This is a device or apparatus for measuring and observing sagittal angles (planes) of the spine in radio-diagnosis rooms by allowing its display in radiographic studies of the sagittal spine. It basically comprises legs 4 which can be adjusted in terms of height and coupled to a base 3 from which a tubular column 1 emerges to which is coupled a support 5 which can be moved along it, a vertical, graduated lead rule 6 being connected to the support, and independent pieces 10 running via said rule which are provided with individual channels via which horizontal, graduated leaded rules 12 move, via which the various angles of the spinal column are measured. Not only the rules but also the independent pieces and the support all have a means of immobilization. <IMAGE>
