20130018478 | PROSTHETIC IMPLANT SUPPORT STRUCTURE - A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components. | 01-17-2013 |
20130261504 | TIBIAL PROSTHESIS SYSTEMS, KITS, AND METHODS - Systems for determining force balance on a knee joint during a surgical procedure are disclosed. A system can include a tibial prosthesis. The tibial prosthesis can include a bearing component, a base component, and a shim component. The bearing component can have a superior articulating surface and an inferior surface. The bearing component can include a top portion, a bottom portion, a frame disposed between the top portion and the bottom portion, and a plurality of sensors disposed between the frame and the bottom portion. The frame can have a plurality of apertures corresponding in size or shape to the plurality of sensors. The base component can have a superior surface and an inferior surface. The shim component can be configured to be slidable between the inferior surface of the bearing component and the superior surface of the base component in an anterior to posterior direction. | 10-03-2013 |
20130261757 | TIBIAL PROSTHESIS SYSTEMS, KITS, AND METHODS - Tibial prosthesis systems for implantation or use in a knee joint are disclosed. A tibial prosthesis system can include a bearing component, a base component, a shim component, and optionally a spacer component. The shim or spacer component can be inserted between an inferior surface of the bearing component and a superior surface of the base component. The insertion of the shim or spacer component can provide spacing adjustment between the bearing and base components. The shim component can include one or both of a medial edge having a different height than a lateral edge or an anterior edge having a different height than a posterior edge. The differing edge height of the shim component can provide a surgeon with knee joint kinematic insight regarding an angled bone cut before the cut is made, and can allow for sizing of an appropriately permanent prosthesis system using a reduced number of provisional components. | 10-03-2013 |
20130261758 | TIBIAL PROSTHESIS SYSTEMS, KITS, AND METHODS - Tibial prosthesis methods for balancing a knee joint during a surgical procedure are disclosed. A method can comprise inserting a first tibial shim component between a tibial bearing component and a tibial base or a tibial plate component in an anterior/posterior direction. The first tibial shim component can include one or both of a medial edge having a different height than a lateral edge or an anterior edge having a different height than a posterior edge. The method can further comprise testing one or more of a stability, a force balance, or a range of motion of a knee joint in which the first tibial shim component is inserted. If the testing result is not satisfactory, the method can include removing the first tibial shim component, and inserting a second tibial shim component between the tibial bearing component and the tibial base or tibial plate component in the anterior/posterior direction. | 10-03-2013 |
20130261759 | TIBIAL PROSTHESIS SYSTEMS, KITS, AND METHODS - Tibial prosthesis systems for implantation or use in a knee joint are disclosed. A tibial prosthesis system can include a bearing component, a base component, a shim component, and optionally a spacer component. The shim or spacer component can be inserted between an inferior surface of the bearing component and a superior surface of the base component. The insertion of the shim or spacer component can provide spacing adjustment between the bearing and base components. The shim component can include one or both of a medial edge having a different height than a lateral edge or an anterior edge having a different height than a posterior edge. The differing edge height of the shim component can provide a surgeon with knee joint kinematic insight regarding an angled bone cut before the cut is made, and can allow for sizing of an appropriately permanent prosthesis system using a reduced number of provisional components. | 10-03-2013 |
20130304221 | TIBIAL AUGMENTS FOR USE WITH KNEE JOINT PROSTHESES, METHOD OF IMPLANTING THE TIBIAL AUGMENT, AND ASSOCIATED TOOLS - A tibial augment for use with a knee joint prosthesis, composed of annular members of different stock sizes, each size being configured to fit within a cavity formed in a human tibia. The augment may include a stepped distal surface. A provisional (temporary) tibial augment used to ensure a proper fit for the permanent augment is also provided. The provisional may include grooves configured to cooperate with a set of ribs on a tong-like holder used for removing the provisional from the cavity. A pusher for use implanting the tibial augment is also provided. In addition, a system for creating a cavity in a human tibia is also described. The system preferably includes a guide with a slot therein and a set of osteotomes that are inserted within different portions of the slot. Methods for using the tools and/or implanting the prosthetic devices discussed above are also described. | 11-14-2013 |

20140296859 | CUT GUIDE ATTACHMENT FOR USE IN TIBIAL PROSTHESIS SYSTEMS - Tibial prosthesis systems for implantation or use in a knee joint are disclosed. A tibial prosthesis system for implantation on a resected tibia can include a bearing component, a base component, and a shim component. The insertion of the shim component can provide spacing adjustment between the bearing and base components. The shim component can have a generally uniform height or thickness, or a variable height. A cut guide attachment, removably attachable to the prosthesis system, can be used to facilitate further resection of the tibia and create one or more additional resection surfaces on the tibia at an angle relative to the first resection surface. Multiple cut guide attachments can be available to the user to provide various resection angles. The cut guide attachment can include a modular design. The cut guide attachment can be configured to adjust the angle of the subsequent resection in at least one direction. | 10-02-2014 |
