Cast immobilization is a medical procedure used to support and protect broken bones or injured joints. A cast is typically made from plaster or fiberglass and is applied to keep the affected area stable, allowing it to heal properly. The cast restricts movement, reducing the risk of further injury and ensuring that the bones align correctly during the healing process. The process of applying a cast involves cleaning the skin, padding the area, and wrapping it with the casting material. Once the cast hardens, it provides a rigid structure that can remain in place for several weeks, depending on the severity of the injury. Regular check-ups with a healthcare provider are essential to monitor healing and address any complications.
