S62.175 Nondisplaced fracture of trapezium [larger multangular], left wrist

Name of the Condition

• Nondisplaced fracture of trapezium [larger multangular], left wrist

Summary

This condition refers to a break or crack in the trapezium bone of the left wrist without displacement of bone fragments. The trapezium is a small carpal bone located at the base of the thumb, playing a key role in thumb movement and grip. Nondisplaced fractures mean the bone fragments remain in their normal alignment, which may influence treatment and recovery.

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 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: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Recovery time varies but typically ranges from 4 to 6 weeks. Regular follow-up appointments may be needed to monitor healing and adjust treatment as necessary.

Complications

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

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or inability to move the thumb, or if symptoms worsen after initial treatment.

Tips for Medical Coders

Document the specific location (left wrist) and the nondisplaced nature of the fracture. Ensure clinical notes support the absence of displacement to justify the code. Include details about trauma mechanism or associated injuries if relevant for accurate coding.
