Updates to Article Attributes

was changed:
Cervical degenerative changes can be graded using a very old but reliable classification given by Kellgren et al. It is based on findings on a lateral cervical spine radiograph although it can also be applied to MRI evaluation of spine.
The key parameters are osteophyte formation, intervertebral disc height narrowing and vertebral end-plate sclerosis.
-
grade 0 (normal)
- no degenerative changes
-
grade 1 (minimal/early)
- minimal anterior osteophyte formation
- no reduction of intervertebral disc height
- no vertebral endplate sclerosis
-
grade 2 (mild)
- definite anterior osteophyte formation
- subtle or no reduction in Intervertebral disc height (<25%)
- just recognisable sclerosis of the endplates
-
grade 3 (moderate)
- definite anterior osteophyte formation
- moderate narrowing of the disc space (25-75%)
- definite sclerosis of the endplates and osteophyte sclerosis
-
grade 4 (gross)
- large and multiple large osteophyte formation is seen
- severe narrowing of the disc space (>75%)
- sclerosis of the endplates with irregularities
