A surgical table for prone and lateral positioning of a patient, the table comprising: a base supported on the floor and comprising a head end support structure, a foot end support structure opposite the head end support structure, a rail connecting the head and foot end support structures (106, 108), and a longitudinal axis extending between the head and foot end support structures (106, 108); and a patient support structure comprising an upper body support structure cantilevered off of the head end support structure at a first end and a lower body support structure cantilevered off of the foot end support structure at a second end, the upper body support structure comprising a third end opposite the first end, the lower body support structure comprising a fourth end opposite the second end, the third end and the fourth end being non-joined with each other, the upper body support structure comprising a chest pad, the lower body support structure comprising a lower body translation and rotation structure (294, 298, 292, 296, 155) and at least one pelvic pad (142, 144) supported thereon, the at least one pelvic pad (142, 144) rotationally coupled with the lower body translation and rotation structure (294, 298, 292, 296, 155) via a shaft configured to rotate about a rotation axis that is generally perpendicular to the longitudinal axis, wherein, when the patient support structure changes from a neutral position to a flexed position, the lower body translation and rotation structure (294, 298, 292, 296, 155) is configured to translate the at least one pelvic pad (142, 144) towards the chest pad, and rotate the at least one pelvic pad (142, 144) about the rotation axis, characterised in that the patient support structure further comprises a pair of non-hinged outer frame members (130, 132) supported at a head end by the head end support structure and supported at a foot end by the foot end support structure, the pair of non-hinged outer frame members (130, 132) comprising a right lateral side member and a left lateral side member, wherein the right lateral side member, the left lateral side member, or both are removable from the patient support structure. a base supported on the floor and comprising a head end support structure, a foot end support structure opposite the head end support structure, a rail connecting the head and foot end support structures (106, 108), and a longitudinal axis extending between the head and foot end support structures (106, 108); and a patient support structure comprising an upper body support structure cantilevered off of the head end support structure at a first end and a lower body support structure cantilevered off of the foot end support structure at a second end, the upper body support structure comprising a third end opposite the first end, the lower body support structure comprising a fourth end opposite the second end, the third end and the fourth end being non-joined with each other, the upper body support structure comprising a chest pad, the lower body support structure comprising a lower body translation and rotation structure (294, 298, 292, 296, 155) and at least one pelvic pad (142, 144) supported thereon, the at least one pelvic pad (142, 144) rotationally coupled with the lower body translation and rotation structure (294, 298, 292, 296, 155) via a shaft configured to rotate about a rotation axis that is generally perpendicular to the longitudinal axis, wherein, when the patient support structure changes from a neutral position to a flexed position, the lower body translation and rotation structure (294, 298, 292, 296, 155) is configured to translate the at least one pelvic pad (142, 144) towards the chest pad, and rotate the at least one pelvic pad (142, 144) about the rotation axis, characterised in that the patient support structure further comprises a pair of non-hinged outer frame members (130, 132) supported at a head end by the head end support structure and supported at a foot end by the foot end support structure, the pair of non-hinged outer frame members (130, 132) comprising a right lateral side member and a left lateral side member, wherein the right lateral side member, the left lateral side member, or both are removable from the patient support structure.
