S62.026 Nondisplaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist

Name of the Condition

• Nondisplaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist

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. The fracture is nondisplaced, meaning the bone fragments remain in their normal anatomical position. The scaphoid is critical for wrist stability and movement, and fractures in this specific location may result from various injury mechanisms.

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.

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 confirm it is nondisplaced. Additional imaging may be used if clinical suspicion remains despite initial negative results.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone and promote healing.
• Pain management with medications.
• Close monitoring for potential displacement or complications during the healing process.
• Surgical intervention is rarely required for nondisplaced fractures but may be considered if displacement occurs.

Prognosis and Follow-Up

Healing time depends on the severity of the fracture and individual factors, typically ranging from 6 to 12 weeks. Regular follow-up appointments are necessary to monitor healing progress, often with repeat imaging. Full recovery of wrist function is expected with proper immobilization and adherence to treatment plans.

Complications

• Delayed union or nonunion of the fracture, particularly if immobilization is inadequate.
• Avascular necrosis of the scaphoid due to disrupted blood supply.
• Post-traumatic arthritis if the fracture affects joint surfaces.
• Persistent pain or stiffness in the wrist.

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 improving balance and removing tripping hazards at home.
• 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. Consult a healthcare provider if pain persists beyond a few days, worsens, or is accompanied by numbness, tingling, or difficulty moving the wrist.

Tips for Medical Coders

Document the nondisplaced nature of the fracture and specify the middle third of the navicular (scaphoid) bone. Include details about the wrist (unspecified) and any associated injuries or complications. Ensure clinical documentation supports the absence of displacement to justify the use of this code.
