| 20110066246 | Articulating Trials for Prosthetic Implants - A trial system for an implantable joint replacement includes an articular insert having an insert body and an insert post captive to the insert body. The insert post is translatable relative to the insert body while remaining captive to the insert body. An aperture on the insert body forms a path, which may be arcuate, along which the insert post can translate. An axis of rotation about which the insert post translates passes through the insert body, and may be medially offset from the center of the body. A flexible element may connect the insert post to the insert body. In one method of use, the trial system is engaged with a femoral component and a tibial component during a prosthetic total knee joint implantation procedure to determine selection of an implantable articular insert which provides knee joint articulation closely matching the articulation of a natural knee. | 03-17-2011 |
| 20110066247 | Position Adjustable Trial Systems for Prosthetic Implants - A trial system for an implantable joint replacement includes a guide assembly having a baseplate and a guide plate, the guide plate translatable relative to the base plate along a straight path while directly connected to the baseplate. A first adjustment mechanism may selectively control the translational juxtaposition of the guide plate relative to the baseplate. The guide plate may further be rotatable relative to the baseplate around a rotation axis. A second adjustment mechanism may selectively control the rotational juxtaposition of the guide plate relative to the baseplate, and can lock the plates together. The rotation axis may be medially offset from the center of the guide assembly. The guide plate provides in situ positionable cutting guidance for implantation of prosthetic joint components. The system may further include an articulating insert trial mounted on the guide assembly to determine preferred joint alignment and/or optimal positioning of the guide plate. | 03-17-2011 |
| 20110066248 | Position Adjustable Trial Systems for Prosthetic Implants - A trial system for an implantable joint replacement includes a guide assembly having a baseplate and a guide plate, the guide plate rotatable relative to the base plate about a rotation axis extending through the guide plate and the baseplate while directly connected to the baseplate. An adjustment mechanism is actuable to selectively control the rotational juxtaposition of the guide plate relative to the baseplate. The rotation axis may be medially offset from the center of the guide assembly. A single instrument may be used to rotate the guide plate relative to the base plate and lock the plates in the selected juxtaposition. The guide plate provides in situ positionable cutting guidance for implantation of prosthetic joint components. The system may further include an articulating insert trial mounted on the guide assembly to determine preferred joint alignment and/or optimal positioning of the guide plate. | 03-17-2011 |
| 20110125202 | INSTRUMENTATION FOR MOBILE BEARING PROSTHETICS - Knee prosthesis instrumentation including an insertion tool and a removal tool. The insertion tool may include an offset to provide clearance from a femoral component of the knee prosthesis. The removal tool may be wedge shaped to at least partially encircle a post of the knee prosthesis for removal. A mallet may be used with the instruments to provide additional force for prosthesis insertion or removal. A slide hammer may be incorporated into the instruments themselves. | 05-26-2011 |
