Abstract: In general, orthopedic instrument adapters and methods of using orthopedic instrument adapters are provided. In an exemplary embodiment, an adapter is configured to releasably attach to an end effector configured to impact bone. The end effector can be a broach, chisel, or other surgical implement. The adapter includes a spring-loaded hook that is configured to releasably seat in a cut-out formed in the end effector. The adapter is also configured to releasably attach to a surgical impacting tool, such as an orthopedic impactor, configured to drive impacting of the end effector relative to bone.

Abstract: An orthopedic prosthesis assembly includes a first prosthetic component, a second prosthetic component, a retainer, and a fastener and allows the removal of the first prosthetic component without having to remove the second prosthetic component from an intramedullary canal of a patient's bone. The fastener is received in an aperture of the first prosthetic component and the retainer is configured to engage the aperture of the first prosthetic component such that a part of the fastener is secured within the aperture. A rod of the fastener is configured to advance along the longitudinal axis through the first prosthetic component into the second prosthetic component. The end of the rod of the fastener is threaded into a threaded bore defined in the second prosthetic component.

Abstract: An articulating fusible support cage comprises a first support member having a first and second end and a second support member having a first and second end. A first end cap is pivotally connected to the first and second support members at the first ends. The first end cap supports a jackscrew for rotation. A second end cap is pivotally connected to the first and second support members at the second ends opposite the first ends. The second end cap has a threaded sleeve configured to engage a portion of the jackscrew. Rotation of the jackscrew into the threaded sleeve causes the first and second support members to extend outwardly from a collapsed condition to a deployed condition.

A first end cap is pivotally connected to the first and second support members at the first ends. The first end cap supports a jackscrew for rotation. A second end cap is pivotally connected to the first and second support members at the second ends opposite the first ends. The second end cap has a threaded sleeve configured to engage a portion of the jackscrew. Rotation of the jackscrew into the threaded sleeve causes the first and second support members to extend outwardly from a collapsed condition to a deployed condition.

Abstract: A removable anchoring pedicle screw includes an implant mounting screw, an anchor screw, and a nose piece. The anchor screw is configured to be rotated relative to the implant mounting screw such that the nose piece engages an expandable anchor. The expandable anchor is disposed between the implant mounting screw and the nose piece such that rotation of the anchor screw relative to the implant mounting screw causes expansion of the expandable anchor.
