S62.013S Displaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, sequela

Name of the Condition

• Displaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, sequela

Summary

A displaced fracture of the distal pole of the navicular (scaphoid) bone in the unspecified wrist, sequela, refers to a healed or healing fracture with residual effects. This condition involves a prior break in the lower portion of the scaphoid bone, where fragments were shifted out of alignment, and now presents with ongoing consequences such as limited mobility, pain, or structural changes. The scaphoid’s role in wrist stability means sequela may impact function even after initial healing.

Causes

This sequela arises from a previous displaced fracture of the distal pole of the navicular bone, typically caused by trauma like a fall onto an outstretched hand (FOOSH), direct wrist impact, or twisting injuries. The initial fracture displaced bone fragments, and the sequela reflects incomplete resolution or lasting effects of that injury.

Risk Factors

• Prior wrist trauma or fractures, especially involving the scaphoid.
• Inadequate initial treatment or healing of the original fracture.
• Activities or conditions that stress the wrist, such as repetitive motion or osteoporosis, which may exacerbate residual effects.

Symptoms

• Chronic wrist pain, particularly near the base of the thumb.
• Reduced range of motion or stiffness in the wrist.
• Persistent swelling or deformity.
• Grip weakness or difficulty with fine motor tasks.
• Possible arthritis or joint instability in the long term.

Diagnosis

Evaluation includes a physical exam to assess wrist function, pain, and deformity. Imaging, such as X-rays or MRI, may be used to identify residual displacement, arthritis, or other structural changes. Clinical history of the original fracture is critical to confirm the sequela.

Treatment Options

Management focuses on symptom relief and functional improvement. Options may include physical therapy to restore mobility, pain management, or orthotic devices. In severe cases, surgery to address residual displacement or arthritis might be considered, though this depends on the extent of sequela.

Prognosis and Follow-Up

Prognosis varies based on the severity of residual effects. Many patients experience improved function with therapy, but some may have lasting limitations. Regular follow-up with a healthcare provider is important to monitor for complications like arthritis or nerve issues.

Complications

• Chronic pain or stiffness.
• Post-traumatic arthritis in the wrist.
• Nerve compression or vascular issues.
• Reduced grip strength or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities that stress the wrist.
• Use ergonomic tools or supports during repetitive tasks.
• Maintain bone health through diet and exercise to reduce fracture risk.
• Follow rehabilitation guidelines after injury to minimize sequela.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling occurs, or functional limitations impact daily activities. Prompt evaluation is important if numbness, tingling, or signs of infection (e.g., redness, fever) develop.

Tips for Medical Coders

This code is for a sequela of a displaced distal pole navicular fracture. Document the residual effects (e.g., chronic pain, limited mobility) and confirm the prior fracture history. Ensure the encounter aligns with the sequela phase, not the acute injury.
