The primary purpose of using splints in emergency care is to immobilize and protect injured limbs. When a fracture or serious injury occurs, movement of the affected area can exacerbate the damage, cause severe pain, or lead to further complications such as nerve or vascular injury.

By immobilizing the limb, splints help maintain the alignment of bones and joints, preventing any unnecessary movement that could worsen the injury. This immobilization is crucial for the healing process, as it allows for proper stabilization until the patient can receive further medical treatment, such as X-rays or surgical intervention.

While splints may provide some degree of comfort by stabilizing a painful injury, their primary function is centered on immobilization and protection. They do not enhance blood flow or correct dislocations directly; rather, their role is to ensure stability and minimize additional harm to the injured area.
