A system for turning a person from a supine position to a prone position and vice versa includes opposing patient support platens each coupled to a corresponding end of a first and a second COG assembly, the first and second COG assemblies each coupled to a corresponding one of a pair of spindles, each one of the spindles disposed on a corresponding lift column. In yet another embodiment, registration plates, coupled to the system, conveniently align the attachment mechanisms of each COG assembly with distal ends of one or more platens. The registration plates allow for medical staff to align the system so that it straddles the operating table with the attachment mechanisms of the COG assembly in alignment with platen tubes (or other complimentary attachment mechanisms) located at the distal ends of the anterior platen.
