Publication number: 20240138854Abstract: A broach for preparing bone for receiving an anchor for a prosthesis comprises a body comprising a superior surface and a socket extending into the superior surface, and an anchoring component extending from the body comprising a spoke extending laterally from the body and a spoke tip extending proximally from the spoke above the superior surface. A system can comprise a distal broach component comprising a broach body, a socket extending into a superior surface of the broach body, and a plurality of cutting spokes extending radially from the broach body, each of the plurality of cutting spokes separated by an interval pattern, and a proximal broach component comprising a spacer body configured to attach to the superior surface of the broach body, and a plurality of spacer spokes extending radially from the spacer body, each of the plurality of spacer spokes separated by the interval pattern.Type: ApplicationFiled: October 9, 2023Publication date: May 2, 2024Inventors: Cody Johnathon Holmes, Michael Mueller, Steven E.

Patent number: 10188530Abstract: The present disclosure provides a provisional tibial prosthesis system for a set of prosthetic knee joints for implantation in a natural knee, the provisional tibial prosthesis system including a bearing component and a bearing support, the spacing of the bearing component from the bearing support is adjustable to allow for representation of a variety of different sized final tibial prostheses. In this system, only one provisional bearing component corresponding to each level of constraint is needed and shims are used to adjust the spacing of the bearing component from the beating support. The shims are slidably insertable between the bearing component and the bearing support in an anterior/posterior direction to allow for adjustment of the spacing of the bearing component from the bearing support. The number of provisional components needed during knee surgery is reduced and adjustment of the system only requires the knee joint to be distracted by a distance equal to the height of a particular shim.Type: GrantFiled: September 13, 2017Date of Patent: January 29, 2019Assignee: Zimmer, Inc.Inventors: Jody L. Claypool, Steven E. Stump

Patent number: 10010330Abstract: 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.Type: GrantFiled: February 17, 2017Date of Patent: July 3, 2018Assignee: Zimmer, Inc.Inventors: Jody L. Claypool, Steven E. Stump, Wayne Paprosky, David Lewallen, Stephen E. White

Publication number: 20150359642Abstract: 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.Type: ApplicationFiled: August 24, 2015Publication date: December 17, 2015Inventors: Jody L.

Publication number: 20120101505Abstract: A patellar resection instrument has an integral depth adjustment assembly that is easily, intuitively, and intra-operatively adjustable between a plurality of discrete positions. Each position corresponds to a particular, known depth of resection, and this depth may optionally be inscribed on the depth adjustment knob for easy visual selection and/or confirmation of the resection depth. The depth adjustment assembly provides positive tactile feedback as the stylus is moved between positions. The unique configuration of the depth adjustment assembly maintains the resection depth stylus in a chosen position throughout the patellar resection procedure, even if the procedure causes vibration or other forces to be transmitted to the patellar resection instrument.Type: ApplicationFiled: October 26, 2010Publication date: April 26, 2012Applicant: ZIMMER, INC.Inventors: Jody L.
