Abstract
A cover for use in protecting a resected surface of a long bone for use in joint arthroplasty is provided. The cover includes a generally planar portion having opposed generally parallel first and second surfaces defining a periphery extending from the first surface and the second surface. The cover also includes a lip extending from the first surface at the periphery of the planar portion in a direction not planar with the generally planar portion.
Claims20
A method for protecting a resected surface of a long bone, comprising:
- resecting an end of the long bone to expose the resected surface;
- placing a cover over the resected end of the long bone, the cover including:
- a body extending along a first plane,
- a first member attached to the body and movable with respect to the body generally along a second plane parallel to the first plane,
- a second member attached to the body and movable with respect to the body generally along the second plane, and
- a third member attached to the body and movable with respect to the body generally along a third plane parallel to the first plane and the second plane;
- adjusting the cover to fit the resected end of the long bone;
- and
- securing the cover to the resected end of the long bone.
A method of protecting a resected surface of a long bone, comprising:
- resecting an end of the long bone to expose the resected surface;
- placing a cover over the resected end of the long bone;
- moving two of a plurality of independently movable members of the cover linearly with respect to a body of the cover along a first plane and along a first axis, from a first position whereat the body and the plurality of independently moveable members define a first periphery of the cover along the first plane, to a second position whereat the body and the plurality of independently moveable members are in a second position with respect to each other, wherein the first periphery encompasses a first area when projected onto the first plane and the second periphery encompasses a second area when projected onto the first plane, the second area larger than the first area and including all of the first area;
- and
- positioning a downwardly extending lip, the lip fixedly positioned along an outer radial periphery of one of the body and the plurality of independently movable members, against an outer surface of the long bone, the outer surface extending downwardly from the resected surface.
A method of protecting a resected surface of a long bone, comprising:
- resecting an end of the long bone to expose the resected surface;
- placing a cover over the resected end of the long bone;
- moving a first member supported by a body of the cover and movable with respect to the body generally along a second plane parallel to a first plane defined by the body between a first position and a second position, the first member including (i) a second surface in opposition to a first surface of the body and (ii) a third surface;
- moving a second member supported by the body and movable with respect to the body generally along the second plane between a first position and a second position, the second member including (i) a fourth surface in opposition to the first surface and (ii) a fifth surface;
- and
- moving a third member supported by the body and movable with respect to the body generally along a third plane parallel to the first plane between a first position and a second position, the third member including a sixth surface in opposition to the third surface and the fifth surface, such that
- when each of the first member, the second member, and the third member is in its respective first position, the body and each of the first member, the second member, and the third member define a first periphery which, when projected onto the first plane, encompasses a first area,
- when each of the first member, the second member, and the third member is in its respective second position, the body and each of the first member, the second member, and the third member define a second periphery which, when projected onto the first plane, encompasses a second area, and
- the second area encompasses the first area and is larger than the area of the resected end of the long bone.
