S62.032A Displaced fracture of proximal third of navicular [scaphoid] bone of left wrist, initial encounter for closed fracture

Name of the Condition

Displaced fracture of proximal third of navicular [scaphoid] bone of left wrist, initial encounter for closed fracture

Summary

A displaced fracture of the proximal third of the navicular (scaphoid) bone in the left wrist is a break where the bone fragments have shifted out of their normal alignment. This type of fracture typically results from trauma and requires prompt medical attention to ensure proper healing and restore wrist function. The proximal third of the scaphoid is a critical area for wrist stability, and displacement can affect joint mechanics if not properly managed.

Causes

Direct trauma to the wrist, such as a fall onto an outstretched hand, is the most common cause. High-impact activities or accidents, including sports injuries or motor vehicle collisions, can also lead to this type of fracture. The force applied to the wrist during such events often targets the scaphoid bone due to its position in the wrist joint.

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.

Symptoms

• Intense pain and swelling in the wrist, particularly on the thumb side.
• Visible deformity or misalignment of the wrist.
• Difficulty moving the wrist or gripping objects.
• Bruising or tenderness over the scaphoid bone area.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, are used to confirm the fracture and evaluate displacement. Additional tests may be used to check for nerve or ligament damage.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone.
• Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics.
• Surgical intervention may be required for severe displacement to realign and fix the bone fragments.

Prognosis and Follow-Up

With proper treatment, most displaced fractures of the proximal third of the scaphoid bone heal within 6 to 12 weeks. Follow-up imaging is typically performed to monitor healing progress. Long-term outcomes depend on the severity of the fracture and adherence to treatment plans. Physical therapy may be recommended to restore strength and range of motion.

Complications

• Nonunion or delayed healing of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Arthritis in the wrist joint due to improper alignment.
• Nerve or tendon damage from the injury or treatment.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as wrist guards in sports.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid falls by using assistive devices if balance is impaired.
• Strengthen wrist muscles through targeted exercises to improve 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 by a healthcare provider.

Tips for Medical Coders

Document the specific location (proximal third of the navicular bone), laterality (left wrist), and encounter type (initial for closed fracture) to accurately assign this code. Ensure clinical documentation supports the displacement and closed nature of the fracture. Note any associated injuries or complications that may require additional coding.
