S52.241 Displaced spiral fracture of shaft of ulna, right arm

Name of the Condition

• Displaced spiral fracture of shaft of ulna, right arm

Summary

A displaced spiral fracture of the shaft of the ulna, right arm, is a break in the long, straight portion of the ulna bone (one of the two forearm bones) with a spiral pattern and misalignment of bone fragments. This fracture typically results from rotational forces and involves displacement, where the broken bone ends are not in their normal anatomical position.

Causes

Direct trauma to the forearm, such as from a fall, blow, or accident. High-impact injuries, including sports-related incidents or motor vehicle collisions. Indirect forces transmitted through the wrist or elbow, potentially causing a spiral break in the ulna shaft.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Previous fractures or bone abnormalities that may predispose to injury.
• Advanced age, which can reduce bone strength.

Symptoms

• Pain and tenderness localized to the forearm.
• Swelling and bruising around the injured area.
• Difficulty moving the arm, wrist, or hand due to pain or instability.
• Possible visible deformity if the fracture is displaced.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate alignment. Additional imaging (e.g., CT scans) may be used for complex fractures to assess displacement and spiral pattern.

Treatment Options

• Immobilization with a cast or splint to support healing.
• Pain management with medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs).
• Surgical intervention may be required for severe or displaced fractures to realign and stabilize the bone.

Prognosis and Follow-Up

Recovery depends on fracture severity, treatment, and patient factors. Immobilization and rehabilitation typically promote healing, but displaced fractures may require longer recovery. Follow-up imaging and physical therapy are often needed to monitor progress and restore function.

Complications

• Nonunion or malunion of the fracture.
• Nerve or blood vessel damage in the forearm.
• Chronic pain or stiffness in the arm.
• Infection (if surgical intervention is performed).

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the arm, or signs of nerve/vascular injury (e.g., numbness, coldness).

Tips for Medical Coders

Document the fracture type (spiral), displacement, and laterality (right arm) to support code S52.241. Ensure clinical notes specify the fracture pattern and alignment for accurate coding.
