Abstract: There is proposed a bone fastener assembly comprising a bone fastener comprising a bone fastener head and a bone fastener shaft, a correction instrument and/or a locking insert, and a rod receiving head. The rod receiving head includes at least two rod receiving passages, and which can thus be connected to two rods. Moreover, the movement of the rod receiving head in relation to the bone fastener can be blocked prior to placing a rod into the rod receiving head. The proposed bone fastener assembly may be used for example for correcting larger spinal deformities.

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.

Abstract: A spinal rod connector assembly is provided for connecting and axially aligning two in situ spinal posterior rod portions. The spinal rod connector assembly comprises a rod connector and one or more rod fasteners. The rod connector comprises a rod receiving passage extending between two opposite ends of the rod connector. Seats are provided along the passage to engage with the rod portions when the spinal rod assembly has been implanted. The rod connector comprises one or more locking holes extending from the connector top side into or towards the rod receiving passage. The one or more locking holes being sized and shaped for engaging with the one or more rod fasteners.
