Fiberglass is a composite material used in casting for lightweight properties; which population is specifically noted?

• A. General population
• B. Children and elderly
• C. Professional athletes
• D. Infants

Answer: (B)

Fiberglass casts are lightweight, durable, and quick-drying, which makes immobilization more comfortable and easier to manage. This is especially beneficial for children and the elderly, who often have smaller limbs, skin sensitivity, or a higher risk of complications from heavier, bulkier plaster casts. The lighter weight reduces strain on joints and improves tolerance during wear, while faster drying speeds up the immobilization process and makes skin checks and hygiene easier—both important considerations for these populations. For these reasons, the material is specifically noted for use in children and elderly.
