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 rod 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, the cap member having an extension portion that is mateable with the housing member,
- wherein the orientations of the rod implant and the anchor member are fixed relative to each other by downwardly inserting the securing member into the housing member.
An orthopedic connection assembly comprising:
- a rod implant;
- an anchor implant;
- a housing member configured and dimensioned to receive the rod implant;
- a securing member receivable in the housing member:
- a plate member receivable within the housing member;
- an interference member in contact with the plate member;
- and
- a receiving member configured and dimensioned to receive the anchor member, wherein the receiving member is capable of operable connection with the housing member and
- wherein the interference member is received at least partially within the receiving member and
- wherein downward insertion of the securing member into contact with the rod implant moves the rod implant into contact with the plate member securing the orientation of the rod implant relative to the anchor member.
The assembly of 19, wherein the inner lumen of the receiving member includes one or more flat surfaces that correspond to the flat surfaces of the interference member.
