S62.172S Displaced fracture of trapezium [larger multangular], left wrist, sequela

Name of the Condition

• Displaced fracture of trapezium [larger multangular], left wrist, sequela

Summary

This condition represents a displaced fracture of the trapezium bone in the left wrist, with residual effects from the injury. The trapezium is a carpal bone at the base of the thumb, and displacement means the bone fragments are misaligned. The term "sequela" indicates this is a complication or long-term effect following the initial fracture, such as chronic pain, limited mobility, or deformity.

Causes

The sequela arises from a prior displaced fracture of the trapezium, typically caused by trauma like a fall onto an outstretched hand, a direct blow to the wrist, or a crushing injury. The initial injury may have been untreated, improperly healed, or resulted in persistent damage to the bone or surrounding structures.

Risk Factors

• Prior wrist trauma or fracture history.
• Inadequate initial treatment or nonunion of the original fracture.
• Underlying conditions affecting bone healing, such as osteoporosis or diabetes.
• High-impact activities or occupations increasing wrist injury risk.

Symptoms

• Chronic pain or discomfort at the base of the thumb.
• Persistent swelling or tenderness in the wrist.
• Reduced range of motion or stiffness in the thumb or wrist.
• Visible deformity or instability in the affected area.
• Numbness or tingling due to nerve irritation.

Diagnosis

Evaluation includes a physical exam to assess pain, mobility, and deformity. Imaging, such as X-rays or CT scans, confirms the fracture's status and any residual displacement. Additional tests may check for arthritis or nerve damage. Documentation of the sequela must link to the original injury.

Treatment Options

• Conservative management: Physical therapy to improve mobility and strength.
• Pain relief: Medications or injections for chronic discomfort.
• Surgical intervention: Procedures to realign bones, remove scar tissue, or fuse joints if severe.
• Assistive devices: Splints or braces to stabilize the wrist during healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the sequela and response to treatment. Some patients experience long-term limitations, while others regain function with therapy. Regular follow-ups monitor healing, mobility, and pain levels. Complications like arthritis may require ongoing management.

Complications

• Chronic pain or arthritis in the wrist.
• Persistent stiffness or reduced thumb function.
• Nerve damage leading to numbness or weakness.
• Nonunion or malunion of the original fracture.
• Secondary injuries from altered biomechanics.

Lifestyle & Prevention

• Avoid repetitive wrist stress or high-impact activities.
• Use protective gear during sports or work.
• Maintain bone health with proper nutrition and exercise.
• Follow post-injury rehabilitation to minimize long-term effects.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling occurs, or mobility significantly declines. Immediate attention is needed for sudden severe pain, deformity, or signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the sequela clearly, linking it to the original displaced fracture. Ensure the left wrist and trapezium involvement are specified. Use this code only for sequelae, not initial encounters. Verify that the fracture's displacement and chronic effects are well-documented to support coding accuracy.
