S62.115A Nondisplaced fracture of triquetrum [cuneiform] bone, left wrist, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of triquetrum [cuneiform] bone, left wrist, initial encounter for closed fracture

Summary

This condition involves a break in the triquetrum bone of the left wrist without displacement of bone fragments. The triquetrum is one of the small carpal bones in the wrist, located on the ulnar (pinky) side, and plays a role in wrist stability. A nondisplaced fracture means the bone remains aligned, and the fracture is closed (skin intact). This type of injury typically results from trauma and may affect wrist function temporarily.

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 ulnar side of the left 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: Over-the-counter or prescription medications to reduce discomfort.
• Physical therapy: Exercises to restore strength and range of motion once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments may be needed to monitor healing and adjust treatment. Full recovery typically occurs within 6–8 weeks, depending on the individual’s health and adherence to recommendations.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Chronic pain or stiffness in the wrist.
• Arthritis in the wrist joint over time, though rare with nondisplaced fractures.

Lifestyle & Prevention

• Wear protective gear during high-risk activities (e.g., sports, work).
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if balance is a concern.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or there are signs of infection (e.g., redness, fever). Also, consult a healthcare provider if symptoms do not improve with initial treatment.

Tips for Medical Coders

Document the fracture as nondisplaced, specify the left wrist, and confirm it is a closed fracture with no displacement. Ensure the encounter is labeled as "initial" to reflect the first presentation for this injury. Include details about the mechanism of injury and any imaging results to support the diagnosis.
