CUT GUIDE ATTACHMENT FOR USE IN TIBIAL PROSTHESIS SYSTEMS

摘要

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.

主权项

1. A system for performing a surgical procedure on a portion of a knee joint, the system comprising:
a provisional tibial prosthesis system implantable on a first resected surface of a proximal tibia and comprising a tibial base plate, a tibial bearing component attachable to the tibial base plate, and at least one shim slidably receivable between the tibial base plate and the tibial bearing component; and a cut guide removably attachable to the tibial prosthesis system and configured to facilitate further resection of the proximal tibia.
