Systems, methods and devices for providing orthopedic implant augments are provided which have fastener locking mechanisms. The augments include a surface for mating with an implant component and a surface for interfacing with a patient's bone. The fastener locking mechanisms are aligned such that the augment may be locked in a variety of orientations while maintaining close contact with both an implant and a patient's bone. The alignment of the locking mechanisms provides variability and adjustability to the augment to address a variety of bone anatomies and requirements.

Orthopedic implant augments

A modular variable 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 linear and angular orientations of the blade component relative to the augment component when the body segment is positioned in the first opening. Additionally, the body segment has a length that is sized to facilitate direct contact of the face segment with the acetabular shell when the modular variable 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.

Modular variable angle blade augment

Piezoelectric osteotomy devices and corresponding systems and methods for removing an acetabular cup or shell from a patient's acetabulum are disclosed. In one embodiment, the piezoelectric osteotomy device includes a piezoelectric element to actuate a cutting tip on an armature. In some such embodiments, the cutting tip may be extended and/or retracted to facilitate cutting of bone around an acetabular cup. The armature may include a fluid output port located proximate the cutting tip to mitigate heat generated by the cutting tip. In one embodiment, the piezoelectric osteotomy device is arranged and configured to provide constant current adjustment.

Devices and techniques for hip revision surgery

Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup and an acetabular cage disposed within an interior of the acetabular cup. The acetabular cage may include a central portion including a first section and a second section rotatably coupled together, and a first flange extending from the first section and a second flange extending from the second section. The acetabular prosthesis may further include a fastener extending through each of the acetabular cup and the central portion of the acetabular cage.

Acetabular apparatuses for hip revision surgery

Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup, a pre-assembled liner and flange construct, and a dual mobility bearing (e.g., a dual articulating femoral head component and insert). In one embodiment, the pre-assembled liner and flange construct may be coupled together by a band coupled to the flanges, the band being arranged and configured to be pressed onto an outer surface of a liner. The pre-assembled liner and flange construct being arranged and configured to accept the dual mobility bearing so that it is freely rotatable relative thereto during use.

Acetabular apparatus with dual mobility for hip revision surgery

An acetabular cage or device () is disclosed. In one embodiment, the acetabular cage includes a cup portion () configured for implantation in an acetabulum and a flange () extending from the cup portion. The flange including a first, bone contacting surface () configured to face bony tissue surrounding the acetabulum when the cup portion is implanted into the acetabulum and a second, top surface () opposite the first surface. The flange includes a flexible portion () and a fixation portion (), the fixation portion including one or more fixation features () configured to facilitate fixation of the flange to the bony tissue surrounding the acetabulum. The flexible portion is arranged and configured to enable the flange, and hence the fixation portion, to move relative to the cup portion to facilitate placement of the flange relative to the bony tissue.

Flexible acetabular implant

A device, for example a medical implant, and a method of making the same, the device having a metal or metal alloy substrate, for example cobalt chrome, and a diffusion hardened metallic surface, for example a plasma carburized surface, contacting a non-diffusion hardened surface or a diffusion hardened surface having a diffusion hardening species different from that of the opposing surface.

Modular variable blade augment

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, an inner surface that interfaces with an implant and having 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 lateral direction from the port.

Orthopedic augments having recessed pockets

A modular acetabular cup assembly for use with multiple bearing liners is disclosed. The acetabular cup assembly includes a shell having a tapered inner wall and two circumferential grooves. The shell may be used with polyethylene, ceramic, metal, and other types of liners.

Acetabular cup assembly for multiple bearing materials

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. Any of the implantable components may be include one or more porous surfaces. The porous surface may be textured by protrusions that connect to and extend from the surface. The sizes and concentration of the protrusions may be varied for specific applications to accommodate different implants and patient anatomies. A porous implant may also include one or more internal or external solid portions that strengthen the implant.
