  • Publication number: 20040193175
    Abstract: A gauge (10) for measuring bone contour (12) of a bone(4) for use in joint arthroplasty is provided. The gauge (10) includes a body (14) and a probe (16). The body (14) has a body contact portion of the body (14) for contact with the bone (4). The probe (16) is movably positional with respect to the body (14). The probe (16) includes a probe contact portion of the probe (16) for contact with the bone (4). The relative position of the probe (16) with respect to the body (14) is indicative of the bone contour (12) of the bone (4).

  • Publication number: 20040193168
    Abstract: An instrument(10) for use in performing arthroplasty is provided. The instrument(10) includes a first portion(11) adapted to prepare a convex surface(64) on the head(5) of the long bone(4). The instrument (10) also includes a second portion (13) adapted to prepare an elongated cavity (62) or a third portion (14) adapted to prepare a central support surface (56) on the head (5) of the long bone (4), or both second portion (13) and the third portion (14). The third portion (14) and the second portion (13) are operably associated with the first portion(11).

  • Patent number: 6699289
    Abstract: A glenoid component for securement to a glenoid surface of a scapula so as to provide a bearing surface for a head portion of a humerus includes a body having a first surface configured to contact the glenoid surface of the scapula and a second surface configured to receive the head portion of the humerus. The glenoid component also includes an interruption such as a buttress extending from the body. The interruption is configured to be received in a like-configured notch formed in the glenoid surface of the scapula. The interruption helps prevent movement of the glenoid component relative to the glenoid surface of the scapula after implant. The body also may include anchoring extending from the body for penetrating the glenoid surface of the scapula so as to help secure the body to the glenoid surface of the scapula. The glenoid component is used in one application to help correct bone defects and in another application for wear.
