Methods of implanting orthopedic devices

摘要

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. An implant may include abuse member that has at least two projections with a gap between the projections. The gap between the projections allows the implant to be implanted around another implanted component, such as around a bone screw of an acetabular shell. The implant may include a fixation element, such as a screw or a cement trough, on one or more projections to couple the implant to an implanted acetabular shell. The implant may also include timing marks to facilitate alignment with corresponding marks on another implanted component.

主权项

1. A method of implanting an orthopedic device in a patient's acetabulum, the method comprising:
preparing the patient's acetabulum to receive an acetabular shell; securing the acetabular shell using at least one bone screw; preparing a space in the patient's acetabulum by use of a broach; inserting an augment into the prepared space, the augment comprising at least two projections defining a gap therebetween, one or more of the at least two projections comprising a cement trough, wherein the augment is inserted into the prepared space by positioning the augment around the at least one bone screw such that the bone screw extends through the gap; and after inserting the augment into the prepared space, securing the augment by pouring cement into the cement trough.
