S52.366 Nondisplaced segmental fracture of shaft of radius, unspecified arm

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, unspecified arm
ICD-10 Code: S52.366

Summary

A nondisplaced segmental fracture of the shaft of the radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the bone is separated into two or more fragments without misalignment. This injury typically results from significant trauma and may impair arm function depending on the degree of soft tissue damage. The "unspecified arm" designation indicates the affected side is not documented.

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.

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 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 rule out displacement. Clinical evaluation may also include assessing neurovascular status to check for nerve or blood vessel damage.

Treatment Options

Treatment typically includes immobilization with a cast or splint to stabilize the bone and allow healing. Surgical intervention may be required if the fracture is unstable or associated with soft tissue injury. Pain management and physical therapy are often part of the recovery process to restore function.

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment, as nondisplaced fractures tend to heal well. Follow-up appointments are necessary to monitor healing through imaging and assess functional recovery. Physical therapy may be recommended to regain strength and mobility.

Complications

Potential complications include malunion (improper healing), nonunion (failure to heal), nerve or blood vessel damage, or chronic pain. Infection may occur in open fractures. Long-term stiffness or reduced range of motion is also possible.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, maintaining bone health through diet and exercise, and avoiding falls by modifying the home environment. Strengthening exercises for the forearm and wrist may reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, redness). Numbness, tingling, or coldness in the hand or fingers also warrants prompt evaluation.

Tips for Medical Coders

Document the fracture as nondisplaced and segmental, specifying the shaft of the radius. Use "unspecified arm" when the side is not documented. Ensure clinical notes support the absence of displacement and the segmental nature of the fracture to justify the code.
