Abstract:
1. An orthopedic implant comprising: a first member defining a longitudinal axis, a first wall and a second wall, the first wall defining at least a portion of a chamber and the second wall defining a first axial face comprising an opening defining a first graft containment cavity, the second wall having a tubular configuration and further defining at least one lateral opening, the chamber being separate from the first graft containment cavity, wherein the first member defines a fluid receiving port configured to communicate with the chamber only, the first member includes a transverse wall separating the chamber and the first graft containment cavity, the transverse wall has a reservoir therein in communication with the chamber, and the implant comprises a lumen connecting the reservoir with the fluid receiving port; and a second member defining a first wall having an outer surface configured to engage an inner surface of the first wall of the first member such that the first wall of the second member is disposed for sealed engagement with the first wall of the first member, the first wall of the second member defining at least a portion of the chamber, the second member being configured for movement along the longitudinal axis relative to the first member; and a third member defining a first wall having an outer surface configured to engage an inner surface of the first wall of the second member such that the first wall of the third member is disposed for sealed engagement with the first wall of the second member, the first wall of the third member defining at least a portion of the chamber and a second axial face opposite the first axial face comprising an opening defining a second graft containment cavity, the chamber being separate from the second graft containment cavity, the third member being configured for movement along the longitudinal axis relative to the second member, wherein the members are disposed in a telescopic arrangement such that the sealed engagement of the members facilitates expansion of the members under a fluid pressure in the chamber for movement between a first orientation and a second orientation such that the first member and the third member are disposed to engage adjacent bone surfaces.
