Splint - Definition

Ask a question


A splint is a rigid structure, generally made of plastic, sometimes inflatable, which allows one part of the body to be immobilized, often used following trauma with suspicion of a fracture. When used in emergency care, a splint performs two functions of both pain-relieving, as it relieves pain caused by moving the body part, and also preventing a potential bone displacement if there is truly a fracture. X-ray imaging or other technique can also confirm or rule out the existence of a fracture. A splint can also be used to immobilize a joint in cases of sprain or dislocation. It can be left in place over several days, even weeks, for as long as it takes the condition to heal.
