Abstract

A bone fastener assembly and a method of stabilizing a bone using such an assembly are presented. The bone assembly includes a bone fastener and a connecting member for holding a stabilizing member, such as a rod or plate, wherein the connecting member has a side-opening for accepting the rod therein. Optionally the bone fastener system also permits the bone fastener to pivot relative to a longitudinal axis of the assembly, and is provided with an armature that allows the connecting member to be offset from the longitudinal axis of the bone fastener and for the connecting member to swivel about the longitudinal axis of the assembly. By allowing the rod to be inserted into the connecting member via this side-opening the bone fastener provides a system that is particularly useful for minimally invasive surgeries.

Claims25

Dependent claims

A side-opening bone fastener system for connecting a bone to a stabilizing member comprising:

a bone fastener having an elongated shank including a bone engaging portion at a first end, a head at an opposite, second end, and a longitudinal screw axis extending therebetween;
a connecting member interconnected with said bone fastener, said connecting member having a longitudinal connecting member axis extending in the direction of the longitudinal screw axis, and a rod receiving channel extending at least partially through the connecting member transverse to the longitudinal axis for receiving a spinal rod, the receiving channel having an opening formed in a lateral face of the connection member along the axis of the stabilizing member but laterally offset therefrom such that the stabilizing member may be placed into the receiving channel of the connecting member laterally from the side of said connecting member.

Dependencies are inferred from the claim text.
