S62.024B Nondisplaced fracture of middle third of navicular [scaphoid] bone of right wrist, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of middle third of navicular [scaphoid] bone of right wrist, initial encounter for open fracture

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, on the right side. The fracture is nondisplaced, meaning the bone fragments remain in their normal position. It is an open fracture, indicating the bone has pierced the skin, and this is the initial encounter for treatment.

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.
• Visible wound or open skin at the fracture site (due to the open fracture nature).

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., nondisplacement, location). Assessment of the open wound to evaluate contamination or infection risk.

Treatment Options

• Immediate wound care to clean and dress the open fracture site.
• Immobilization with a cast or splint to stabilize the bone.
• Pain management with medications.
• Surgical intervention may be required to clean the wound, realign the bone, or stabilize with hardware.
• Antibiotics to prevent infection due to the open nature of the fracture.

Prognosis and Follow-Up

Healing time depends on the severity of the fracture and the success of treatment. Nondisplaced fractures generally heal well with proper immobilization. Follow-up imaging may be needed to confirm healing. Physical therapy may be recommended to restore wrist function.

Complications

• Infection at the open wound site.
• Delayed healing or nonunion of the fracture.
• Arthritis in the wrist due to joint damage.
• Nerve or blood vessel injury affecting wrist function.
• Chronic pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., wrist guards in sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Practice proper wrist positioning during activities to reduce stress.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or an open wound after an injury. Contact a healthcare provider if symptoms worsen, or if you notice signs of infection (e.g., redness, pus, fever).

Tips for Medical Coders

Document the fracture location (middle third of navicular bone), laterality (right wrist), and fracture type (nondisplaced, open). Note the initial encounter for treatment and any associated wound details. Ensure documentation supports the open fracture classification and the absence of displacement.
