    • A fastener assembly (12) for engaging vertebral elements has a connecting body (22) that includes a receptacle (40) extending between a first opening (36) and a second opening (38) and a fastener (20) with a head (26) movably supported in the receptacle (40). The fastener (20) includes a vertebral engaging portion (30) extending distally through the second opening (38). The fastener assembly (12) further includes a post (24) that has an elongated body with a proximal portion (44) extending proximally from the first opening (36) of the connecting body (22), a distal engagement end (56) in the receptacle (40), and an adjusting portion (48) extending between the proximal portion (44) and the engagement end (56). The adjusting portion (48) is movably engaged to the connecting body (22) to position the engagement end (56) relative to the head (26) of the fastener (20) to substantially fix the head (26) in the receptacle (40) and resist movement of the fastener (20) with respect to the post (24) and the connecting body (22).
    • 用于接合椎骨元件的紧固件组件(12)具有连接体(22),该连接体包括在第一开口(36)和第二开口(38)之间延伸的容器(40)和具有头部(26)的紧固件 )可移动地支撑在所述插座(40)中。 紧固件(20)包括沿着第二开口(38)向远侧延伸的椎骨接合部分(30)。 所述紧固件组件(12)还包括柱(24),其具有细长主体,所述主体具有从所述连接体(22)的所述第一开口(36)向近侧延伸的近端部分(44),远端接合端 所述容器(40)以及在近端部分(44)和接合端(56)之间延伸的调节部分(48)。 调节部分(48)可移动地接合到连接体(22)以相对于紧固件(20)的头部(26)定位接合端部(56),以将头部(26)基本上固定在容器(40)中 )并且抵抗紧固件(20)相对于柱(24)和连接体(22)的移动。
