S62.174 Nondisplaced fracture of trapezium [larger multangular], right wrist

Name of the Condition

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

Summary

This condition refers to a break or crack in the trapezium bone of the right 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 or therapies to reduce discomfort.
• Rehabilitation: Physical therapy 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 several weeks to a few months. Regular follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Delayed healing or nonunion if not properly immobilized.
• Arthritis or stiffness in the wrist or thumb joint.
• Nerve or tendon irritation near the fracture site.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving balance and home safety.

When to Seek Professional Help

Seek immediate care if experiencing severe pain, swelling, or inability to move the thumb, or if the wrist appears deformed.

Tips for Medical Coders

Document the nondisplaced nature of the fracture and specify the right wrist. Ensure clinical notes support the absence of fragment displacement to justify this code.
