S52.112K Torus fracture of upper end of left radius, subsequent encounter for fracture with nonunion

Name of the Condition

• Common Name: Torus Fracture of Upper End of Left Radius with Nonunion
• Medical Term: S52.112K

Summary

A torus fracture of the upper end of the left radius is a stable, incomplete break in the proximal portion of the left radius bone, near the elbow joint. This type of fracture is characterized by a buckling or compression of the bone cortex without significant displacement. The code S52.112K indicates a subsequent encounter for fracture with nonunion, meaning the fracture has failed to heal properly after an expected period.

Causes

Torus fractures of the upper end of the radius typically result from low-impact trauma, such as a fall onto an outstretched hand or a direct blow to the elbow. The force applied is usually insufficient to cause a complete fracture but sufficient to buckle the bone's outer layer, particularly in individuals with flexible bone structures. Nonunion may occur due to inadequate immobilization, poor blood supply, or other factors affecting healing.

Risk Factors

• Participation in activities with a risk of falls or minor impacts, such as sports or play.
• Age, as torus fractures are more prevalent in children and adolescents due to their developing bone structure.
• Osteopenia or other conditions affecting bone density in younger individuals.
• Factors that impair healing, such as smoking, diabetes, or nutritional deficiencies.

Symptoms

• Persistent localized pain at the elbow or forearm.
• Mild to moderate swelling or bruising around the affected area.
• Difficulty rotating the forearm or moving the elbow.
• Tenderness upon palpation of the upper radius.
• Possible visible deformity if nonunion is severe.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate for nonunion. The presence of a persistent fracture line or lack of callus formation on imaging may indicate nonunion. Additional tests, like bone scans, may be performed to assess blood flow and healing potential.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace to stabilize the fracture. Surgical intervention, such as bone grafting or internal fixation, may be necessary for nonunion. Physical therapy is often recommended to restore function and strength. Pain management and monitoring for complications are also part of the care plan.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With appropriate intervention, many fractures can heal, but recovery may be prolonged. Regular follow-up appointments are necessary to monitor healing progress, adjust treatment, and address any complications. Long-term outcomes may include residual stiffness or weakness in the affected arm.

Complications

• Chronic pain or discomfort.
• Limited range of motion in the elbow or forearm.
• Increased risk of future fractures.
• Potential need for additional surgery if nonunion persists.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Follow post-treatment instructions carefully to promote healing.
• Engage in gradual, supervised physical therapy to restore function.

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, or difficulty moving the arm after a fracture. Contact a healthcare provider if symptoms worsen or if there are signs of infection, such as redness, warmth, or fever. Prompt evaluation is important for managing nonunion and preventing further complications.

Tips for Medical Coders

When coding S52.112K, ensure the documentation specifies a torus fracture of the upper end of the left radius with nonunion during a subsequent encounter. Verify that the encounter is for fracture care and that nonunion is clearly documented. Code sequencing should reflect the nature of the fracture and the status of healing. Accurate documentation of laterality (left) and the presence of nonunion is critical for correct coding.
