Alternate Names : Disk inflammation
Definition
Diskitis is swelling (inflammation) and irritation of the space between the bones of the spine (intervertebral disk space).
Overview, Causes, & Risk Factors
Diskitis is an uncommon condition. It is usually seen in children younger than age 10.
Diskitis can be caused by a bacterial or viral infection. Or it can be caused by other inflammation, such as from autoimmune diseases (conditions in which the immune system mistakenly attacks certain cells in the body). The upper back (thoracic) and low back (lumbar) disks are most commonly affected.
Diskitis can also be confused with problems related to hip pain.

Skeletal spine
The spine is divided into several sections. The cervical vertebrae make up the neck. The thoracic vertebrae comprise the chest section and have ribs attached. The lumbar vertebrae are the remaining vertebrae below the last thoracic bone and the top of the sacrum. The sacral vertebrae are caged within the bones of the pelvis, and the coccyx represents the terminal vertebrae or vestigial tail.
Intervertebral disk
The vertebral column is made up of 26 bones that provide axial support to the trunk. The vertebral column provides protection to the spinal cord that runs through its central cavity. Between each vertebra is an intervertebral disk. The disks are filled with a gelatinous substance, called the nucleus pulposus, which provides cushioning to the spinal column. The annulus fibrosus is a fibrocartilaginous ring that surrounds the nucleus pulposus, which keeps the nucleus pulposus in tact when forces are applied to the spinal column. The intervertebral disks allow the vertebral column to be flexible and act as shock absorbers during everyday activities such as walking, running and jumping.
