S63.012 Subluxation of distal radioulnar joint of left wrist

Name of the Condition

• Subluxation of distal radioulnar joint of left wrist

Summary

Subluxation of the distal radioulnar joint (DRUJ) of the left wrist is a partial dislocation of the joint where the radius and ulna bones in the forearm are not fully aligned. This injury disrupts normal wrist stability and function, often resulting in pain and limited 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 the joint.
• Physical therapy to restore strength and mobility.
• Pain management with medications or injections.
• Surgical intervention for severe or persistent cases.

Prognosis and Follow-Up

Most cases resolve with conservative treatment, but recovery time varies. Follow-up care ensures proper healing and may include ongoing therapy. Persistent instability or pain may require further evaluation.

Complications

• Chronic wrist instability or recurrent subluxation.
• Arthritis or joint degeneration over time.
• Nerve or tendon damage from the injury.
• Reduced grip strength or functional impairment.

Lifestyle & Prevention

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

When to Seek Professional Help

Consult a healthcare provider if pain persists, mobility worsens, or deformity is present. Immediate care is needed for severe trauma or signs of nerve damage.

Tips for Medical Coders

Document the specific wrist (left) and confirm subluxation (partial displacement) rather than complete dislocation. Include details on injury mechanism, clinical findings, and treatment to support code specificity.
