S62.023 Displaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist

Name of the Condition

• Displaced 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 displaced, meaning the bone fragments have shifted from their normal position. The scaphoid is critical for wrist stability and movement, and fractures in this location may affect function if not properly managed.

Causes

Displaced fractures of the scaphoid typically result from a fall onto an outstretched hand (FOOSH). Direct trauma to the wrist, such as a blow or impact, can also cause this injury. Severe twisting injuries or high-impact activities that stress the wrist may lead to displacement of the bone fragments.

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 determine its characteristics (e.g., displacement, location).

Treatment Options

• Immobilization with a cast or splint to stabilize the bone.
• Pain management with medications.
• Surgical intervention in some cases to realign and stabilize the bone using screws or pins.

Prognosis and Follow-Up

Healing time depends on the severity of the fracture and treatment approach. Follow-up imaging may be required to monitor bone healing. Physical therapy is often recommended to restore wrist function and strength.

Complications

• Delayed union or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Arthritis in the wrist joint due to improper healing.
• Persistent pain or reduced mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Strengthen wrist muscles through targeted exercises.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or inability to move the wrist after an injury. Consult a healthcare provider if symptoms persist or worsen despite initial treatment.

Tips for Medical Coders

Document the specific location (unspecified wrist) and displacement status clearly. Ensure clinical notes support the diagnosis and specify whether the fracture is acute or chronic. Include details about imaging findings or surgical interventions if applicable.
