In a retrospective study of psoriatic arthropathy and Reiter's disease, it is shown that paravertebral ossification (PVO), of the type described by Bywaters and Dixon (1965) and other types of non-marginal syndesmophytes (McEwan et al., 1971) may be the sole or major radiological abnormality. This sign is of particular value where the appearances of the sacro-iliac or other joints are normal or equivocal and is at least as significant as the peripheral I.P. joint involvement in the hands, where these conditions are suspected. This radiological sign may precede the typical psoriatic rash.
在一项关于银屑病关节炎和赖特综合征的回顾性研究中，结果显示，拜沃特斯和迪克森（1965年）所描述类型的椎旁骨化（PVO）以及其他类型的非边缘性韧带骨赘（麦克尤恩等人，1971年）可能是唯一的或主要的放射学异常表现。在骶髂关节或其他关节表现正常或不明确的情况下，这一征象具有特殊价值，并且在怀疑存在这些病症时，其意义至少与手部外周指间关节受累相当。这种放射学征象可能先于典型的银屑病皮疹出现。
