Which procedure is used to immobilize an injured limb with a rigid support?

• A. Splint Application
• B. Casting
• C. Suturing
• D. Cauterization

Answer: (A)

Immobilizing an injured limb is about preventing movement to protect tissues and reduce pain. Using a rigid support to hold the limb still is accomplished by splinting. A splint is placed along the limb and secured with padding and straps to limit motion at and above and below the injury. This allows the area to stabilize and swelling to be managed while avoiding further damage, and it can be applied quickly in the field or ED. Casting, while it also immobilizes, creates a hard shell around the limb and is typically used after initial stabilization and swelling control, making it less suited as the immediate rigid support in acute injury management. Suturing and cauterization address wound closure and bleeding control, not immobilization.
