S52.529A Torus fracture of lower end of unspecified radius, initial encounter for closed fracture

Name of the Condition

• Torus fracture of lower end of unspecified radius, initial encounter for closed fracture

Summary

A torus fracture of the lower end of the unspecified radius is an incomplete fracture involving the distal portion of the radius bone, near the wrist. This injury typically presents as a buckling or compression of the bone cortex without complete displacement, often seen in children due to their more flexible bone structure. The fracture is generally stable and may result in localized pain and swelling but maintains bone alignment. This code specifies an initial encounter for a closed fracture, meaning the skin is intact and the fracture has not pierced through it.

Causes

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

Risk Factors

• Higher incidence in children and adolescents due to developing bone structure.
• Activities with a risk of falls, such as sports or play.
• Lack of protective gear during high-impact activities.

Symptoms

• Localized pain and swelling at the wrist.
• Tenderness to touch the affected area.
• Mild limitation in wrist movement.
• Possible visible deformity in severe cases.

Diagnosis

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

Treatment Options

• Immobilization with a cast or splint to support healing and limit movement.
• Pain management with over-the-counter or prescription medications.
• Follow-up appointments to monitor healing and adjust treatment as needed.

Prognosis and Follow-Up

Most torus fractures heal well with proper immobilization and care, typically within 4-6 weeks. Follow-up may include repeat imaging to confirm healing and assessment of wrist function. Full recovery is common, with most patients regaining normal range of motion and strength.

Complications

• Rarely, malunion or delayed healing if immobilization is insufficient.
• Persistent pain or stiffness in the wrist.
• Nerve or tendon irritation near the fracture site.

Lifestyle & Prevention

• Use protective gear during sports or activities with fall risks.
• Ensure proper supervision for children during play.
• Maintain bone health through adequate nutrition, including calcium and vitamin D.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or there is numbness, tingling, or loss of function in the hand or fingers. Immediate care is needed for severe deformity or inability to move the wrist.

Tips for Medical Coders

Document the encounter as initial for a closed fracture. Specify the radius as unspecified, and confirm the fracture type (torus) and location (lower end) in clinical notes. Ensure documentation supports the closed nature of the fracture and the initial encounter status.
