Cervical vertebral columns (214) of adult human skeletons belonging to South African blacks and whites were examined for the presence of osteophytes. It was found that the cervical vertebrae of the black samples were significantly less affected by degenerative changes than in the whites. This finding has specific clinical implications in that the distribution of osteophytosis in the blacks also follows a different pattern than in the whites; osteophytes appear to affect either the vertebral body or apophysial joint facets in the cervical vertebrae of the blacks. In the whites, in sharp contrast, both sites are often affected on the same vertebra, which in life may result in a pincer-like entrapment of the spinal nerve root and/or vertebral artery. Consideration is given to the possible physiological and/or functional causes of the differences in distribution and pattern of development of osteophytes in the cervical spines of the two population groups.
对属于南非黑人和白人的成年人体骨骼的颈椎柱（214个）进行了骨赘检查。结果发现，黑人样本的颈椎受退行性变的影响明显小于白人。这一发现具有特定的临床意义，因为黑人中骨赘形成的分布模式也与白人不同；在黑人的颈椎中，骨赘似乎只影响椎体或关节突关节面。相比之下，在白人中，同一椎体的这两个部位常常都受到影响，在实际生活中这可能导致钳夹样压迫脊神经根和/或椎动脉。文中还考虑了这两个人群组颈椎中骨赘分布和发展模式差异的可能生理和/或功能原因。
