Fifty posteroanterior hand radiographs from normal adults were reviewed retrospectively to assess the incidence of cortical indistinctness at the base of the proximal phalanges in a normal population. This radiographic change, reported to be an early indicator of rheumatoid arthritis, was seen in at least one site in 10% of the films reviewed. Focal areas of cortical erosion or indistinctness at the bases of the proximal phalanges are not considered to be a reliable sign of early rheumatoid arthritis in the absence of juxtaarticular osteoporosis or changes in the metacarpal heads.
回顾性分析了50例正常成年人的手部后前位X线片，以评估正常人群近端指骨基部皮质模糊的发生率。这种影像学改变据报道是类风湿关节炎的早期指标，在所分析的10%的片子中至少在一个部位可见。在没有关节周围骨质疏松或掌骨头改变的情况下，近端指骨基部的局灶性皮质侵蚀或模糊不被认为是早期类风湿关节炎的可靠征象。
