Splints: Purpose, Uses & First Aid Awareness

A splint is a device used to keep an injured body part still so that it does not move. Splints help protect the area from further harm and can reduce discomfort until proper medical assessment is available. Splints are commonly used for injuries involving bones, joints, or soft tissue.

Relevance in Canadian First Aid & Everyday Activities

Splints may be encountered in sports, recreation, wilderness activities, and workplaces. Knowing what splints do—and what they are not meant to do—helps people respond calmly while waiting for trained responders.

Scenario (Mild & Realistic)

During a school soccer game, Jamie twisted their wrist and had swelling. The coach reminded Jamie not to move the wrist and arranged for a parent to take them for medical assessment. Later, a splint was applied to help protect the wrist during healing.

What a Splint Does

Splints help:

• Limit movement

• Support the injured area

• Protect from further impact

• Maintain comfort until evaluation

Commercial splints are often padded, adjustable, and shaped for different body parts such as wrists, ankles, or fingers.

Common Situations Where Splints Are Used

Splints may be used for:

• Suspected fractures or sprains

• Sports injuries

• Joint injuries

• Certain soft-tissue injuries

• Recovery periods after medical treatment

A health professional decides how a splint is applied and for how long it is used.

Basic First Aid Awareness (Non-Prescriptive)

General first aid awareness emphasizes:

• Keeping the injured part still

• Avoiding forceful movement

• Avoiding attempts to straighten or “fix” a limb

• Using soft padding for comfort

• Allowing trained individuals to apply structured splints

Items like rolled towels, clothing, or commercial splints may provide temporary support, but improvised splints are best handled by trained responders, especially if serious injury is suspected.

Monitoring Without Manipulation

People sometimes observe:

• Sensation (tingling, numbness)

• Swelling

• Colour changes

• Temperature changes
  These observations can be helpful for health professionals during assessment. They should not lead to attempts at home “adjustments” or realignment.

Prevention & Safety Considerations

Splint-related injuries are often linked to:

• Sports collisions

• Falls

• Outdoor activities

• Cycling or skating

• Work involving tools or equipment

Preventive approaches can include:

• Protective equipment (helmets, pads, wrist guards)

• Strength and flexibility training

• Safe play and coaching

• Environmental awareness (ice, loose surfaces, obstacles)

FAQ

What is the difference between a cast and a splint?
A cast is rigid and used longer-term, while a splint provides support and allows some adjustment during early stages or for certain injuries.

Are splints only for broken bones?
No. Splints can also support sprains, joint injuries, and post-treatment recovery.

Can someone splint an injury on their own?
It is generally better for trained responders or health professionals to apply splints, especially if an injury is serious.

Why is movement discouraged?
Movement can increase pain and may worsen the injury, which is why splints help protect the area.
