20100125340 | Acetabular cup with supplemental screw fixation using conical interference fit between screw and cup - A fixation technique is provided whereby a solid metal acetabular cup, such as is used with hip resurfacing implants, or so called “metal on metal” bearings used with traditional total hip replacement, which do use supplemental screw fixation, can achieve immediate fixation to the acetabulum using a acetabular fixation screw, which couples to an acetabular metal cup by way of a precision taper coupling (tapered interference fit) between the fixation screw and the acetabular cup. Under normal loading, the cold weld achieved between the two surfaces is stable, and disassociation between the two metal surfaces can be achieved only with significant force. | 05-20-2010 |
20120022663 | IMPLANT COMPONENTS AND METHODS - 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 a base 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. | 01-26-2012 |
20120065736 | ACETABULAR CUP FIXATION - An acetabular cup system includes an acetabular cup having a wall with an inner surface and an outer surface. The acetabular cup includes a fixation opening through the wall, the fixation opening including a first wall portion adjacent to the inner surface and a second wall portion adjacent to the outer surface. The acetabular cup system also includes a fixation fastener including a head and a shaft with a bone-anchoring portion. The fastener can be inserted though the fixation opening. The head includes a first head portion engageable with the first wall portion and a second head portion engageable with the second wall portion. | 03-15-2012 |
20120265319 | TOTAL HIP ARTHROPLASTY - A total hip arthroplasty includes a femoral prosthesis and an acetabular prosthesis. The femoral prosthesis has a ball on a neck portion of a femoral component including a noncircular femoral body a portion coated with a porous bone ingrowth coating for noncemented fixation within a resected patient femur. The femoral body is tapered, to include a combination of a medial-lateral taper, an anterior-posterior taper, and a lateral-to-medial taper for secure seated fixation into the medullary canal of a resected femur. The acetabular prosthesis includes a hemispherical metal cup having a porous bone ingrowth surface for secure fixation within a prepared patient acetabular socket. A bearing insert is initially seated within the acetabular cup in a “trial” position without locking to determine cup placement and freedom of leg movement, and thereafter reseated in a “lock” position. A femoral broach and a bone punch tool are also provided. | 10-18-2012 |
20130046389 | Acetabular Roof Reinforcement Plate - An acetabular implant has (a) a body including a substantially convex exterior surface configured to be received within and engage an acetabulum and a substantially concave interior surface sized and shaped to receive a head portion of a femur; (b) a rim extending about a periphery of the body and including a plurality of first holes, each of the first holes being configured to lockingly receive a bone fixation element therethrough in an angularly stable configuration; and (c) a flange extending radially from the rim and including a plurality of second holes. Each of the second holes is configured to receive a bone fixation element therethrough in an angularly stable configuration. | 02-21-2013 |
