Research on Coordinated Motion Control Mode for Six-Wheeled Rocker Lunare Rover 六轮摇臂式月球车运动协调控制模式研究
Systemic scleroderma combined with left navicular and lunare necrosis: case report 系统性硬皮病合并左舟、月骨坏死1例
Objective: to discuss the X-ray diagnostic criteria of Colles fracture combined with lunare bone dislocation. 目的:探讨colles骨折合并月骨脱位的x线诊断标准。
The internal fixation instruments for four-corner arthrodesis can be designed according to the data of measurement and the anatomical characteristics of capitatum, lunare, triquetrum and hamate. 依据测量数据及头状骨、月骨、三角骨和钩骨的解剖特点进行设计,可设计适于腕骨四角融合术的内固定器械;
Methods: Lateral view radiographs of 100 cases of Colles fracture combined with lunare bone dislocation and 100 cases of volunteers with normal wrist joint were included and analyzed. 方法:对100例Colles骨折合并月骨脱位及100例正常腕关节的X线正侧位平片进行对比分析,测量月骨中轴线与桡骨中轴线的夹角。
Conclusion: Contacting area and pressure to the navicular and lunare show significant changes when the radiocarpal joint angular reached more than 10 degrees and it leads to significant influence on the wrist joint. 结论:桡腕关节面背倾10°以上时,桡偏10°以上时,舟骨和月骨的接触面积及接触应力有显著变化,影响腕关节功能。
