S62.171A Displaced fracture of trapezium [larger multangular], right wrist, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of trapezium [larger multangular], right wrist, initial encounter for closed fracture

Summary

This condition involves a break in the trapezium bone of the right wrist, where the bone fragments are displaced from their normal position. The trapezium is one of the carpal bones in the wrist, located at the base of the thumb. This is an initial encounter for a closed fracture, meaning the skin is intact and the fracture has not been previously treated. Displacement may affect wrist stability and function, requiring appropriate management to promote healing.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a twisting injury. High-impact activities or accidents may also lead to fractures in this specific bone.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous wrist injuries or fractures.

Symptoms

• Pain, swelling, and tenderness in the thumb or radial (thumb-side) wrist area.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and thumb/wrist mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent and displacement.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications like NSAIDs to reduce pain and inflammation.
• Physical therapy: To restore strength and range of motion after healing.
• Surgical intervention: May be required for severe displacement or instability.

Prognosis and Follow-Up

Most displaced fractures of the trapezium heal with proper immobilization and follow-up care. Recovery time varies but typically ranges from 6 to 12 weeks. Regular follow-up appointments are necessary to monitor healing and adjust treatment as needed. Long-term function depends on the severity of the fracture and adherence to rehabilitation.

Complications

• Chronic pain or stiffness in the wrist or thumb.
• Arthritis in the affected joint due to improper healing.
• Nerve or tendon damage in severe cases.
• Reduced grip strength or range of motion.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through a balanced diet and exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.
• Warm up and stretch before physical activities to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a wrist injury. Consult a healthcare provider if symptoms worsen or do not improve with initial care, or if you notice numbness, tingling, or difficulty moving the thumb.

Tips for Medical Coders

Document the specific bone (trapezium), side (right), displacement status, and encounter type (initial, closed) to ensure accurate coding. Include details about the mechanism of injury, clinical findings, and imaging results to support the diagnosis. Verify that the fracture is not open or previously treated, as this affects code assignment.
