Reference: Disc osteophyte bars? Reference information: Disc osteophyte complex (also known as disc osteophyte bar) is a term used on MRI of the cervical spine to denote the presence of disc protrusion and/or marginal endplate osteophytes resulting in narrowing of the cervical canal. The term was introduced early in the practice of MRI as distinguishing between disc and osteophyte can be difficult or impossible on T2 weighted images. https://radiopaedia.org/articles/disc-osteophyte-complex#:~:... Osteophytes and Disc Osteophyte Bars Osteophytes are dense outgrowths of bone and are another example of degenerative changes in the spine. They tend to grow from the edges of vertebral bodies where the discs attach to the vertebrae (Fig. 5). When combined with a degenerative intervertebral disc they are known as disc osteophyte bars. They grow backwards towards the spinal cord and nerve roots, and they can also encroach on the interverebral foramen, the channels at sides of the spine through which the nerves enter and leave the spinal canal. They can compress both the spinal cord and nerve roots, causing sciatica and brachialgia, and in severe cases, spinal cord damage. https://www.totalhealth.co.uk/clinical-experts/dr-nigel-kell... -------------------------------------------------- Note added at 16 hrs (2022-12-31 14:49:17 GMT) -------------------------------------------------- For example, upon cutting away a bone spur which is a mixture of calcific and soft tissue along the margins of a disc bar, https://patents.google.com/patent/US4944744 -------------------------------------------------- Note added at 20 hrs (2022-12-31 18:40:15 GMT) -------------------------------------------------- Diagram B on page 51 of the following references shows a disc bar. https://books.google.es/books?id=rqYsBAAAQBAJ&pg=PA51&lpg=PA... |
