Vertebral implant and connector

An implant system comprising:

• an iliac bone screw including a posterior head and an anterior threaded shaft configured to penetrate bone, the posterior head including an inner surface that defines a first cavity that defines a first axis, the inner surface including axial splines oriented along the first axis and circumferentially disposed about the inner surface, the distal portion defining a longitudinal axis disposed transverse to the first axis;
• a connector extending between a first end and a second end, the first end including a first disk having a first face including a threaded shaft extending in a posterior orientation therefrom and defining a first splined surface, the first end of the connector further including a side surface defined between the first face and a second face, the second end including an outer surface comprising axial splines circumferentially disposed thereabout, the axial splines of the posterior head being engageable with the axial splines of the second end in a configuration for selective angular fixation of the iliac bone screw with the connector;
• and
• a receiver including a second disk having a second splined surface that mates with the first splined surface and defining an opening configured for disposal of the shaft, the receiver further including a nut engageable with the threaded shaft to retain the receiver with the connector, the receiver further including a laterally extending arcuate arm, the side surface and the arcuate arm defining an implant cavity defining a second axis such that the implant is captured between an inner surface of the arcuate arm and the side surface,
• wherein the implant cavity is rotatable about a third axis disposed transverse to the second axis such that a vertebral rod disposed in the implant cavity and lateral to the first end of the connector is selectively rotatable in a coronal plane of a body relative to the first end of the connector in a configuration for selective angular fixation with the first end of the connector.

A method for treating a disorder, the method comprising the steps of:

• providing an implant system comprising:
• a fastener including a proximal portion and a distal portion, the proximal portion including an inner surface that defines a first cavity that defines a first axis, the distal portion defining a longitudinal axis disposed transverse to the first axis,
• a connector extending between a first end and a second end configured for disposal in the first cavity, the first end of the connector including a side surface defined between a lower surface and an upper surface of the first end of the connector, and
• a receiver attachable to the first end of the connector and including a laterally extending arcuate arm, the side surface and the arcuate arm defining an implant cavity defining a second axis, the implant cavity being rotatable about a third axis disposed transverse to the second axis such that the implant is captured between an inner surface of the arcuate arm and the side surface;
• attaching the distal portion of the fastener with iliac bone;
• disposing an implant in the implant cavity such that the implant is lateral to the first end of the connector;
• selectively rotating the implant in a first plane relative to the first end of the connector;
• and
• locking the receiver with the connector in a selected angular orientation of the implant relative to the connector.
