Thanks for writing this article. Although I am not an expert, I have some experience working with cases of discitis amongst patients. I am currently an undergraduate student, and I intern with a brain and spinal surgeon.
The surgeon I work under has had to deal with cases of discitis in adults. I recently read somewhere that one to two percent of patients who undergo spinal surgery develop an infection that causes discitis. Although this may seem like a small number, the surgeon I work for deals with this infection at least a few times a year.
The patient usually comes back into the office after complaining about back issues. A MRI or a CT scan can diagnose discitis, but a blood test is taken to insure that there is an infection.
I have learned a lot about the spine through studying discitis and other spinal conditions. The spine is a very resilient organ of the body. But when it is compromised, it literally affects the foundation and integrity of a patient.
