S63.071 Subluxation of distal end of right ulna

Name of the Condition

• Subluxation of distal end of right ulna

Summary

This condition involves the partial displacement of the distal end of the right ulna, where the bone is not fully aligned with its normal position at the wrist. The injury disrupts joint stability and may affect forearm or wrist function, potentially causing pain and reduced mobility.

Causes

Acute trauma, such as falls or direct impacts to the wrist, is a common cause. Repetitive stress or overuse from activities like manual labor or sports can also contribute. Underlying joint laxity or ligamentous instability may predispose individuals to these injuries.

Risk Factors

• Participation in high-impact sports or activities with a risk of falls.
• History of previous wrist or forearm injuries.
• Occupations involving heavy manual labor or repetitive wrist movements.
• Conditions affecting joint stability, such as hypermobility syndromes.

Symptoms

• Pain or tenderness near the wrist and forearm.
• A feeling of instability or limited range of motion.
• Swelling and possible bruising around the joint.
• Visible deformity or misalignment of the joint.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays or MRI, to view joint displacement and assess injury severity.

Treatment Options

• Immobilization with splints or casts to support healing.
• Manual reduction by a healthcare provider to realign the joint.
• Physical therapy to restore strength and mobility.
• Pain management with medications or other interventions.

Prognosis and Follow-Up

Most cases resolve with appropriate treatment, though recovery time varies. Follow-up care may include monitoring for stability and functional improvement. Persistent instability or pain may require further evaluation.

Complications

• Chronic instability or recurrent subluxation.
• Nerve or vascular damage in severe cases.
• Stiffness or reduced range of motion if not properly managed.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Avoid repetitive wrist stress or overuse.
• Maintain joint strength and flexibility through exercise.
• Seek prompt care for wrist injuries to prevent complications.

When to Seek Professional Help

Consult a healthcare provider if you experience severe pain, visible deformity, or inability to move the wrist. Immediate care is needed for signs of nerve or vascular injury, such as numbness or discoloration.

Tips for Medical Coders

Document the specific location (distal end of right ulna) and laterality (right) to support accurate coding. Ensure clinical notes specify subluxation and exclude complete dislocation or other joint injuries.
