S62.175A Nondisplaced fracture of trapezium [larger multangular], left wrist, initial encounter for closed fracture

Name of the Condition

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

Summary

This condition refers to a break in the trapezium bone of the left wrist without displacement of bone fragments, occurring during the initial encounter for a closed fracture. The trapezium is a small carpal bone at the base of the thumb, essential for thumb movement and grip. Nondisplaced fractures mean the bone fragments remain aligned, which may simplify treatment and recovery compared to displaced fractures.

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 or stiffness in the wrist or thumb joint over time.
• Nerve or tendon damage in rare cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through a balanced diet and exercise.
• Avoid falls by using assistive devices if needed, 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, or if symptoms worsen despite initial care.

Tips for Medical Coders

Document the fracture as nondisplaced, specify the left 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.
