S62.012B Displaced fracture of distal pole of navicular [scaphoid] bone of left wrist, initial encounter for open fracture

Name of the Condition

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

Summary

A displaced 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 bone fragments shifted out of normal alignment. This open fracture indicates the skin is breached, increasing infection risk. The condition disrupts wrist stability and requires prompt management to address both the fracture and the open wound.

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 events that cause the bone to break and the skin to tear.

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 in the wrist, especially at the base of the thumb.
• Swelling and bruising around the wrist area.
• Decreased range of motion or difficulty gripping objects.
• Visible wound or bleeding if the fracture is open.
• Possible deformity if the fracture is significantly displaced.

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 displacement. Wound assessment to determine the extent of the open injury.

Treatment Options

• Immobilization: Wearing a cast or splint to stabilize the wrist and promote healing.
• Wound Care: Cleaning and dressing the open fracture to prevent infection.
• Surgical Intervention: May be required to realign bone fragments and repair soft tissue.
• Antibiotics: Administered to reduce infection risk in open fractures.
• Pain Management: Medications to alleviate discomfort during recovery.

Prognosis and Follow-Up

Healing depends on fracture severity, treatment adherence, and infection prevention. Immobilization typically lasts several weeks, followed by gradual rehabilitation to restore function. Regular follow-up appointments monitor healing and address complications.

Complications

• Infection at the wound site.
• Nonunion or delayed healing of the fracture.
• Arthritis or long-term wrist stiffness.
• Nerve or blood vessel damage from the injury.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid falls by improving balance and removing tripping hazards.
• Seek prompt medical care for wrist injuries to prevent complications.

When to Seek Professional Help

• Severe pain, swelling, or deformity in the wrist.
• Visible wound or bleeding from the wrist.
• Numbness, tingling, or loss of circulation in the hand.
• Inability to move the wrist or grip objects.

Tips for Medical Coders

Document the fracture type (displaced), bone involved (distal pole of navicular [scaphoid]), laterality (left wrist), encounter type (initial), and wound status (open). Include details on trauma mechanism, imaging results, and treatment provided to support code assignment. Ensure open fracture documentation specifies the wound’s characteristics for accurate coding.
