作者对本国200侧成人正常腕部正位X线片之月骨暴露长度、暴露率进行测量,以提供其正常参数值,同时阐明月骨暴露率为分析腕部月骨形态学改变及腕关节不稳提供了客观依据,并可作为腕骨不稳向尺侧移位的定量指标。
The authors measured the length of the lunate and the exposure rate of the orthopedic radiographs of 200 normal adults in the country to provide normal values of the parameters and to clarify the rate of lunate exposure in order to analyze the morphological changes of the lunate bone and the wrist Instability provides an objective basis and can be used as a quantitative indicator of ulnar shift of the carpal bones.
