Spondylodiscitis affects which part of the spine first in children?

In children, the intervertebral disc is the first structure hit by infection because the disc has blood supply during growth, allowing bacteria traveling through the bloodstream to seed the disc space. This makes discitis the initial lesion, with the infection then spreading to the adjacent vertebral endplates (and sometimes the vertebral bodies) as it progresses. The posterior elements and spinous processes are less likely to be involved first due to their separate vascular patterns, so they aren’t the initial site of spondylodiscitis in kids. In adults, the pattern can differ since the disc is relatively avascular, and endplates are often the starting point instead.
