Fiberglass casts are lightweight, durable coverings used to immobilize broken bones or injured limbs. Made from a combination of fiberglass and resin, they harden quickly when applied, providing strong support while allowing for some breathability. Unlike traditional plaster casts, fiberglass casts are water-resistant, making them easier to manage in daily activities. These casts come in various colors and designs, allowing for personalization. They are typically applied by a medical professional, who ensures a proper fit to promote healing. Patients can usually resume normal activities, with some precautions, while wearing a fiberglass cast during their recovery period.
