Abstract: Extraction instruments and systems for use in revision arthroplasty are provided. The extraction instruments are shaped and configured to fit within the typically tight confines in which revision arthroplasty is performed, and to enhance the surgeon's control over the axis, quantum and speed of the force that is required be applied to disrupt a bone-to-prosthesis bond. This enables completion of a revision arthroplasty to proceed more quickly, and with reduced risk that unwanted movements might cause accidental injury to nearby vital structures.

Abstract: Disclosed is a device for hanging boots comprising a mounting bar and a plurality of clips, one for each boot. The mounting bar can be secured to a vertical or horizontal surface and includes a metallic contact surface and an upwardly directed supporting surface. Each clip includes two spring-biased leg members for grasping an article and a magnet for securing the clip to the metallic contact surface of the mount. The upwardly directed supporting surface prevents the clips from sliding off the contact surface because of the weight of the supported boot.
