S52.121A Displaced fracture of head of right radius, initial encounter for closed fracture

Name of the Condition

• Common Name: Displaced Fracture of Head of Right Radius
• Medical Term: S52.121A

Summary

A displaced fracture of the head of the right radius is a break in the proximal portion of the radius bone, specifically involving the radial head, with the bone fragments shifted out of their normal alignment. This injury occurs in the right arm and is classified as a closed fracture (no open wound) during the initial encounter for treatment. The radial head is part of the elbow joint, and displacement may affect joint function or stability.

Causes

Displaced fractures of the radial head typically result from direct trauma to the elbow or forearm, such as falls onto an outstretched hand, impacts to the elbow, or rotational forces applied to the forearm. High-impact events, including motor vehicle accidents or sports injuries, are common causes. The displacement occurs when the force is sufficient to shift the fractured bone fragments from their original position.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, which may reduce bone density.
• Occupational hazards involving repetitive stress or trauma to the arm.

Symptoms

• Pain localized to the elbow or forearm.
• Swelling and bruising around the affected area.
• Difficulty rotating the forearm or moving the elbow.
• Possible deformity or instability in severe cases.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to visualize the fracture and determine displacement. CT or MRI scans may be used to evaluate associated soft tissue damage or joint involvement.

Treatment Options

Treatment depends on the severity of displacement and may include immobilization with a splint or cast, pain management, and physical therapy. Surgical intervention, such as open reduction and internal fixation, may be necessary for significantly displaced fractures to restore joint alignment and function.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time varies. Follow-up care typically involves monitoring healing progress through imaging and gradual resumption of activity. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include chronic pain, limited range of motion, arthritis in the elbow joint, or nonunion of the fracture. Nerve or blood vessel damage near the elbow may also occur in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Strengthen forearm and elbow muscles to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, increased swelling). Persistent pain or limited mobility after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the side (right), displacement status, and encounter type (initial for closed fracture) to accurately assign S52.121A. Ensure clinical notes specify the fracture as closed and the encounter as initial to meet coding guidelines.
