The RISE™ (Rigid Immobilization System for Extremities) is a rugged, low-profile, splint for extremity fractures and pelvic binding in the prehospital environment. Born from lessons on the battlefield, it can be intuitively applied under stress to create a straight splint, 90-degree splint, or pelvic binder. It can be easily secured to the patient with items such as an elastic wrap or pressure bandage.
