S52.331A Displaced oblique fracture of shaft of right radius, initial encounter for closed fracture

Name of the Condition

Displaced oblique fracture of shaft of right radius, initial encounter for closed fracture
ICD-10 Code: S52.331A

Summary

A displaced oblique fracture of the shaft of the right radius involves a break in the long, outer bone of the forearm (radius) between the elbow and wrist, with the fracture line running at an angle and the bone fragments shifted out of alignment. The term "closed" indicates the skin remains intact, and "initial encounter" denotes the first episode of care for this injury. This type of fracture may affect arm function depending on the degree of displacement and requires evaluation to determine appropriate management.

Causes

This fracture typically results from direct trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving twisting forces at the wrist or elbow. High-impact events like motor vehicle collisions or sports injuries can also cause the bone to break in an oblique pattern.

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
• Numbness or tingling in the hand or fingers (if nerve involvement)

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays to confirm the fracture type, displacement, and whether the injury is open or closed. Additional tests may be ordered if nerve or vascular involvement is suspected.

Treatment Options

Treatment depends on the fracture's severity and displacement. Stable fractures may be managed with immobilization (e.g., casting or splinting) and pain relief. Displaced fractures often require realignment (reduction) and may need surgical intervention with plates, screws, or rods to stabilize the bone. Physical therapy is typically recommended during recovery to restore function.

Prognosis and Follow-Up

Most displaced oblique fractures of the radius heal well with appropriate treatment, though recovery time varies based on fracture severity and patient factors. Follow-up appointments are necessary to monitor healing, assess alignment, and adjust treatment as needed. Full function may return, but some stiffness or strength loss can occur, particularly with more complex injuries.

Complications

• Nonunion (failure of the bone to heal)
• Malunion (healing in an incorrect position)
• Nerve or blood vessel damage
• Infection (rare, more common in open fractures)
• Chronic pain or stiffness

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 to improve resilience
• Follow safety protocols in occupations involving heavy lifting or repetitive stress

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, inability to move the arm, numbness or tingling, or signs of infection (e.g., redness, warmth, fever) after an injury.

Tips for Medical Coders

Document the fracture type (oblique), displacement, laterality (right), and encounter type (initial, closed) to support accurate coding. Ensure clinical notes specify the fracture pattern and whether the injury is open or closed, as these details are critical for correct code assignment.
