Abstract:
1. A kit for use in performing revision surgery on a cavity in a canal of a long bone, the cavity extending from a resected plane of the long bone, said kit comprising: a canal component defining an external periphery thereof, at least a portion of said canal component to be fitted to the cavity in the canal of the long bone, said canal component including a canal portion, said canal portion defining a first end thereof for insertion into the cavity and an opposed second end, said canal component further including a sleeve portion extending from the second end of the canal portion, the sleeve portion having an internal periphery thereof defining an internal cavity thereof in which a portion of the internal periphery of the sleeve portion is planar and is arranged approximately perpendicular to the longitudinal axis of the canal component the sleeve portion also defining an external periphery thereof, wherein a portion of the external periphery of said canal component is generally planar; a first joint component removably connectable to the canal component, said first joint component having a neck portion and a connection portion, the neck portion extending from the connection portion at an acute angle and the connection portion of said first joint component defining an external periphery thereof, at least a portion of the external periphery of the connection portion of said first joint component being generally rectangular in shape and being sized and shaped to be fitted into the internal cavity of the sleeve portion of said canal component by virtue of a portion of the external periphery of the connection portion being approximately perpendicular to the longitudinal axis of the canal component; a second joint component removably connectable to the canal component, said second joint component having a neck portion and a connection portion, the neck portion extending from the connection portion at an acute angle and the connection portion of said second joint component defining an external periphery thereof, at least a portion of the external periphery of the connection portion of said second joint component being generally rectangular in shape and being sized and shaped to be fitted into the internal cavity of the sleeve portion of said canal component by virtue of a portion of the external periphery of the connection portion being approximately perpendicular to the longitudinal axis of the canal component; and a connector to connect the connection portion of one of said first joint component or said second joint component to said canal component, wherein the connector is in contact to both the connection portion of one of said first joint component and said second joint component and said canal component; wherein the external periphery of the connection portion of said first joint component is spaced inwardly from the external periphery of the sleeve portion of said canal component when said first joint component is fixedly connected to said canal component so that said first joint component may be removed from the long bone and replaced with said second joint component without disturbing the fixation of said canal component to the long bone; wherein the internal cavity of the canal component is sized and shaped to receive the connection portion of the first or second components along the longitudinal axis of the canal component; wherein the internal cavity only includes one opening and a portion of the opening is coaxial with the longitudinal axis of the canal component.
