A for the initial encounter of a closed torus fracture of the lower end of the right fibula. Document the fracture location (lower end of right fibula), laterality (right), and encounter type (initial) to ensure accurate coding. Closed fractures are specified as the skin remains intact.
