S63.015 Dislocation of distal radioulnar joint of left wrist

Name of the Condition

• Dislocation of distal radioulnar joint of left wrist

Summary

Dislocation of the distal radioulnar joint (DRUJ) of the left wrist is a complete displacement of the joint where the radius and ulna bones in the forearm are no longer aligned. This injury disrupts normal wrist stability and function, often resulting in pain, instability, 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.
• Closed reduction to realign the joint, often under anesthesia.
• Surgical intervention for severe or unstable dislocations.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Most patients recover with proper management, but some may experience long-term stiffness or instability. Follow-up care includes monitoring for complications and gradual return to activity.

Complications

• Chronic wrist instability or pain.
• Stiffness or reduced range of motion.
• Nerve or vascular damage in severe cases.
• Risk of recurrent dislocation.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Avoid repetitive wrist strain through proper ergonomics.
• Strengthen forearm and wrist muscles to improve stability.
• Seek prompt treatment for wrist injuries to prevent progression.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, visible deformity, or inability to move the wrist after an injury. Persistent pain, swelling, or instability after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the laterality (left wrist) and confirm the diagnosis of complete dislocation (not subluxation) to ensure accurate coding. Include details on trauma mechanism, imaging findings, and treatment approach to support clinical specificity.
