Abstract

A spinal bone fastener assembly connects or aligns at least two rods and includes a bone fastener having a bone fastener head and a bone fastener shaft with a shaft axis. The assembly further includes an elongated connector head for receiving the two rods, at least one rod fastener, at least one bone fastener engaging insert and/or at least one rod receiving inlay. The connector head includes one rod receiving passage extending longitudinally or at least two rod receiving passages extending sideways through the elongated connector head. The connector head also includes an elongated bone fastener head receiving recess, which is open to the head bottom side, and at least one locking feature for engaging with the rod fastener. The recess provides at least one translational degree of freedom for the bone fastener, and at least one rotational degree of freedom for the bone fastener around the shaft axis.
