An intervertebral implant includes opposing upper and lower endplates that are configured to engage respective vertebral surfaces in an intervertebral space. The implant carries a plurality of bone fixation spikes that extend out from each endplate. The spikes define a plurality of outer surfaces that extend from a base to a tip. The spikes are laterally staggered, and have a height that increases along a longitudinal direction from the front toward the rear of the implant, and a define recess formed in at least one outer surfaces.

The three-dimensional lattice structures disclosed herein have applications including use in medical implants. Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing. In some examples, the lattice can be configured as a scaffold to support bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

Provided is an implant configured for implantation in a bone segment, the implant including a first part that includes a hydrogel portion and a porous material portion, and a second part that includes an annular rim and a bottom that at least partially define a cavity configured to receive the porous material portion of the first part, and a barb extending from the bottom of the second part in a direction away from the cavity.

Systems and methods are provided for robotically assisted disc prosthesis selection and implantation. The system includes a 3D modeling system for creating a 3D model of first and second vertebra adjacent the intended surgical site and identifying and storing data for the positions of the first and second vertebrae. A computing system for stores and processes the 3D model and the position data. A robot connected to the computing system attaches to a plurality of instruments including sizing templates, trials, cutters or placement instruments for intervertebral disc prostheses. An interface on the computing system allows the surgeon to sequentially deliver the plurality of instruments with the robot to a registration position to improve the speed and accuracy of the surgical procedure.
