S62.174A Nondisplaced fracture of trapezium [larger multangular], right wrist, initial encounter for closed fracture

Name of the Condition

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

Summary

This condition describes a break in the trapezium bone of the right wrist where the bone fragments remain in their normal alignment, and the fracture is closed (skin is intact). The trapezium is a small carpal bone at the base of the thumb, essential for thumb movement and grip. Nondisplaced fractures typically result from trauma and may not require surgical intervention, depending on the extent of the injury.

Causes

Usually caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the thumb or 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 at the base of the thumb.
• 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 mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent and alignment.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Over-the-counter or prescription medications to reduce discomfort.
• Physical therapy: Exercises to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments are typically scheduled to monitor healing and adjust treatment as needed. Full recovery may take several weeks to months, depending on the individual's health and adherence to care instructions.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Arthritis in the wrist or thumb joint over time.
• Persistent pain or stiffness in the affected area.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as sports or manual labor.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid falls by using assistive devices if balance is a concern, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a wrist injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the fracture as nondisplaced, specify the right wrist, and confirm it is an initial encounter for a closed fracture. Ensure clinical notes support the absence of displacement and the closed nature of the injury to accurately assign this code.
