Publication number: 20220249251Abstract: An impaction cradle (50) for supporting a femoral (10) or tibial (70) implant on a planar support surface such as a tabletop. The impaction cradle can orient the femoral or tibial implant on the impaction cradle such that an attachment feature of the implant for an intramedullary stem or metaphyseal sleeve is aligned with a vertical plane or parallel to the true vertical axis. In this position, the intramedullary stem or metaphyseal sleeve can be impacted along a generally vertical axis to drive the intramedullary stem or metaphyseal sleeve along an impaction axis parallel to a true vertical axis or positioned within a vertical plane. The generally vertical impaction angle can be easier for medical practitioners to accurately impact the intramedullary stem or metaphyseal sleeve, which lowers the risk of damage to the intramedullary stem, metaphyseal sleeve, or the femoral or tibial implant.Type: ApplicationFiled: April 29, 2022Publication date: August 11, 2022Inventors: Tim Yoko, Amanda Szalkowski, Jeffery A.

Patent number: 10034672Abstract: Tools or other instruments can be used by a surgeon to complete an orthopedic procedure. One tool can include a resection tower and a valgus guide. The resection tower can include a cutting block and a dial coupled with the cutting block. The resection tower can be configured such that rotational movement of the dial, about an axis, effectuates movement of the cutting block along a plane substantially parallel with the axis. The dial, when rotated in a first direction, can move between a first position, which corresponds to a minimum cutting depth of the cutting block, and a second position, which corresponds to a maximum cutting depth of the cutting block. The valgus guide can be coupled with the resection tower and includes a rotatable member. The rotatable member can include an angular surface with one or more variable depth splines providing varus/valgus angle adjustment of the cutting block.Type: GrantFiled: November 5, 2015Date of Patent: July 31, 2018Assignee: Zimmer, Inc.Inventors: Nolan C.
