S62.111S Displaced fracture of triquetrum [cuneiform] bone, right wrist, sequela

Name of the Condition

• Displaced fracture of triquetrum [cuneiform] bone, right wrist, sequela

Summary

This condition represents a displaced fracture of the triquetrum bone in the right wrist, classified as a sequela. The triquetrum is a small carpal bone in the wrist joint, and displacement means the bone fragments are misaligned. A sequela indicates this is a residual effect or complication following the initial injury, such as chronic pain, limited mobility, or deformity. This stage focuses on managing long-term consequences of the fracture.

Causes

The sequela arises from a prior displaced fracture of the triquetrum bone in the right wrist. The original injury was likely caused by trauma, such as a fall onto an outstretched hand, a direct blow, or a twisting injury. The sequela develops as a result of incomplete healing, malunion, or persistent instability from the initial fracture.

Risk Factors

• Inadequate initial treatment or non-compliance with immobilization.
• Underlying conditions like osteoporosis or poor bone healing.
• High-impact activities or repetitive wrist stress that may exacerbate residual issues.
• Previous wrist injuries or fractures that compromise structural integrity.

Symptoms

• Chronic pain or discomfort in the right wrist.
• Persistent swelling or tenderness at the injury site.
• Limited range of motion or stiffness in the wrist or fingers.
• Possible deformity or instability during movement.
• Occasional numbness or tingling if nerve involvement is present.

Diagnosis

Evaluation includes a physical exam to assess wrist function, pain, and deformity. Imaging, such as X-rays or CT scans, may be used to visualize residual displacement or healing. Clinical history of the original fracture and its treatment is critical to confirm the sequela classification.

Treatment Options

• Rehabilitation: Physical therapy to improve strength, flexibility, and function.
• Pain management: Medications or modalities to address chronic discomfort.
• Supportive devices: Braces or splints to stabilize the wrist during activity.
• Surgical intervention: Considered for severe malunion or persistent instability, though less common in sequela stages.

Prognosis and Follow-Up

Prognosis depends on the extent of residual displacement and functional impact. Most patients experience improved symptoms with rehabilitation, but some may have permanent limitations. Regular follow-up with a healthcare provider is recommended to monitor healing and adjust management as needed.

Complications

• Chronic pain or arthritis in the wrist joint.
• Persistent instability or reduced grip strength.
• Nerve compression or vascular issues from malaligned bone fragments.
• Delayed union or nonunion of the original fracture site.

Lifestyle & Prevention

• Avoid high-impact activities that stress the wrist.
• Use ergonomic tools or supports during daily tasks.
• Maintain bone health through proper nutrition and exercise.
• Follow post-injury guidelines to minimize long-term effects.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling occurs, or functional limitations increase. Prompt evaluation is important if numbness, tingling, or color changes in the hand develop, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Document the sequela status clearly, noting the original fracture and its timeline. Ensure the code S62.111S is used only when the condition is a residual effect of a prior displaced triquetrum fracture in the right wrist. Include details on functional impact or chronic symptoms to support the sequela classification.
