    • A prosthetic elbow replacement includes a humeral component having a stem dimensioned to fit within a medullary canal of the humerus and having a yoke connected to the stem wherein the yoke terminates in spaced apart arms. A pivot pin is mounted between the arms for rotational movement with respect to the humeral component. The pivot pin has a transverse throughhole. There is an ulnar component having an ulnar stem including a distal end dimensioned to fit within a medullary canal of the ulna and an opposite proximal end dimensioned to fit within a first end opening of the throughhole. The ulnar component has a mounting cap dimensioned to fit within a second end opening of the throughhole. A fastener connects the ulnar stem and the mounting cap such the proximal end of the ulnar stem is positioned within the first end opening of the throughhole and the mounting cap is positioned within the second end opening of the throughhole. The pivot pin rotates to allow for flexion of the prosthetic elbow replacement, and also allows for axial rotation of the ulna component in the humeral component.
    • 人工肘关节置换器包括肱骨部件,该肱骨部件具有尺寸适合安装在肱骨的髓管内并具有连接到该躯干的轭的躯干,其中该轭终止于间隔开的臂中。 枢轴销安装在臂之间用于相对于肱骨部件旋转运动。 枢轴销具有横向通孔。 存在尺骨部件,该尺骨部件具有尺骨杆,该尺骨杆包括尺寸适合配合在尺骨的髓管内的远端和尺寸适合配合在通孔的第一端开口内的相对的近端。 尺骨部件具有尺寸适合安装在通孔的第二端部开口内的安装帽。 紧固件连接尺骨杆和安装帽,使得尺骨杆的近端定位在通孔的第一端开口内,并且安装帽定位在通孔的第二端开口内。 枢轴销旋转以允许人工肘关节置换的弯曲,并且还允许尺骨部件在肱骨部件中轴向旋转。
