Periprosthetic extension plate
First Claim
1. A fixation system comprising:
- an elongate plate including an inner wall defining a longitudinal axis thereof; and
an extension plate having first and second attachment portions offset from one another, the first attachment portion including a base for receipt in the elongate plate and a projection coupleable to the inner wall of the elongate plate and extending outwardly from the base in a direction transverse to the longitudinal axis of the elongate plate when the projection is coupled to the inner wall of the elongate plate, and the second attachment portion defining a longitudinal axis thereof and including an aperture for receiving a fastener therethrough,wherein the second attachment portion of the extension plate is revolvable about the longitudinal axis of the inner wall when the first attachment portion of the extension plate is coupled to and movable about the inner wall, andwherein the longitudinal axes defined by the inner wall of the elongate plate and the aperture of the second attachment portion of the extension plate are nonparallel when the extension plate is detached from the elongate plate.

Abstract
A fixation system includes an elongate plate and an extension plate. The elongate plate includes an inner wall and has a longitudinal axis. The extension plate has first and second attachment portions offset from one another. An engagement portion extends outwardly from the first attachment portion. The engagement portion is couplable to the inner wall of the elongate plate. The second attachment portion defines an aperture for receiving a fastener. The second attachment portion is revolvable about the longitudinal axis of the inner wall when the engagement portion is coupled to and movable about the inner wall. A fastener is received into the first attachment portion to attach the extension plate to the elongate plate. Another fastener is received into the second attachment portion and into a bone part.

15. An extension plate for at least partial receipt within an elongate plate having at least one inner wall defining an aperture, comprising:
-
a body; a plug segment extending from the body for receipt within the elongate plate, the plug segment having a plug segment surface compressible against and rotatable within the inner wall of the aperture of the elongate plate and having an aperture opposite the plug segment surface defining a longitudinal axis thereof; and a receiving segment having at least one inner surface defining an aperture for receiving a fastener, the inner surface defining a longitudinal axis thereof, wherein the longitudinal axes defined by the aperture of the plug segment and inner surface of the receiving segment are nonparallel, and wherein upon rotation of the plug segment, the longitudinal axis defined by the inner surface of the receiving segment moves along an arc. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of performing osteosynthesis of a bone part or fragment, comprising:
-
receiving a first fastener into a first portion of an extension plate defining a longitudinal axis, wherein the first portion of the extension plate extends into a hole defined by an inner wall of an elongate plate to attach the extension plate to the elongate plate such that the first fastener does not contact the elongate plate and such that the first portion of the extension plate lies between the first fastener and the inner wall; and receiving a second fastener into a second portion of the extension plate and into a bone part or fragment, the second portion of the extension plate defining a longitudinal axis, wherein the longitudinal axes defined by the first and second portions of the extension plate are nonparallel when the extension plate is detached from the elongate plate, and wherein the first portion of the extension plate is rotatable such that the second portion is movable relative to the elongate plate. - View Dependent Claims (26, 27, 28)
