S62.11 Fracture of triquetrum [cuneiform] bone of wrist

Name of the Condition

• Fracture of triquetrum [cuneiform] bone of wrist

Summary

This condition involves a break or crack in the triquetrum bone, one of the small carpal bones in the wrist. The triquetrum is located on the ulnar (pinky) side of the wrist and plays a role in wrist stability and movement. Fractures in this area typically result from trauma and may vary in severity, with or without displacement of bone fragments.

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 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 area and promote healing.
• Pain management: Medications like NSAIDs to reduce pain and inflammation.
• Physical therapy: To restore strength and mobility after initial healing.

Prognosis and Follow-Up

Most fractures of the triquetrum heal well with proper immobilization and care. Follow-up imaging may be needed to ensure proper healing. Recovery time varies but typically ranges from several weeks to a few months, depending on fracture severity. Regular follow-up with a healthcare provider is recommended to monitor progress.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis in the wrist joint due to improper alignment or damage.
• Nerve or tendon injury in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through a balanced diet and exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, deformity, or inability to move the wrist after an injury. Persistent pain or difficulty with wrist function after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the specific bone involved (triquetrum) and any details about the fracture, such as displacement or open/closed status, to ensure accurate coding. Note the laterality (e.g., left, right, bilateral) if specified, as this may impact code assignment. Include clinical details that support the diagnosis for thorough documentation.
