What It Is

The vertebral column (the bones of the spine), the intervertebral discs and the space surrounding the spinal cord can become infected in a number of different ways. The infection might be caused by bacteria or by fungal organisms (Gandhi and Schulder, 2024).

Most spinal infections happen when bacteria or fungi from an infection somewhere else in the body are carried to the spine in the bloodstream. The most common cause is a bacterium called Staphylococcus aureus. Infections can also follow spinal surgery, a urological (bladder or urinary) procedure or recent dental treatment (Gandhi and Schulder, 2024).

Risk factors include conditions that weaken the immune system, such as older age, intravenous drug use, human immunodeficiency virus (HIV), long-term steroid use, diabetes, organ transplant, poor nutrition and cancer (Gandhi and Schulder, 2024).

Surgical risk factors include being in surgery for a long period of time, high blood loss, re-operations at the same site and instrumentation (metal implants such as screws and rods). Infections happen in 1 to 4 percent of surgical cases, despite a number of preventative measures. Most infections after surgery occur between three days and three months following the procedure (Gandhi and Schulder, 2024).

Spinal Infection Anatomy

The spine has a number of blocks that sit on top of each other, known as vertebrae. Each vertebra surrounds the spinal cord, and in between the vertebrae are the intervertebral discs. The discs are there to absorb forces and to allow movement of the spine.

The infection can occur in the disc, around the spinal cord, and in the vertebrae.

Modic changes are something different. They are changes in the bone marrow of a vertebra next to a disc, seen on an MRI scan (type 1 Modic changes show oedema, or swelling). They are not the same as a spinal infection. Antibiotics have been tried for long-term low back pain with Modic changes, but a large trial found that three months of antibiotics gave no meaningful benefit compared with a dummy pill (Bråten et al., 2019).
