               1. A method of manipulating a patient before, during, or after surgery using a patient-positioning system, the method comprising: 
            providing a first vertical support portion at a first end of the patient-positioning system, a second vertical support portion at a second end of the patient-positioning system, a first cantilevered support portion moveably supported by the first vertical support portion adjacent the first end, and a second cantilevered support portion moveably supported by the second vertical support portion adjacent the second end, 
                the second cantilevered support portion including a base portion, a first end portion, and a first side portion, the first end portion and the first side portion being attached to one another, the first end portion and the first side portion pivotally attached relative to the base portion, and the base portion being moveably attached to the second vertical support portion; 
                supporting a head-support portion and a thorax-support portion by the first cantilevered support portion, and supporting an upper-leg support portion and a lower-leg support portion by the first side portion of the second cantilevered support portion; 
                supporting a head portion of the patient on the head-support portion, a thorax portion of the patient on the thorax-support portion, upper leg portions of the patient on the upper-leg support portion, and lower leg portions of the patient on the lower-leg support portion; 
                adjusting relative positions of the first cantilevered support portion and the second cantilevered support portion to correspondingly twist an upper body portion and a lower body portion of the patient relative to one another by rotatably adjusting the first cantilevered support portion relative to the first vertical support portion in a first direction, and rotatably adjusting the second cantilevered support relative to the second vertical support portion in an opposite second direction; and 
                moving the upper-leg support portion and the lower-leg support via pivotal movement of the first side portion and the first end portion relative to the base portion of the second cantilevered support portion.
