Severity Grade of Spondylodiscitis Described by Pee etal.¹⁰⁾

Grade	Definition
I	Isolated discitis or discitis with minor destruction of the endplate
II	Discitis with moderate endplate destruction
III	Discitis with destruction of the vertebral body

The differentiation between “minor” and “moderate” destruction to the endplate is based on findings of the destruction of the vertebral body adjacent to the endplate noted on computed tomography scans. Destruction of the posterior or anterior wall of the vertebral body is defined as grade III.
