S52.521 Torus fracture of lower end of right radius

Name of the Condition

• Torus fracture of lower end of right radius

Summary

A torus fracture of the lower end of the right radius is a specific type of incomplete fracture occurring in the distal radius, near the wrist. This injury typically involves a buckling or compression of the bone cortex without complete displacement, often seen in children due to their more flexible bone structure. The fracture may result in localized pain and swelling but generally maintains bone alignment.

Causes

Typically results from trauma such as a fall onto an outstretched hand, direct impact to the wrist, or a forceful bending injury. The mechanism often involves axial loading or a sudden twist applied to the wrist, which causes the bone to buckle rather than break completely.

Risk Factors

• Increased likelihood with activities prone to falls, such as sports or play in children.
• Higher risk in pediatric populations due to developing bone structure.
• Greater susceptibility in individuals with conditions affecting bone flexibility or strength.

Symptoms

• Pain and swelling localized to the wrist area.
• Tenderness over the distal radius.
• Possible mild deformity or visible bulging at the fracture site.
• Limited range of motion in the wrist or forearm.

Diagnosis

Physical examination to assess pain, swelling, and tenderness. Imaging tests, primarily X-rays, to confirm the torus fracture pattern and rule out other injuries. The fracture appears as a buckled or compressed area of the bone cortex on imaging.

Treatment Options

• Immobilization using a cast or splint to support healing and limit movement.
• Pain management with over-the-counter or prescribed medications.
• Follow-up imaging to monitor healing progress, if clinically indicated.

Prognosis and Follow-Up

Most torus fractures heal well with immobilization, and recovery is typically rapid, especially in children. Follow-up appointments may be scheduled to assess healing and remove the immobilization device once the bone is stable.

Complications

• Rare risk of delayed union or nonunion if immobilization is insufficient.
• Possible residual stiffness or minor functional limitations in the wrist.
• Uncommon nerve or soft tissue irritation near the fracture site.

Lifestyle & Prevention

• Use protective gear during activities with fall risks, such as sports.
• Ensure proper supervision for children during play to minimize injury chances.
• Maintain bone health through adequate nutrition and exercise, as appropriate for age.

When to Seek Professional Help

• Persistent or worsening pain, swelling, or deformity.
• Inability to move the wrist or forearm after injury.
• Numbness, tingling, or changes in hand sensation.
• Signs of infection, such as redness, warmth, or drainage at the injury site.

Tips for Medical Coders

Document the specific location (right radius) and fracture type (torus) to ensure accurate coding. Include details about the mechanism of injury, imaging findings, and treatment provided to support code assignment. Verify that the fracture is confirmed and documented as incomplete to align with the torus fracture definition.
