A variable angle blade augment including an augment component and a blade component. The blade component includes a buttress portion and a neck portion, with the neck portion having a body segment and a face segment that is contoured for mating engagement with an outer surface of the acetabular shell. The augment component has a first opening sized and shaped to receive insertion of the body segment, and which is also sized to accommodate selective adjustment of, when the body segment is positioned in the first opening, linear and angular orientations of the blade component relative to the augment component. Additionally, the body segment has a length that is sized to facilitate direct contact of the face segment with the acetabular shell when the variable angle blade augment is in an assembled configuration. Further, cement can be injected into the internal cavity to unitize the connection between the acetabular shell and the blade component.

Variable angle blade augment

A variable angle blade augment including an augment section and a separate plate or blade segment. According to some embodiments, a first connector of the blade segment and a socket capture mechanism of the augment section provide a ball and socket type joint. Additionally, the socket capture mechanism may be structured to allow for linear displacement of the first connector relative to at least one axis of the socket capture mechanism. By allowing for at least pivotal and linear relative displacement of the augment section and the blade segment, the variable angle blade augment may improve the ability to optimally position a buttress augment against a prosthetic acetabular shell. Moreover, the variable angle blade augment may provide the ability to utilize components of an implantable medical device after stabilizing the components to a bone structure of a patient.
