S52.529P Torus fracture of lower end of unspecified radius, subsequent encounter for fracture with malunion

Name of the Condition

• Torus fracture of lower end of unspecified radius, subsequent encounter for fracture with malunion

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 specifies a subsequent encounter for a fracture with malunion, indicating the bone has healed in a non-anatomical position.

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 diagnosis of malunion is confirmed by radiographic evidence of abnormal bone healing.

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.
• Surgical intervention may be considered for significant malunion affecting function.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Most patients recover with conservative management, but residual stiffness or deformity may persist. Follow-up imaging and clinical assessments monitor healing progress and guide rehabilitation.

Complications

• Chronic pain or discomfort.
• Reduced range of motion.
• Long-term functional limitations.
• Increased risk of future fractures in the affected area.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health with adequate nutrition (e.g., calcium, vitamin D).
• Avoid falls by improving home safety (e.g., removing tripping hazards).
• Engage in regular exercise to strengthen bones and muscles.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or movement becomes severely restricted. Prompt evaluation is necessary if numbness, tingling, or circulation issues occur, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

This code is used for a subsequent encounter of a torus fracture of the lower end of the unspecified radius with malunion. Document the encounter type (subsequent) and confirm the presence of malunion through clinical and radiographic findings. Ensure the fracture is not open or with delayed healing, as these require different codes.
