20130289734Interlocking Reverse Hip and Revision Prosthesis - A reverse hip prosthesis comprising an acetabular cup for implanting in an acetabular socket. The acetabular cup is secured to the acetabular socket of the pelvis using fasteners. The acetabular cup has a stem extending from the center of a concave portion thereof and an acetabular ball is attached to the stem, preferably by means of a Morse taper. A femoral implant is provided with a femoral cup attached to the proximal end thereof. The femoral cup has a stem which can be constructed in a modular fashion with several stem lengths in order to accommodate the various sizing requirements of different patients. After implantation of the acetabular cup and ball and the femoral cup, the members are assembled together so that the femoral cup can articulate on the acetabular ball. The prosthesis of the invention has a wide range of motion and substantially improved tribology. As the femoral cup is articulated, the edge of the femoral cup moves into a space located between the acetabular cup and the acetabular ball and thereby becomes restrained, thus reducing the likelihood of dislocation during extreme ranges of motion.10-31-2013
20140309748METHOD FOR PERFORMING AN ORTHOPAEDIC PROCEDURE - A method for performing an orthopaedic surgical procedure on an acetabulum of a patient includes the steps of securing an acetabular shell component to an acetabulum of a patient and securing a first insert to an acetabular shell component configured to be implanted within an acetabulum of a patient. The method further includes the steps of securing a second insert to the first insert such that the outer surface of the second insert contacts the inner surface of the first insert and securing a femoral head configured to be secured to a femoral stem to the second insert such that the outer surface of the femoral head contacts the inner surface of the second insert.10-16-2014
20150025647DUAL MOBILITY HIP REPLACEMENT SYSTEM - A total hip implant system comprising: a prosthetic femoral component having a head with a part-spherical bearing surface; and a dual mobility acetabular cup system comprising a first bearing component made of ultra high molecular weight polyethylene mounted on the head, the first bearing component having a part-spherical inner bearing surface rotatably engaging the part-spherical bearing surface of the head, and having a part-spherical outer bearing surface, a second bearing component made of polyetheretherketone (PEEK) having an inner part-spherical bearing surface rotatably engaging the part-spherical outer bearing surface of the first bearing surface.01-22-2015
20150039091CONSTRAINED MOBILE BEARING HIP ASSEMBLY - An acetabular hip implant includes an acetabular shell component having a first feature and a first insert having a second feature that cooperates with the first feature of the acetabular shell component and further includes a third feature. The implant further includes a second insert having a fourth feature that cooperates with the third feature of the first insert and further includes a fifth feature. A femoral head component includes a sixth feature that cooperates with the fifth feature. Interaction between the first and second features, between the third and fourth features, and between the fifth and sixth features mechanically constrains the acetabular hip implant to prevent dislocation of the femoral head during rotation.02-05-2015

20110054628REFLEX FIXATION GEOMETRY REVISION AND RECONSTRUCTION SYSTEM REVERSE ARTICULATION - An orthopedic device is disclosed for restoring the normal or natural joint mechanics in, for example, a hip joint. The device includes a first component, such as an acetabular component in a hip implant, that includes a convex articulation surface and a second component, such as a femoral component in a hip implant, that includes a concave articulation surface. It will be appreciated that the convex articulation surface of the device disclosed herein articulates with the concave articulation surface in a mating engagement that may be reversed with respect to the traditional hip implant, in which the concave articulation surface is part of the acetabular component and the convex articulation surface is part of the femoral component.03-03-2011
20140303742TOTAL 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.10-09-2014
