What are changes to the ligament and tendon attachments to bone, whether its inflammatory, degenerative, or metabolic?

Syndesmophyte

Marginal

What type of enthesophyte appears to come right off the edge of the vertebral body endplate?

Nonmarginal

What type of enthesophyte appears to come off the vertebral body slightly above or below the vertebral body endplate?

FALSE

-- EITHER marginal or nonmarginal

(NOTE: syndesmophyte = inflammatory)

T/F: Inflammatory arthritis may have either or both marginal or nonmarginal syndesmophytes

TRUE

-- either OR both marginal/nonmarginal

(NOTE: osteophyte = degenerative)
