An apparatus (1,200) for holding a patient during a medical intervention, the apparatus comprising first and second separate end supports (3, 4) and a first and second support for the patient (10, 11, 205, 206) ； wherein each of the first and second end supports is supported by a lower base portion (12, 13) that is operably coupled to the ground and connected to an upper portion (5, 6) attached to the patient support ( 10, 11, 205, 206)； each of the supports for the first and second patient (10, 11, 205, 206) comprises an outer end and an inner end, each of the outer ends of the support for the first and second patient (10, 11, 205 , 206) attached to the upper portion (5, 6) of a respective end support (3, 4) by an angulation subassembly (66, 66 ') such that the supports for the first and second patient (10, 11 , 205, 206) can be selectively articulated with respect to the first and second end supports (3, 4)； the angulation subassemblies (66, 66 ') comprising actuators (112, 112') are operable to cause the selective positioning of said supports for the first and second patient (10, 11) in a plurality of angular orientations with respect to the first and second extreme supports (3, 4)； and the angulation subassemblies (66, 66 ') are movable towards or out of each other during the selective positioning of the support for the first and second patient (10, 11, 205, 206), such that a distance between the outer ends of the support for the first and second patient (10, 11, 205, 206) are shortened or extended respectively to compensate for the angular movement of the supports for the first and second patient (10, 11, 205, 206), while the lower base portions (12, 13) are joined by a rail (2) so that a fixed separation is maintained between the lower base portions (12, 13)； and comprising a compensation sub-assembly (20) a motor (31) that regulates an overall length of the first and second patient support (10, 11, 205, 206) to compensate for the angular movement of the patie
