S52.231 Displaced oblique fracture of shaft of right ulna

Name of the Condition

• Displaced Oblique Fracture of Shaft of Right Ulna
• ICD Code: S52.231
• Also referred to as: Right Ulna Shaft Fracture

Summary

A displaced oblique fracture of the shaft of the right ulna is a break in the long, straight portion of the right ulna bone, where the fracture line is angled and the bone fragments are not aligned. This type of fracture involves the main body of the ulna and may result in instability or misalignment of the forearm.

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 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 along the forearm.
• Swelling and bruising around the injured area.
• Limited range of motion or difficulty moving the wrist or hand.
• Visible deformity or bump at the fracture site.

Diagnosis

Physical examination to assess swelling, bruising, and range of motion. Imaging tests, such as X-rays, to visualize the fracture and alignment. CT or MRI may be used for more detailed bone imaging if necessary.

Treatment Options

• Immobilization: Casting or splinting to keep the bone in position.
• Surgery: May be needed to realign and stabilize the fracture with plates, screws, or rods.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: To restore strength and mobility after healing.

Prognosis and Follow-Up

Most displaced oblique fractures of the ulna shaft heal well with proper treatment, though recovery time varies. Follow-up appointments are typically scheduled to monitor healing and adjust treatment as needed. Full function may return, but some residual stiffness or weakness is possible.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in an incorrect position.
• Nerve or blood vessel damage near the fracture site.
• Infection, particularly if surgery is performed.

Lifestyle & Prevention

• Use protective gear during high-risk activities like sports.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.
• Warm up properly before physical activity to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, numbness, or inability to move the arm. Contact a healthcare provider if swelling, pain, or bruising worsens after initial treatment.

Tips for Medical Coders

Document the fracture type (oblique), displacement, and laterality (right) clearly in the medical record. Ensure the fracture is specified as displaced to justify the use of S52.231. Include details about the mechanism of injury and any associated complications to support coding accuracy.
