A patient positioner for maintaining a patients position during a medical procedure including a body anchoring portion placeable atop an operating table, chest straps, support base straps, upper arm straps, wrist straps, a substrate backing substantially concentrically disposed on and fixedly attached to the body anchoring portion. In use, the body anchoring portion is positioned under the patients torso with a portion of the substrate backing wrapped over each of the patients arms while the chest straps are brought over the patients shoulders and criss-crossed over the patients chest and secured on an opposing side rail. The upper arm and wrist straps are brought from underneath the patients torso and wrapped over the patients arms. The support base straps are placed through a break of the operating table and brought around the support base and secured to each other to prevent the patient from sliding in the Trendelenburg position.
