There are different varieties of spinal infection that serve to define this back disease:
- Infectious discitis: inflammation of the intervertebral disc, caused by the bacteria E. coli in most cases.
- Spondylodiscitis: In this case, the infection affects the intervertebral disc and vertebrae.
- Ankylosing spondylitis (vertebral osteomyelitis): is a type of arthritis that originates in the bones and joints of the spine. It causes an increase in the volume of these joints, as well as the pelvis and the vertebrae.
- Meningitis: the infection reaches the membranes that are part of the nervous system, and can generate an epidural abscess (accumulation of pus and germs that causes swelling), compressing the spinal cord. Being able to expand to the spinal cord, this pathology can be disabling or fatal in the most extreme cases.
