S52.364 Nondisplaced segmental fracture of shaft of radius, right arm

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, right arm
ICD-10 Code: S52.364

Summary

A nondisplaced segmental fracture of the shaft of the radius is a specific type of fracture involving two separate breaks in the long, outer bone of the forearm (radius) between the elbow and wrist, with the bone fragments remaining in their original alignment. This injury typically results from significant trauma and may require stabilization to prevent displacement and restore function. The "right arm" specification indicates the affected side.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, high-impact blows to the forearm, or accidents involving twisting forces at the wrist or elbow. Motor vehicle collisions, sports injuries, or forceful impacts may also cause the bone to break into multiple segments without misalignment.

Risk Factors

• Participation in contact sports or activities with a high risk of falls
• Osteoporosis or weakened bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving repetitive stress or heavy lifting

Symptoms

• Sudden, severe pain at the injury site
• Swelling, bruising, or deformity of the forearm
• Inability to move the wrist or forearm
• Visible bone protrusion through the skin (in open fractures)
• Numbness or tingling in the hand or fingers

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays or CT scans to confirm the fracture pattern and alignment. The nondisplaced nature of the fracture is identified by the absence of fragment misalignment on imaging.

Treatment Options

Treatment may include immobilization with a cast or splint to stabilize the bone and promote healing. Surgical intervention is less common for nondisplaced fractures but may be considered if there is risk of displacement or associated soft tissue damage. Pain management and physical therapy are often part of the recovery process.

Prognosis and Follow-Up

Prognosis is generally favorable with proper immobilization and follow-up care. Healing typically occurs within 6–8 weeks, but full functional recovery may take longer. Regular follow-up appointments are necessary to monitor healing and adjust treatment as needed.

Complications

Potential complications include delayed union or nonunion of the fracture, infection (if open), nerve or vascular injury, or progression to a displaced fracture if immobilization is inadequate. Long-term stiffness or weakness in the forearm may also occur.

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 muscles through regular exercise

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, increased swelling). Prompt evaluation is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

When coding S52.364, ensure documentation specifies the nondisplaced nature of the segmental fracture and the right arm involvement. Verify that the fracture is confirmed by imaging and that no displacement or associated injuries are present. Accurate documentation of the fracture pattern and affected side is critical for correct code assignment.
