Emergent and nonemergent splinting, bracing, and casting are effective ways to safely remove an injured athlete from the playing field, allow immediate return to play, and permit an athlete to return to play before an injury has completely healed. Sideline providers should be familiar with the materials and resources currently available, and be aware of the sport-specific guidelines regarding their use. Properly applied splints, casts, braces, and padding should function to prevent further injury, promote comfort, and not pose a risk of injury to other participants.
