What is the primary purpose of a splint?

The primary purpose of a splint is to immobilize and protect an injured area. Splints are used to stabilize fractures or dislocations, preventing further movement that could lead to additional injury. By immobilizing the affected limb or joint, splints help to relieve pain, reduce the risk of worsening the injury, and allow for better healing conditions while awaiting further medical evaluation or intervention.

Temporary healing is not the primary function of a splint; rather, it serves as a supportive measure until more definitive treatment is applied. Increasing blood circulation and promoting muscle growth are not functions of a splint; in fact, immobilization can temporarily limit circulation to the area, which is why they are used with caution and for limited time periods.
