S62.173 Displaced fracture of trapezium [larger multangular], unspecified wrist

Name of the Condition

• Displaced fracture of trapezium [larger multangular], unspecified wrist

Summary

This condition involves a break in the trapezium bone of the wrist, with displacement of the bone fragments. The trapezium is one of the carpal bones located at the base of the thumb, and its fracture can affect wrist and thumb mobility. Displacement means the bone fragments are no longer aligned properly, which may require specific treatment to restore function.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the thumb or wrist, or a crushing injury. High-impact activities or accidents may also lead to fractures in this area.

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 displacement.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Surgical intervention: May be required for severe displacement or instability, involving realignment and fixation of the bone fragments.
• Rehabilitation: Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most fractures heal with proper treatment, but recovery time depends on severity and treatment. Follow-up appointments monitor healing and adjust care as needed. Full function may return, but some stiffness or weakness could persist.

Complications

• Chronic pain or arthritis in the wrist.
• Limited thumb mobility or grip strength.
• Nonunion or malunion of the fracture.
• Nerve or tendon damage in severe 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.
• Seek prompt care for wrist injuries to prevent complications.

When to Seek Professional Help

• Severe pain, swelling, or deformity after a wrist injury.
• Inability to move the thumb or wrist.
• Numbness, tingling, or coldness in the hand.
• Symptoms that worsen or do not improve with initial care.

Tips for Medical Coders

Document the displacement status and unspecified wrist location clearly. Ensure clinical notes support the diagnosis and treatment provided. Verify that the code aligns with the specific fracture details and any associated procedures.
