S62.186 Nondisplaced fracture of trapezoid [smaller multangular], unspecified wrist

Name of the Condition

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

Summary

This condition refers to a break or crack in the trapezoid bone, one of the small carpal bones in the wrist, where the bone fragments remain in their normal alignment. The trapezoid is located on the radial (thumb) side of the wrist and plays a role in wrist stability and movement. Nondisplaced fractures typically result from trauma and may vary in severity, with the bone maintaining its structural integrity despite the injury.

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 in the radial side of the 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 therapies to reduce discomfort and inflammation.
• 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 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 chronic pain in the wrist over time.
• Nerve or tendon damage in rare cases.

Lifestyle & Prevention

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

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 and specify the wrist (unspecified) as per the code. Ensure clinical notes confirm the absence of displacement and the affected wrist side if known. Use this code for fractures of the trapezoid bone without displacement, aligning with ICD-10-CM guidelines.
