| 摘要 |
An implant includes a first component including a wall that defines a first surface and a second surface. The first surface defines a first opening and the second surface defines a second opening. The second opening is spaced apart from the first opening to define a cavity therebetween. A second component is supported by the first component and configured for movement relative thereto. The second component is movable between a first configuration such that the second component is disposed between the first opening and the second opening within the cavity and a second, expanded configuration such that the second component simultaneously passes through the first and second openings to extend from the cavity. Methods of use are also disclosed.
