Disclosed herein are a system and method for attaching an implant, such as an acetabular cup, to an adapter connector without requiring rotation of the connector or the implant, to allow for easy connection, manipulation, and insertion of the implant into a patient. An adapter connector or adapter inserter can include a collet and a collet spreader. The collet can include an exterior surface and an interior surface. The exterior surface can define a protuberance sized to engage an indentation in an adapter. The interior surface can define a collet cavity. The collet spreader can be located at least partially within the collet cavity. The collet spreader can include a flared surface and an engagement surface. The flared surface can be located at a first end of the collet spreader and arranged to engage the interior surface of the collet so as to cause the collet to expand.

An acetabular cup prosthesis comprises an outer cup (1) and a liner (2), in which an inner surface of the outer cup (1) is provided with an abutting face (11) in a circumferential direction thereof; an outer surface of the liner (2) is provided with a protruding snap ring (21) at a bearing part, and is provided with an elastic locking tongue (22) at a non-bearing part; and the protruding snap ring (21) and the elastic locking tongue (22) both abut against the abutting face (11), such that the liner (2) is self-locked in the outer cup (1).

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.

A surgical implant system includes an implant and a fixation member for securing the implant to tissue. The implant and the fixation member together comprise a single monolithic structure. The implant includes an insertion instrument. The implant, the fixation member, and the insertion instrument together comprise a single monolithic structure and are constructed from a single material. The implant is monolithically connected to the fixation member at a first frangible connection and is monolithically connected to the insertion instrument at a second frangible connection. Each of the frangible connections can be broken when force is applied.

An orthopaedic implant includes an acetabular bearing and an acetabular shell component. The bearing includes a convex outer surface having a hemispherical surface, a curved lead-in surface, a flat flange surface, a curved relief surface, and a flat tapered surface. The curved relief surface extends inward relative to the flat tapered surface, and the flat flange surface extends outward relative to the flat tapered surface. The shell component includes a concave inner surface having a tapered surface configured to engage the tapered surface of the bearing. An annular groove is defined in the concave inner wall of the shell component and is configured to receive the flat flange surface. Methods for assembling and using the prosthetic implant are also disclosed.

An acetabular prosthesis assembly includes an acetabular shell component and an acetabular bearing component. The shell component includes a concave inner wall having a tapered surface with multiple anti-rotation slots defined therein. The bearing component includes a convex outer wall as well as an annular flange and multiple anti-rotation keys extending radially outward from the outer wall. When the anti-rotation keys are positioned in rotational alignment with the anti-rotation slots, the flange of the bearing component is positioned in contact with the tapered surface of the shell component. When the anti-rotation keys are positioned out of rotational alignment with the anti-rotation slots, the flange is spaced apart from the tapered surface. Methods for assembling and using the acetabular prosthesis assembly are also disclosed.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

Aspects of the present disclosure include a device for forming a custom cement cast of an acetabular implant for a patient. The device includes an elongated handle, and a head coupled to a proximal end of the elongated handle. The head includes a body, a circumferential lip, and a nipple. The body of the head is shaped as a spherical cap, and includes a circular base and an apex. The circumferential lip extends radially outwardly from the circular base of the body. The nipple extends from the apex of the body in a direction perpendicular to the circular base.

A surgical guide system includes a shell trial having a convex side configured to engage an acetabulum, a concave side forming a cavity therein, and windows extending through the convex and concave sides for viewing bone. The system further includes a liner trial having a convex side configured to be received within the cavity of the concave side of the shell trial, and a concave side with recessed hole guides there, wherein more than one of the hole guides align with the windows of the shell trial when the liner trial is received therein. The system further includes an acetabular cup implant having a convex side configured to engage an acetabulum, a concave side, and a thickness extending between the concave and convex sides, the concave side defining a cavity configured to receive the liner trial.

A cup impactor (1, 1′, 1″) is provided, adapted to assist a surgeon in controlling implantation of a cup prosthesis (9). The impactor has an impactor body (8), a drive train assembly (71), an impactor nose (38), and a clamping handle (5). The impactor body (8) has on its proximal end, an impaction plate (7) connected thereto, and an impactor handle (6) formed thereon for handling by the surgeon and, on the distal end, an impactor cup support portion (8a) having a receiver recess (8b) therein. A drive train assembly (71) has a prosthesis engaging interface (11) at a distal end thereof, and a proximal end on which a positioning knob (2) is formed. The assembly (71) received and rotatably mounted in the receiver recess (8b) of the body (8) so as to expose the prosthesis engaging surface (11). An impactor nose (38) mounts on the distal end of the impactor body (8), through which the prosthesis engaging interface (11) extends. A clamping handle (5) pulls distal portion of the drive train assembly (71) and therefore any cup prosthesis (9) attached to the engaging interface (11) against the impactor nose (38) so as not to strain the proximal end of the drive train assembly (71).
