腕高率在RA中的临床应用价值

CIinician practice RA in of Carpal Height Ratio

目的:探讨腕高率对判断RA腕骨塌陷的临床意义。方法:搜集资料完整经临床确诊并摄双手腕正位像的RA40例。按X线分期和有无掌指骨尺偏分6组测量其腕高率。结果:早期CHR(36)=0.512,中期CHR(26)=0.514,晚期CHR(18)=0.455。无尺偏组:CHR(69)=0.502,尺偏小于15°组:CHR(10)=0.484,尺偏大于15°组:CHR(1)=0.450。结论:腕高率对研究RA腕骨塌陷的发展或演变有十分重要的临床价值。

Objective： To evaluate the clinical significance of judgement about rheumatoid arthritis （RA） carpal subsidence by carpal height ratio（CHR）. Methods： The materials which have been maken definite difgno- sis , including pair of carpal films of 40 cases, were derided into 6 groups to measure carpal height ratio by X- ray stage and deviation of metacarpal and phalanx toward ulna sina. Results： Early stage CHR（36） = 0. 512, Middle stage CHR（26） = 0. 514, Later stage CHR（18） = 0. 455, The group without deviation toward ulna side CHR（69） = 0. 502, The group which deviation was smaller than 15 ：CHR（10） = 0. 484, The group which devi- tion was larger than15＊：CHR（1 ） = 0. 450. Conclusion： Carpal height ratio has very importmant chinical signifi- cance to study the development and evolution of rheumatoid arthritis（RA） carpal subsidence.
