A fastener assembly for engaging vertebral elements has a connecting body that includes a receptacle extending between a first opening and a second opening and a fastener with a head movably supported in the receptacle. The fastener includes a vertebral engaging portion extending distally through the second opening. The fastener assembly further includes a post that has an elongated body with a proximal portion extending proximally from the first opening of the connecting body, a distal engagement end in the receptacle, and an adjusting portion extending between the proximal portion and the engagement end. The adjusting portion is movably engaged to the connecting body to position the engagement end relative to the head of the fastener to substantially fix the head in the receptacle and resist movement of the fastener with respect to the post and the connecting body.
