S62.013A Displaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Name of the Condition

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

Summary

A displaced fracture of the distal pole of the navicular (scaphoid) bone in the unspecified wrist involves a break in the lower portion of this small, critical wrist bone, with the bone fragments shifted out of their normal alignment. This type of fracture can disrupt wrist stability and may require specific management to ensure proper healing, particularly since the scaphoid plays a key role in wrist function.

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.
• Possible deformity if the fracture is significantly displaced.

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 stabilize the wrist and promote healing.
• Surgical intervention: May be required if the fracture is severely displaced or unstable, involving fixation with pins, screws, or other devices.
• Pain management: Medications to alleviate discomfort during the healing process.
• Rehabilitation: Physical therapy to restore strength and range of motion once healing allows.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, treatment adherence, and individual healing capacity. Most fractures heal with proper immobilization, but displaced fractures may require longer recovery or surgery. Follow-up appointments are essential to monitor healing, typically with repeat imaging to confirm bone union and assess for complications.

Complications

• Nonunion or delayed healing, particularly if the fracture is not properly immobilized.
• Avascular necrosis, where the bone tissue dies due to disrupted blood supply.
• Arthritis or chronic pain in the wrist over time.
• Nerve or tendon damage from the initial injury or surgical intervention.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as wrist guards in sports.
• Maintain bone health through adequate calcium and vitamin D intake, especially in older adults.
• Avoid falls by improving balance and using assistive devices if needed.
• Strengthen wrist muscles through targeted exercises to enhance stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or deformity after an injury. Persistent pain, numbness, or difficulty moving the wrist after initial treatment also warrants evaluation to rule out complications.

Tips for Medical Coders

Document the specific wrist (unspecified) and confirm the fracture is closed and displaced. Note the initial encounter status, as this impacts code assignment. Ensure clinical documentation supports the displacement and closed nature of the fracture to align with the code's requirements.
