S52.529S Torus fracture of lower end of unspecified radius, sequela

Name of the Condition

• Torus fracture of lower end of unspecified radius, sequela

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 occurring 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 is used for a sequela, indicating a condition resulting from the fracture that persists after the acute phase has resolved.

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 is identified by its characteristic buckling appearance on imaging.

Treatment Options

• Immobilization with a cast or splint to support healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore strength and mobility once healing progresses.
• Monitoring for complications or delayed union.

Prognosis and Follow-Up

Most torus fractures heal well with proper immobilization and care. Follow-up appointments are typically scheduled to assess healing progress, often with repeat imaging if needed. Full recovery is expected, though mild residual symptoms may persist in some cases.

Complications

• Delayed union or nonunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Malalignment if the fracture was not properly immobilized.
• Nerve or tendon irritation near the fracture site.

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Practice safe falling techniques to reduce wrist injury risk.
• Maintain bone health through adequate nutrition and exercise.
• Avoid activities that increase fall risk until fully healed.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to move the wrist, visible deformity, or signs of infection (e.g., redness, fever). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

This code is used for a sequela of a torus fracture of the lower end of the unspecified radius. Document the residual effects or complications resulting from the fracture, such as chronic pain or functional limitations, to support the use of this code. Ensure the fracture is no longer in the acute healing phase and that the sequela is directly attributable to the original injury.
