S62.015B Nondisplaced fracture of distal pole of navicular [scaphoid] bone of left wrist, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of distal pole of navicular [scaphoid] bone of left wrist, initial encounter for open fracture

Summary

A nondisplaced fracture of the distal pole of the navicular (scaphoid) bone in the left wrist involves a break in the small bone near the base of the thumb, with the bone fragments remaining in their normal alignment. This type of fracture is classified as open, meaning the skin over the fracture site is broken, and requires prompt medical evaluation to prevent infection and ensure proper healing.

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 that breaks the skin and fractures the bone.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Inadequate wrist protection or improper technique in sports.
• Osteoporosis or weakened bone structure 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.
• Visible wound or break in the skin over the fracture site.
• Possible numbness or tingling if nerves are affected.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility, including evaluation of the open wound. Imaging tests, such as X-rays, CT scans, or MRI, to visualize the fracture and confirm nondisplacement. Assessment of the wound for contamination or infection risk.

Treatment Options

• Wound Care: Cleaning and dressing the open fracture to prevent infection.
• Immobilization: Wearing a cast or splint for several weeks to allow the bone to heal.
• Antibiotics: Administered to reduce the risk of infection due to the open nature of the fracture.
• Surgical Intervention: May be required if the wound is severe or if there is significant contamination.
• Physiotherapy: Strengthening and rehabilitation exercises after immobilization to restore function.

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment, though open fractures carry a higher risk of infection. Follow-up appointments are necessary to monitor healing, assess for complications, and adjust treatment as needed. Full recovery may take several weeks to months, depending on the severity of the fracture and wound.

Complications

• Infection at the fracture site.
• Delayed healing or nonunion of the bone.
• Arthritis in the wrist joint over time.
• Nerve or blood vessel damage due to the fracture or associated trauma.

Lifestyle & Prevention

• Use protective gear, such as wrist guards, during high-risk activities.
• Maintain bone health through proper nutrition and exercise to reduce fracture risk.
• Practice safe techniques in sports or activities to minimize falls and impacts.
• Seek prompt medical attention for wrist injuries to prevent complications.

When to Seek Professional Help

• If there is severe pain, swelling, or deformity in the wrist.
• If the skin over the wrist is broken or there is visible bleeding.
• If there is numbness, tingling, or loss of function in the hand or fingers.
• If symptoms worsen or do not improve with initial care.

Tips for Medical Coders

Document the open nature of the fracture, including details of the wound (e.g., size, contamination, treatment). Specify the left wrist and the initial encounter. Ensure documentation supports the nondisplaced status of the fracture and the anatomical location (distal pole of the navicular [scaphoid] bone).
