S72.472A Torus fracture of lower end of left femur, initial encounter for closed fracture

Name of the Condition

• Torus fracture of lower end of left femur, initial encounter for closed fracture

Summary

This condition involves a torus (buckle) fracture at the distal (lower) end of the left femur, the thigh bone, near the knee joint. A torus fracture is an incomplete break where the bone cortex buckles rather than fully fractures. The injury is closed (skin intact) and occurs during the initial encounter. Torus fractures are common in children due to the flexibility of their bones and typically result from low-energy trauma.

Causes

Low-impact trauma, such as falls from standing height or minor collisions. Direct force applied to the thigh or knee region. Repetitive stress or overuse in rare cases.

Risk Factors

• Pediatric age group, particularly children with developing bones.
• Participation in activities with a risk of falls or minor impacts.
• Underlying bone conditions that may weaken structural integrity.

Symptoms

• Localized pain at the fracture site, often mild to moderate.
• Swelling or tenderness around the knee or thigh.
• Possible mild deformity or "buckling" of the bone.
• Limited range of motion in the affected leg.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays, to confirm the torus fracture pattern and rule out other injuries. Clinical correlation with the mechanism of injury.

Treatment Options

Treatment typically involves immobilization with a cast or brace to allow healing. Pain management may include over-the-counter or prescription medications. Physical therapy may be recommended to restore strength and mobility once healing progresses. Most torus fractures heal without surgery.

Prognosis and Follow-Up

Prognosis is generally favorable, with most fractures healing within 4–6 weeks. Follow-up appointments monitor healing and functional recovery. Return to normal activities is gradual, guided by pain levels and mobility.

Complications

Rare complications include malunion (improper healing) or persistent pain. Infection is unlikely due to the closed nature of the fracture. Long-term issues, such as growth plate disturbances, are uncommon.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use protective gear during sports or play. Ensure safe environments to reduce fall risks, especially for children.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Immediate attention is needed for severe pain, deformity, or inability to bear weight.

Tips for Medical Coders

Document the fracture location (left femur), type (torus), encounter stage (initial), and whether the fracture is closed. Include details on the mechanism of injury and any imaging results to support coding. Ensure documentation aligns with the specificity of S72.472A.
