What does a splint primarily do?

A splint primarily serves to immobilize an injured extremity, which is critical for preventing further injury and aiding in the healing process. By restricting movement, a splint helps to stabilize fractures or dislocations, reducing the risk of additional damage to surrounding tissues, muscles, and nerves. This immobilization is essential not only for the safety of the patient, but also for facilitating subsequent medical assessment and treatment. While a splint may incidentally provide some level of support and comfort, its main function is to ensure that the injured area remains as still as possible until appropriate medical care can be administered.
