S62.115 Nondisplaced fracture of triquetrum [cuneiform] bone, left wrist

Name of the Condition

• Nondisplaced fracture of triquetrum [cuneiform] bone, left wrist

Summary

This condition involves a break or crack in the triquetrum bone of the left wrist without displacement of bone fragments. The triquetrum is one of the small carpal bones on the ulnar (pinky) side of the wrist, contributing to wrist stability and movement. Nondisplaced fractures typically result from trauma and may present with localized pain and swelling, though the bone fragments remain aligned.

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.
• Monitoring: Regular follow-up to ensure proper healing and alignment.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with immobilization and rest. Follow-up appointments may include repeat imaging to confirm healing. Full recovery typically occurs within 6–8 weeks, though individual timelines vary based on injury severity and patient factors.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Chronic pain or stiffness in the wrist.
• Arthritis or reduced wrist function in rare cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, falls).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive wrist stress or improper lifting techniques.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or numbness/tingling develops in the hand. Follow up with a healthcare provider if symptoms persist beyond initial treatment or if mobility does not improve.

Tips for Medical Coders

Document the nondisplaced nature of the fracture and specify the left wrist. Include details on trauma mechanism, imaging results, and treatment provided to support code specificity. Ensure alignment with clinical documentation for accurate coding.
