S52.231S Displaced oblique fracture of shaft of right ulna, sequela

Name of the Condition

• Displaced Oblique Fracture of Shaft of Right Ulna, Sequela
• ICD Code: S52.231S
• Also referred to as: Right Ulna Shaft Fracture (Sequela)

Summary

A displaced oblique fracture of the shaft of the right ulna, sequela, refers to a long-term complication or residual effect of a previous fracture of the right ulna bone. The fracture line is angled, and the bone fragments remain misaligned, resulting in persistent structural or functional changes. This code is used for encounters related to the aftermath of the initial injury, not the acute event.

Causes

The sequela arises from a prior displaced oblique fracture of the right ulna shaft. The original injury may have resulted from trauma, such as a fall, accident, or high-impact force to the forearm. The current condition reflects the lasting effects of that initial break, including misalignment or healing complications.

Risk Factors

• Inadequate initial treatment or healing of the original fracture.
• Poor bone healing due to age, nutrition, or underlying conditions like osteoporosis.
• High-impact activities or repetitive stress on the forearm during recovery.
• Delayed or incomplete rehabilitation after the initial injury.

Symptoms

• Chronic pain or discomfort in the forearm.
• Persistent swelling or deformity at the fracture site.
• Reduced range of motion in the wrist or elbow.
• Weakness or instability when using the affected arm.
• Possible nerve or tendon irritation from misaligned bone fragments.

Diagnosis

A physical examination assesses residual deformity, tenderness, and functional limitations. Imaging, such as X-rays or CT scans, evaluates bone alignment and healing. The diagnosis confirms the sequela by linking current findings to the history of the prior fracture.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to restore mobility, pain management, or surgical intervention to correct misalignment. Bracing or orthotics might support the forearm during recovery.

Prognosis and Follow-Up

Prognosis depends on the severity of the sequela and response to treatment. Regular follow-up monitors healing, function, and pain. Long-term management may be necessary to address chronic symptoms or mobility issues.

Complications

• Chronic pain or arthritis in the forearm joint.
• Nerve damage leading to numbness or weakness.
• Reduced grip strength or dexterity.
• Persistent deformity affecting appearance or function.

Lifestyle & Prevention

• Avoid activities that strain the forearm until cleared by a provider.
• Use protective gear during sports or high-risk tasks.
• Maintain bone health through nutrition and exercise to support recovery.
• Follow rehabilitation plans to optimize healing and function.

When to Seek Professional Help

Seek care if chronic pain worsens, mobility declines, or new symptoms (e.g., numbness, swelling) develop. Prompt evaluation helps address complications and adjust treatment.

Tips for Medical Coders

Use S52.231S for encounters related to the sequela of a displaced oblique fracture of the right ulna shaft. Document the history of the prior fracture and current residual effects to support code assignment. Ensure the encounter is for the sequela, not the acute injury.
