Abstract
Systems, devices, and methods for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, and an inner surface that interfaces with an implant, the inner surface defining a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a direction laterally from the port.
Claims20
A method of utilizing an orthopedic augment structured for use with an orthopedic implant, wherein the augment is rigid and includes a porous outer surface, an inner surface defining a recessed pocket having a fixed shape, a port extending through the outer surface and the inner surface to the pocket, and a rim structured to flushly engage the implant, the method comprising:
- positioning the augment against the implant with the rim flushly engaged with the implant, thereby partially enclosing the pocket having the fixed shape;
- and
- affixing the augment to the implant with the rim flushly engaged with the implant, wherein the affixing includes inserting a fluid fixation material into the pocket via the port.
A method of utilizing an orthopedic augment structured for use with an orthopedic implant, wherein the augment includes a porous outer surface, an inner surface defining a recessed pocket, a port extending through the outer surface and the inner surface to the pocket, and a rim structured to flushly engage the implant, the method comprising:
- positioning the augment against the implant with the rim flushly engaged with the implant, wherein the positioning of the augment against the implant includes positioning a gasket between the rim and the implant such that the rim flushly engages the implant via the gasket;
- and
- affixing the augment to the implant with the rim flushly engaged with the implant, wherein the affixing includes inserting a fluid fixation material into the pocket via the port.
A method of utilizing an orthopedic augment structured for use with an orthopedic implant having a tissue-facing surface, wherein the augment includes an outer surface, an inner surface defining a recessed pocket, a port extending through the outer surface and the inner surface to the pocket, and a rim structured to flushly engage the tissue-facing surface of the implant, the method comprising:
- inserting the augment into a cavity of a surgical site, wherein the cavity is formed between a first portion of the tissue-facing surface and tissue defining a first surface of the surgical site, wherein a second portion of the tissue-facing surface is in contact with bone tissue defining a second surface of the surgical site, and wherein the inserting includes flushly engaging the rim with the first portion of the tissue-facing surface;
- and
- inserting a fixation material into the pocket of the augment via the port, thereby affixing the augment to the implant.
