20150127113 | Orthopedic Instrument, System and Method for Implanting an Acetabular Cup - An orthopedic instrument for installing a new reverse hip prosthesis, particularly the acetabular cup thereof, wherein the cup can be affixed to the pelvis with or without screws. The acetabular cup is releasably attached to the instrument and the instrument is used to position the cup in the pelvis. Optional screw guides are provided in the instrument in case the surgeon wishes to use screws to affix the cup to the pelvis. | 05-07-2015 |
20140200675 | Lined Femoral Cup - The lined femoral cup of the invention is used in a new reverse hip prosthesis wherein the cup is affixed to the femur and the ball is affixed to the acetabulum. This permits installation of the liner in the factory instead of the operating room. Prior art hip prostheses require installation of the liner in the operating room because the cup must be affixed to the acetabulum, usually by screws, before the liner can be installed. Thus, in a preferred embodiment of the invention the liner is installed under high pressure in the factory. In a second embodiment, a threaded cap is used which permits replacement of the liner without removing the cup from the patient. | 07-17-2014 |
20140128982 | Interlocking Reverse Shoulder Prosthesis and Method - An interlocking reverse shoulder prosthesis including a glenoid cup being implanted in the glenoid fossa having a glenoid ball, firmly attached to the central portion of the cup via Morse taper. The humeral component having a hemispherical cup attached to the neck of the implant via Morse taper in a modular fashion thereby allowing use of several neck lengths. After implantation of the glenoid cup, glenoid hall and the humeral cup, the members are assembled together for relative movement. The glenoid cup is secured by several screws or resorbable fixation studs. During range of motion, the edge of the humeral cup becomes inserted into a gap located between the glenoid cup and the glenoid ball and becomes restrained thus reducing the likelihood of dislocation during extreme range of motion. | 05-08-2014 |
20140025178 | Interlocking Reverese 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. The acetabular cup has a stem extending from the center of a concave portion thereof and an acetabular ball is attached to the stem. A femoral implant has a femoral cup attached to the proximal end thereof. The femoral cup has a stem which can be made with several stem lengths in order to accommodate the various sizing requirements of 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. | 01-23-2014 |
20130345823 | Interlocking Reverse Hip Revision Prosthesis and Method - A reverse hip prosthesis comprising an acetabular cup for implanting in a previously implanted acetabular cup. The acetabular cup is secured to the previously implanted acetabular cup using an o-ring. 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. 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 constrained, thus reducing the likelihood of dislocation during extreme ranges of motion. | 12-26-2013 |
