Splint Care and Injury Support: First Aid Guidance for Canadians

A splint is used to protect and stabilize a fracture, sprain, or other musculoskeletal injury by limiting movement and reducing pain while healing begins. In Canada, splinting is a core skill taught in Basic, Intermediate, and Advanced First Aid courses, particularly for workplace safety, outdoor response, and emergency preparedness.

If a removable splint is prescribed, it is essential to follow the healthcare provider’s instructions carefully. The splint should only be removed or adjusted if explicitly advised.

Most splints are adjustable. Many are pre-made using fiberglass or plaster, while others include built-in padding or inflatable air chambers to secure the injured area comfortably. Your healthcare provider will explain when and how adjustments should be made.

Weight-Bearing and Mobility

Avoid placing weight on a splinted limb unless you have been told it is safe to do so. If a walking boot or lower-limb splint is used, the doctor will clearly indicate when partial or full weight-bearing is allowed.

Improper weight-bearing can delay healing and increase the risk of complications.

Managing Swelling Safely

It is common for a splint to feel tight during the first few days after an injury or surgical procedure due to swelling. However, excessive swelling inside a splint can be dangerous, as it may restrict circulation and damage nerves.

How to Reduce Swelling

• Elevate the injured arm or leg on pillows so it remains above heart level, if possible
• Apply an ice pack for 10–20 minutes at a time, every 1–2 hours for the first 2–3 days
• Ensure the splint stays completely dry during icing
• If fingers or toes are not injured, gently wiggle them periodically to promote circulation
• Over-the-counter NSAIDs (such as ibuprofen) may help reduce pain and swelling if appropriate—always follow label instructions or medical advice

Keeping the Splint Dry

Moisture under a splint can cause skin irritation, breakdown, and infection.

• Cover the splint with a waterproof barrier when bathing or showering
• If the splint is removable, pat the skin completely dry before reapplying
• Never submerge a splint in water unless instructed by a healthcare provider

Skin Care and Comfort

Proper skin care helps prevent complications while wearing a splint.

• Ensure skin is clean and dry before reapplying a removable splint
• If the splint cannot be removed, use cool air from a fan or hair dryer (on a cool setting) to relieve itching
• Never insert objects under the splint to scratch the skin
• Avoid lotions, creams, or oils near splint edges
• If redness or soreness develops at the edges, add soft padding and monitor closely

First Aid Training Context (Canada)

Splint care and injury stabilization are essential components of Canadian first aid education, including:

• Basic First Aid – recognizing injuries and providing initial immobilization

• Intermediate First Aid – splinting fractures and managing swelling

• Advanced First Aid – complex injury management, prolonged care, and monitoring circulation

These skills are especially important in workplaces, outdoor recreation, industrial settings, and remote environments across Canada.

Improper splint use can lead to circulation problems, nerve injury, or delayed healing. Anyone with increasing pain, numbness, discoloration, or swelling should seek medical care immediately.

To learn proper splinting techniques, injury assessment, and ongoing care, Canadians are encouraged to complete a certified first aid and CPR course appropriate to their work or lifestyle needs.
