S62.184 Nondisplaced fracture of trapezoid [smaller multangular], right wrist

Name of the Condition

• Nondisplaced fracture of trapezoid [smaller multangular], right wrist

Summary

This condition refers to a break in the trapezoid bone of the right wrist where the bone fragments remain in their normal anatomical position. The trapezoid is one of the small carpal bones in the wrist, located on the radial (thumb) side, and plays a role in wrist stability and movement. Nondisplaced fractures typically result from trauma and may involve minimal or no misalignment of the bone fragments.

Causes

Usually 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 radial side of the right wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and wrist 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 wrist and promote healing.
• Pain management: Medications or other therapies 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 follow-up care. Recovery time varies but typically ranges from several weeks to a few months. Regular follow-up appointments may be needed to monitor healing and adjust treatment as necessary.

Complications

• Delayed healing or nonunion of the fracture.
• Arthritis or stiffness in the wrist joint.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition 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, deformity, or inability to move the wrist after an injury. Persistent pain or difficulty with wrist function during recovery should also prompt a medical evaluation.

Tips for Medical Coders

Document the specific location (right wrist) and the nondisplaced nature of the fracture. Ensure clinical notes support the absence of displacement to justify this code. Verify that the trapezoid bone is clearly identified in the record, as this distinguishes it from other carpal bone fractures.
