【摘要】 本文分析湖南长沙地区临床诊断为佝偻病的510例3岁以下婴幼儿双腕,左膝及踝的X 线正位照片,有360例出现 X 线改变,早期为292例(57.3%),表现为临时钙化带一部分或全部模糊,凸凹不平,变薄与密度减低。最早改变出现在尺骨远端的内侧和/或外侧角。对34例正常3岁以下婴幼儿的管状骨进行了骺线宽度的测量,并提出股骨远端骺线测量应以髁间区为定点最为可靠。作者根据病例分析资料,初步拟出一个佝偻痛 X 线分期标准,供参考。更多还原

【Abstract】 510 cases of Rickets clinically diagnosed below 3 were studied in Changsha ofHunan province.They were given X-ray examination of both wrists,left knee andleft ankle in antero-posterior view respectively.The data were analysed as follow.360 cases showed roentgen appearance of rickets,among which 292(57.3%)were inthe early stage,63(12.3%)in the healing stage,and 5(1%)showed moderatechanges.In the case of the early stage,the provisional zone of calcification manifestedpartial or complete blurring,irregular wavy appearance;thinning;and decrease ofdensity.As the disease was progressive,the provisional zone of calcification graduallydisappeared and showed typical cupping appearance,resembling bristles of a brush.During the healing stage,the provisional zone of calcification reappeared and becamethick,or casted a transverse linear shadow of increased density in the rachitic metaphysiseither close to the epiphysis or on the diaphyseal side,or showed mottled calcificationscattered in the metaphyseal area.The earliest lesion appeared at the distal ends of the ulna involving one or bothcorners.At the same time,we had measured the width of the epiphyseal plate of the tubularbones in 34 normal children below 3.It is emphasized that while measuring theepiphyseal plate,the distal end of the femur at the intercondylar area is most reliable.From the above analysis of the cases,we suggested a roentgen classification ofrickets.更多还原
