S82.162A Torus fracture of upper end of left tibia, initial encounter for closed fracture

Name of the Condition

• Torus fracture of upper end of left tibia, initial encounter for closed fracture

Summary

This condition involves a torus (buckle) fracture of the upper end of the left tibia, occurring during the initial encounter for a closed fracture. A torus fracture is a type of incomplete fracture where the bone buckles but does not fully break, typically affecting the metaphyseal region near the knee. The fracture is closed, meaning the skin remains intact, and this is the first encounter for this specific injury.

Causes

Traumatic injury is the primary cause, often resulting from a direct blow or axial load to the tibia, such as a fall onto the knee or a sudden impact. Low-energy forces, common in pediatric or adolescent populations, can lead to this type of fracture due to the relative flexibility of growing bones.

Risk Factors

• Participation in activities with a risk of falls or direct impacts to the knee.
• Age, as torus fractures are more common in children and adolescents with developing bones.
• Osteoporosis or bone-weakening conditions that reduce bone density.
• Previous injuries to the tibia or knee joint that may weaken the bone.

Symptoms

• Pain and swelling localized to the upper tibia or knee area.
• Tenderness to palpation over the fracture site.
• Possible mild deformity or buckling of the bone, though less severe than with complete fractures.
• Inability to bear weight on the affected leg.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to evaluate the fracture type, displacement, and involvement of the knee joint. CT scans or MRIs may be considered if additional detail is needed.

Treatment Options

Treatment typically includes immobilization with a cast or brace to stabilize the fracture. Pain management and activity modification are recommended. Most torus fractures heal without surgery, but follow-up imaging may be used to monitor healing.

Prognosis and Follow-Up

Prognosis is generally favorable, with most fractures healing within 4–6 weeks. Follow-up appointments are important to assess healing and adjust treatment as needed. Weight-bearing restrictions may be gradually lifted based on clinical progress.

Complications

Complications are rare but may include malunion, delayed healing, or persistent pain. In rare cases, associated injuries to ligaments or cartilage may occur.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate nutrition and exercise.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or weight-bearing becomes impossible. Also, consult a provider if new deformity or numbness develops.

Tips for Medical Coders

Document the fracture location (left tibia), type (torus), encounter status (initial), and whether the fracture is closed. Ensure clinical notes specify the absence of open wounds or displacement to support the code.
