Offset variable angle connection assembly

摘要

A method of securely connecting a spinal implant to a bone anchor by using an offset connection assembly. The variable angle connection assembly is able to securely connect the spinal implant to the anchors even when there is a variance in the angle and position of the anchors with respect to the spinal implant. The connection assembly will not inadvertently lock the components of the connection assembly preventing the relative movement of the components.

1. A method of securely connecting a spinal implant comprising:
implanting an anchor into a vertebral body; positioning a spinal implant in a housing member of a connection assembly, the connection assembly comprising:
the housing member having a first end and a second end, the housing member having an aperture proximate the first end for receiving a portion of the spinal implant and a channel extending from the second end towards the first end, the channel is in fluid connection with the aperture and oriented generally transversely to the aperture;a connection member having a first end and a second end, the connection member having a lumen, the lumen is in fluid communication with the aperture of the housing member and oriented generally transversely to the aperture of the housing member, the second end of the connection member is received in the channel of the housing member so that the connection member is rotatably and translatably connected to the housing member; anda receiving member having a first end and a second end, the receiving member having an aperture for receiving a portion of the anchor, a resilient leg for contacting the anchor, and a channel extending from the second end to the first end, the channel receives a first end of the connection member; and connecting the receiving member of the connection assembly to the anchor.
