S62.02 Fracture of middle third of navicular [scaphoid] bone of wrist

Name of the Condition

• Fracture of middle third of navicular [scaphoid] bone of wrist

Summary

This condition involves a break in the middle third of the navicular (scaphoid) bone, a small bone in the wrist near the base of the thumb. The scaphoid is critical for wrist stability and movement. Fractures in this specific location may or may not involve displacement of bone fragments, depending on the injury mechanism.

Causes

Typically results from a fall onto an outstretched hand (FOOSH). Can occur due to direct trauma to the wrist, such as a blow or impact. May also result from twisting injuries or high-impact 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 have compromised bone integrity.

Symptoms

• Pain and tenderness at the base of the thumb.
• Swelling and bruising around the wrist area.
• Limited wrist movement 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 its characteristics (e.g., displacement, location).

Treatment Options

• Immobilization: Wearing a cast or splint for several weeks to allow healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Surgical intervention: May be required for displaced fractures to realign and stabilize the bone.

Prognosis and Follow-Up

Most fractures heal with proper immobilization, but healing time can vary. Follow-up imaging may be needed to confirm union. Complications like nonunion or arthritis are possible, especially if treatment is delayed.

Complications

• Nonunion (failure of the bone to heal).
• Avascular necrosis (loss of blood supply to the bone).
• Post-traumatic arthritis in the wrist joint.
• Persistent pain or limited mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, cycling).
• Strengthen wrist muscles to improve stability.
• Avoid falls by maintaining balance and using assistive devices if needed.

When to Seek Professional Help

Seek immediate care if you experience severe wrist pain, swelling, or deformity after an injury. Persistent pain, numbness, or difficulty moving the wrist also warrants evaluation.

Tips for Medical Coders

Document the fracture location (middle third of the navicular bone) and any associated details (e.g., displacement, open/closed status) to ensure accurate coding. Verify clinical documentation aligns with the specific ICD-10-CM code S62.02.
