S52.365B Nondisplaced segmental fracture of shaft of radius, left arm, initial encounter for open fracture type I or II

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, left arm, initial encounter for open fracture type I or II
ICD-10 Code: S52.365B

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 that remain in their original alignment. This injury typically results from significant trauma and may impair arm function depending on associated soft tissue damage. The "nondisplaced" nature means the bone fragments are not shifted out of position, which can influence treatment and recovery. The "open fracture type I or II" designation indicates a break in the skin with minimal contamination, requiring specific management considerations.

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 displacing them. Open fractures result when the broken bone pierces the skin, often from the same traumatic events.

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 to confirm the fracture pattern and displacement. CT scans may be used for detailed visualization of complex fractures. Open fractures require evaluation for wound size, contamination, and soft tissue damage to determine the appropriate treatment approach.

Treatment Options

Treatment focuses on stabilizing the fracture and managing the open wound. Nondisplaced fractures may be managed with immobilization (e.g., casting or splinting) and close monitoring. Open fractures often require surgical intervention to clean the wound, reduce the fracture, and stabilize the bone with hardware (e.g., plates or screws). Antibiotics and tetanus prophylaxis are standard for open fractures to prevent infection.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, associated soft tissue damage, and adherence to treatment. Nondisplaced fractures generally heal well with proper immobilization, while open fractures may have a longer recovery due to infection risk. Follow-up appointments are necessary to monitor healing, assess functional recovery, and adjust treatment as needed. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include infection (especially with open fractures), nonunion or malunion of the fracture, nerve or vascular damage, and chronic pain or stiffness. Open fractures carry a higher risk of infection, which may require additional interventions. Long-term complications can include reduced range of motion or functional impairment.

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 (e.g., removing tripping hazards). For individuals with osteoporosis, medications and regular bone density checks can reduce fracture risk. Prompt treatment of minor injuries may prevent progression to more severe fractures.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible bone protrusion, or inability to move the arm after an injury. Open fractures require urgent care to reduce infection risk. Contact a healthcare provider if pain worsens, swelling increases, or signs of infection (e.g., redness, pus) develop during recovery.

Tips for Medical Coders

Document the fracture type (segmental, nondisplaced), location (shaft of radius, left arm), and encounter details (initial for open fracture type I or II) to ensure accurate coding. Note the open fracture classification (type I or II) and any associated injuries or treatments. Verify that the code aligns with the clinical documentation to reflect the specific nature of the injury and management.
