| pubmed-article:3340781 | pubmed:abstractText | Previous reports have emphasized two types of osteophytes on the anterior aspects of the lumbar vertebral bodies: the common claw osteophyte and the less common but more significant traction osteophyte, which is indicative of spinal instability. To delineate the importance of the traction osteophyte, a radiographic-pathologic study was conducted. The results indicate that claw osteophytes are more frequent than traction osteophytes, that both may coexist in a single vertebral body, and that, in most cases, these osteophytes appear to represent different stages of the same pathologic process. | lld:pubmed |
