S62.01 Fracture of distal pole of navicular [scaphoid] bone of wrist

Name of the Condition

• Fracture of distal pole of navicular [scaphoid] bone of wrist

Summary

A fracture of the distal pole of the navicular (scaphoid) bone involves a break in the lower portion of this small, critical wrist bone. This type of fracture may result from trauma and requires evaluation to determine appropriate management, as the scaphoid plays a key role in wrist stability and movement.

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.

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 allow the bone to heal.
• Pain management: Medications to reduce discomfort and inflammation.
• Surgical intervention: May be required for displaced fractures or those that fail to heal with immobilization.

Prognosis and Follow-Up

Healing time depends on fracture severity and treatment. Immobilization typically lasts 6–12 weeks, with follow-up imaging to monitor progress. Physical therapy may be needed to restore strength and mobility. Most fractures heal well with proper care, but delayed healing or nonunion can occur.

Complications

• Delayed union or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Arthritis in the wrist joint over time.
• Nerve or tendon damage from the injury or treatment.

Lifestyle & Prevention

• Use wrist guards during high-risk activities like sports or falls.
• Maintain bone health through proper nutrition and exercise.
• Avoid repetitive wrist stress or improper techniques that increase injury risk.

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 after initial treatment also warrants medical evaluation.

Tips for Medical Coders

Document the specific location (distal pole) and any associated details, such as displacement or treatment, to ensure accurate coding. Note the clinical context, including trauma mechanism and diagnostic findings, to support code assignment.
