Abstract
An orthopedic connection assembly is described that comprises a housing member for receiving an implant that is operably connected to a receiving member for receiving an anchor member. The connection assembly is configured to have a locking mechanism that secures and fixes the relative orientation between the implant and the anchor member. The connection assembly can comprise a plate member receivable within the housing member. When a securing member such as a set screw is introduced downwardly into the housing member to secure the implant, the securing member applies a lateral force to the plate member, which presses against an interference member within the receiving member. The interference member presses against the anchor member, such that the anchor member is fixed in a position relative to the implant.
Claims20
An orthopedic connection assembly comprising:
- a housing member including a first aperture for receiving a securing member and a second aperture for receiving a spinal implant;
- a plate member insertable into the housing member through a third aperture;
- an interference member capable of engagement by the plate member;
- a receiving member for receiving the interference member therein, the receiving member including a receiving aperture for receiving an anchor member therethrough;
- and
- a cap member receivable over the receiving member and mateable with the housing member,
- wherein the assembly is configured to allow for a number of variable angles between the spinal implant and the anchor member.
