桡骨下端的下面为腕骨关节面,与腕骨相关节,关节面分别向掌侧和尺侧倾斜。桡骨下端骨折时,关节面的角度也发生改变,所以,桡骨前倾角和内倾角的大小,直接影响腕关节的功能。国内资料多采用 X 线测量方法统计而得,但由于后前位与前后位投照方式的不同,正常数值存在有3°～4°的差异。迄今尚未见有直接进行测量的报告。本文对太原地区出土的成年干燥完整的桡骨标本进行了直接测量,以兹为临床工 Below the lower end of the radius of the carpal articular surface, and carpal joints, articular surface were respectively inclined to the palm side and ulnar. Radial fracture, the articular surface angle also changed, so the radial anteversion and camber angle, the size of a direct impact on the function of the wrist. Most of the domestic data are obtained by using the X-ray measurement method. However, due to the differences between the former and the latter modes of projection, the normal values ​​have a difference of 3 ° ~ 4 °. So far no direct measurement report has been found. In this paper, Taiyuan area unearthed adult dry intact radial specimens were measured directly to the clinical
