S63.074 Dislocation of distal end of right ulna

Name of the Condition

• Dislocation of distal end of right ulna

Summary

This condition involves the complete displacement of the distal end of the right ulna, the smaller bone in the forearm, at the wrist joint. The injury disrupts normal joint alignment and function, potentially causing pain, instability, and reduced mobility in the wrist and forearm.

Causes

Acute trauma, such as falls, direct impacts to the wrist, or forceful twisting, 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 contact sports or activities with a high 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 stabilize the joint.
• Closed reduction to manually realign the bone.
• Surgical intervention for severe or unstable dislocations.
• Physical therapy to restore strength and mobility.

Prognosis and Follow-Up

Recovery depends on injury severity and treatment. Most patients regain function with proper care, but stiffness or instability may persist. Follow-up visits monitor healing and guide rehabilitation.

Complications

• Chronic pain or instability.
• Nerve or vascular damage.
• Post-traumatic arthritis.
• Reduced range of motion.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Avoid repetitive wrist strain.
• Maintain joint strength through exercise.
• Seek prompt care for wrist injuries.

When to Seek Professional Help

Consult a healthcare provider if you experience severe pain, visible deformity, or inability to move the wrist after an injury.

Tips for Medical Coders

Document the specific side (right) and whether the dislocation is complete. Include details on trauma mechanism, imaging results, and treatment to support code specificity. Ensure alignment with clinical documentation for accurate coding.
