The condylar portions and anterior flange portion together define an outer side of the femoral component for articulating with a tibial prosthesis and an inner bone facing side opposite the outer side. The inner bone facing side defines five intersecting component inner surfaces that each extend from a lateral side of the femoral component to a medial side thereof. A femoral augment includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral augment comprised of five intersecting augment outer surfaces and an inner side comprising no more than three intersecting augment inner surfaces. The augment outer surfaces correspond to the component inner surfaces of the femoral component. The augment inner surfaces correspond to resected surfaces of a distal femur.Type: ApplicationFiled: June 21, 2021Publication date: October 7, 2021Inventors: Damon J. Servidio, Anthony K. Hedley

Publication number: 20210307920Abstract: An expandable intervertebral implant having an upper body portion, a lower body portion opposite the upper body portion, a wedge member connecting the upper body portion to the lower body portion, a nose member having a tapered distal end and a proximal end opposite the distal end, and an actuator disposed between the nose member and the wedge member, for translation of the wedge member along a longitudinal axis of the implant. A pin disposed in a center of the nose member connects to the actuator for centering the nose member with the actuator. Translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.Type: ApplicationFiled: June 18, 2021Publication date: October 7, 2021Inventors: John Lawrence Walker, Joseph Matthew Jones

Publication number: 20210307921Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.Type: ApplicationFiled: June 22, 2021Publication date: October 7, 2021Inventors: Collin Newman, Christian Karl Schultz, Steven Willis, Amir Ali Sharifi-Mehr, Oliver Buchert, Christopher P.
