Moderate to severe spinal stenosis at the levels of L3/4 and L4/5 [further explanation needed] The diagnosis of spinal stenosis involves a complete evaluation of the spine. The process usually begins with a medical history and physical examination. X-ray and MRI scans are typically used to determine the extent and location of the nerve compression.
A research group led by Gilligan has presented a description of how they hypothesize 4 stages, from infection of the discus to developing Modic changes in the vertebrae. [ 57 ] The first study to investigate the efficacy of long-term antibiotic treatment for patients with Modic changes was published in 2013. [ 58 ]
