sclerotic

1. hard; firm; indurated; applied especially in anatomy to the firm outer coat of the eyeball, which is often cartilaginous and sometimes bony.

Adj. 1. sclerotic - relating to or having sclerosis; hardened

I can't recall what "endplate sclerotic changes" means, though; someone had kindly told me what it means in the past - after it also turned up in reports about my spinal films.
