S62.014 Nondisplaced fracture of distal pole of navicular [scaphoid] bone of right wrist

Name of the Condition

• Nondisplaced fracture of distal pole of navicular [scaphoid] bone of right wrist

Summary

A nondisplaced fracture of the distal pole of the navicular (scaphoid) bone in the right wrist involves a break in the lower portion of this small, critical wrist bone where the bone fragments remain in their normal alignment. This type of fracture typically results from trauma and requires evaluation to determine appropriate management, as the scaphoid plays a key role in wrist stability and movement.

Causes

Typically results from a fall onto an outstretched hand (FOOSH). Can also occur due to direct trauma to the wrist, such as a blow or impact. May involve twisting injuries or high-force activities that stress the wrist.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, particularly in older adults.
• Previous wrist injuries or fractures that may compromise bone integrity.

Symptoms

• Pain and tenderness localized to the wrist, especially near the base of the thumb.
• Swelling and bruising around the wrist area.
• Decreased range of motion or difficulty gripping objects.
• Possible numbness or tingling if nerves are affected.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to visualize the fracture and determine displacement or specific location.

Treatment Options

• Immobilization: Wearing a cast or splint for several weeks to allow healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Follow-up imaging: Monitoring with repeat X-rays to ensure proper healing.
• Surgical intervention: Rarely required for nondisplaced fractures but may be considered if healing is delayed or complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures of the distal pole of the scaphoid heal well with immobilization and conservative management. Follow-up care is important to monitor for complications, such as nonunion or avascular necrosis, which can occur due to the bone's limited blood supply. Rehabilitation may be needed to restore full wrist function.

Complications

• Delayed union or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Post-traumatic arthritis in the wrist.
• Persistent pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Strengthen wrist muscles through targeted exercises.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or deformity after an injury. Consult a healthcare provider if pain persists, worsens, or if you notice numbness, tingling, or difficulty moving the wrist.

Tips for Medical Coders

Document the specific location (distal pole of navicular [scaphoid] bone) and laterality (right wrist) to accurately assign this code. Ensure clinical documentation confirms the fracture is nondisplaced, as this distinguishes it from displaced fractures. Include details of the injury mechanism and any imaging findings to support the diagnosis.
