Slipped disc. Coloured 3D computed tomography (CT) scan showing a side (sagittal) view of the lower part of the backbone (green) in a patient with a slipped disc. The front of the body is at left. The spine consists of a column of small bones (vertebrae, square blocks) separated and cushioned by soft intervertebral discs (thinner areas). A slipped disc is an intervertebral disc that has ruptured (here the one just below centre). The internal disc material is squeezed out (to the right here) and often puts pressure on the spinal cord (red), causing severe pain. The rest of the spine is at right (white). Surgery may be needed, though most slipped discs heal with rest.
