S63.011 Subluxation of distal radioulnar joint of right wrist

Name of the Condition

• Subluxation of Distal Radioulnar Joint of Right Wrist

Summary

Subluxation of the distal radioulnar joint (DRUJ) of the right wrist is a partial dislocation of the joint where the radius and ulna bones in the forearm are not fully aligned. This injury affects wrist stability and function, often resulting in pain and limited mobility.

Causes

Trauma, such as falls or direct impact to the wrist, is a common cause. Repetitive stress from activities like sports or manual labor can also lead to joint displacement. Underlying ligamentous laxity may predispose individuals to this injury.

Risk Factors

• Participation in high-impact sports or activities with a risk of wrist injury.
• History of previous wrist or forearm injuries.
• Occupations involving repetitive wrist movements or heavy lifting.
• Inadequate protective gear during physical activities.

Symptoms

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

Diagnosis

Physical examination to assess tenderness, swelling, and joint stability. Imaging tests, such as X-rays or MRI, to confirm joint displacement and rule out fractures or soft tissue damage.

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 motion.
• Pain management with medications or modalities like ice.

Prognosis and Follow-Up

Most cases resolve with proper treatment, though recovery time varies. Follow-up care may include monitoring for stability and gradual return to activity. Persistent instability may require further intervention.

Complications

• Chronic wrist instability or recurrent subluxation.
• Nerve or tendon damage from the injury.
• Post-traumatic arthritis in the joint.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Avoid repetitive wrist strain through ergonomic adjustments.
• Strengthen wrist and forearm muscles to improve stability.

When to Seek Professional Help

Seek care if pain is severe, mobility is significantly limited, or deformity is present. Immediate evaluation is needed if numbness, tingling, or circulation issues occur.

Tips for Medical Coders

Document the specific side (right) and joint involved (distal radioulnar) to support accurate coding. Include details on injury mechanism, treatment, and follow-up to ensure comprehensive clinical documentation.
