20100004754 | METHOD AND APPARATUS FOR USE OF POROUS IMPLANTS - An orthopedic prosthesis for implantation into a bone of a patient includes a porous metal shell adapted to be affixed within the bone. The porous metal shell includes an outer surface adapted to receive bone ingrowth and an inner surface adapted to engage a liner. The porous metal shell is porous from the outer surface to the inner surface. A non-porous member may be affixed to the porous metal shell. The non-porous member may include a piercing member extending from the outer surface, the piercing member adapted to penetrate the bone in an implanted position. The non-porous member may include spikes or fins. In one example, the piercing member may define a reduced material cross section at an interface with the outer surface of the porous metal shell. The piercing member may be adapted to be broken at the reduced material cross section and removed from the porous metal shell. | 01-07-2010 |
20100131068 | Porous Titanium Modular Revision Patella System - A patellar implant includes a posterior portion and an anterior portion. The posterior portion can have a first radial sidewall that extends between an outboard face and an inboard face. The outboard face can include an articulating surface. The inboard face can include one of a stem and a recess, and one of an annular central hub and an annular radial pocket. The anterior portion can have a second radial sidewall that extends between a tissue engaging surface and a posterior portion engaging surface. | 05-27-2010 |
20100174378 | Knee Joint Prosthesis System and Method for Implantation - A prosthesis system for replacing a knee joint between a femur and a tibia can include a femoral component, a tibial component, a bearing, a first yoke, and a first key. The femoral component can include a first condylar portion, a second condylar portion, a first sidewall extending superiorly from the first condylar portion, a second sidewall extending superiorly from the second condylar portion where the first and second sidewalls collectively comprise a first hinge portion. The tibial component can have a bone engaging inferior surface and a bearing engaging superior surface. The bearing can have an inferior that engages the bearing engaging surface and a superior femoral engaging surface. The bearing can define an opening. The first yoke can have an inferior portion, a superior portion and a yoke keyway extending through the therethrough. | 07-08-2010 |
20110218641 | Modular Lateral Hip Augments - An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complimentary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant. | 09-08-2011 |
20120046755 | Prosthetic Hip Device and Associated Method - A prosthetic device for replacement of a first pelvic portion of a pelvis of a patient opposite to a second pelvic portion relative to a median plane includes an acetabular component a flange component and a pubis component. The acetabular component has a first connecting portion and a second connecting portion at an angle relative to the first connecting portion, the angle selected for a corresponding anatomy of the patient. The flange component is coupled to the first connecting portion and configured to attach to a healthy pelvic portion on a same side of the median plane from the first pelvic portion. The pubis component is connected to the second connecting portion of the acetabular component and having a clamping portion configured to attach to a healthy pubis bone on an opposite side of the median plane from the first pelvic portion. | 02-23-2012 |
20120296438 | KNEE JOINT PROSTHESIS SYSTEM AND METHOD FOR IMPLANTATION - A prosthesis system for replacing a knee joint between a femur and a tibia can include a first femoral component including a first condylar portion, a second condylar portion, a first sidewall extending superiorly from the first condylar portion and a second sidewall offset from the first sidewall a first distance and extending superiorly from the second condylar portion. A tibial component can have a bone engaging inferior surface and a bearing engaging superior surface. A bearing can have an inferior surface that engages the bearing engaging surface and a superior femoral engaging surface. The bearing can define an opening and a bearing keyway. A first yoke and a second yoke can each have an inferior portion, a superior portion, and a yoke keyway extending therethrough. | 11-22-2012 |
20130274889 | Modular Lateral Hip Auguments - An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complementary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant. | 10-17-2013 |
20140277535 | Knee Prosthesis System - A knee prosthesis system constructed in accordance to one example of the present disclosure can include a femoral component, a tibial component, a first femoral component insert, a second femoral component insert, a first tibial bearing, and a second tibial bearing. The knee prosthesis system may be configured in one of a non-hinged configuration and a second hinged configuration. In the first non-hinged configuration, the first femoral component insert is positioned relative to the femoral component and the first tibial bearing is positioned onto the tibial component. In the second hinged configuration, the second femoral component insert is positioned relative to the femoral component and the second tibial bearing is positioned onto the tibial component. | 09-18-2014 |
