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.
常见的爪形骨赘和不太常见但更具意义的牵引性骨赘，后者提示脊柱不稳定。为了阐明牵引性骨赘的重要性，进行了一项影像学-病理学研究。结果表明，爪形骨赘比牵引性骨赘更常见，两者可能在单个椎体中同时存在，并且在大多数情况下，这些骨赘似乎代表了同一病理过程的不同阶段。
