Navicular (Scaphoid) Fracture of the Wrist: Injury Awareness and First Aid

A navicular fracture, more commonly known as a scaphoid fracture, involves a break in one of the small carpal bones on the thumb side of the wrist. Among the wrist bones, the navicular bone is the most frequently fractured.

Proper treatment is essential to support healing. Because parts of the navicular bone have a limited blood supply, fractures may heal slowly or incompletely. If not treated appropriately, complications such as chronic pain, stiffness, reduced grip strength, or wrist arthritis may develop.

Common Causes of a Navicular Fracture

Most navicular fractures occur when an individual falls onto an outstretched hand. This mechanism is common in Canada during winter conditions and recreational activities.

Other causes include:

• Severe twisting of the wrist

• Direct impact to the wrist

• Sports such as football, soccer, basketball, or hockey

• Activities such as skateboarding, cycling, or in-line skating

Signs and Symptoms

Navicular fractures can be difficult to recognize because visible deformity is often absent. Symptoms may appear mild at first and worsen over time.

Common signs include:

• Tenderness, pain, or swelling on the thumb side of the wrist
• Pain when gripping, lifting, or twisting the wrist or thumb
• Reduced wrist movement
• Bruising around the wrist

Because these symptoms can resemble a wrist sprain, medical assessment is recommended after any fall onto an outstretched hand.

First Aid Awareness and Early Care

Early first aid focuses on protecting the wrist and limiting movement until medical care is available.

General first aid measures may include:

• Immobilizing the wrist with a splint or sling
• Keeping the wrist elevated to reduce swelling
• Applying cold therapy to manage discomfort
• Avoiding use of the injured hand

Even if initial X-rays appear normal, medical follow-up is important, as navicular fractures may not be immediately visible on imaging.

Medical Management Overview

Treatment depends on fracture severity and alignment and may include:

• Immobilization with a splint or cast (often including the thumb)
• Extended immobilization due to slow healing
• Surgical repair in cases of displacement, poor blood supply, or delayed healing

Recovery time may range from 6 weeks to several months, depending on the injury.

First Aid Training and Injury Recognition

First aid and CPR training, particularly basic, intermediate and advanced first aid, helps individuals:

• Recognize fractures that may appear minor
• Immobilize injuries safely
• Know when urgent medical assessment is required

This knowledge is valuable for athletes, parents, educators, and workers across Canada.
