The present invention includes a method for generating a three-dimensional model of a bone. The method may further include generating a cut plan for excavating a portion of the bone according to the cut plan to allow the insertion of a custom implant. In a particular arrangement, the method may includes excavating the bone with an autonomous extremity excavator utilizing the cut plan generated by a processor. In a further arrangement, the method may include generating a digital model of a custom implant and generating, using the digital model, a physical model sharing the same dimensions as the digital module using manufacturing device.

Methods, apparatuses, and systems for customized kit assembly for surgical implants are disclosed. A robotic surgical system designs and customizes a surgical implant and its surgical implant components. The surgical implant and its surgical implant components are assembled into a kit that is customized for a specific patient. The robotic surgical procedure using the kit can additionally select from available generic, off-the-shelf surgical implant components or customized surgical implant components.

An interbody spacer for spinal fusion surgery includes first and second opposite side walls that have open-cell metal foam at upper and lower faces, and a three-dimensional lattice disposed between open-cell metal foam at the upper and lower faces. The open-cell metal foam is in communication with the three-dimensional lattice so that bone growth can enter the three-dimensional lattice from the open-cell metal foam. The interbody spacer may be formed by additive manufacturing.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

A method of manufacturing a resorbable, macroporous bioactive glass scaffold comprising approximately 15-45% CaO, 30-70% SiO.sub.2, 0-25% Na.sub.2O, 0-17% P.sub.2O.sub.5, 0-10% MgO and 0-5% CaF.sub.2 by mass percent, produced by mixing with pore forming agents and specified heat treatments.

An intervertebral implant with two opposite contact surfaces configured to bear regionally on vertebral bodies and are spaced apart from each other along a vertical axis and are each arranged on support elements which are adjustable relative to each other. The support elements are guided adjustably relative to each other along a circular arc contour oriented on a longitudinal axis extending perpendicular to the vertical axis in such a way that, by adjustment of the two support elements relative to each other along the circular arc contour, a spacing of the two contact surfaces with respect to the vertical axis and/or an angle setting of the two contact surfaces relative to each other can be predefined and/or modified.

The variable or adjustable depth medical implants in this application are capable of depth adjustment prior to implantation. The variable depth implants permit a single implant to provide multiple footprint configurations, allowing a surgeon footprint adjustability in the operating room. The implants can comprise a metallic lattice designed for specific physical properties, such as an elastic modulus. In some examples, the main body of the implant is taller than the adjustable portion of the implant (also referred to as the second implant body) so that the physical properties of the main body of the implant are controlling at the implant site. In some embodiments, the variable implant is constructed in an additive process as a single unit.

Porous regions are formed using selected additive manufacturing techniques. The porous regions can assist in fibro-inductive regions and/or osteo-inductive regions. A prosthetic member can be formed completely with the additive manufacturing technique and/or the additive manufacturing techniques can be used to form an augment portion that is added to the prosthetic member formed separately.

A prosthesis for replacing a natural articular surface on a bone may have a joint facing side with an articular surface, a bone anchoring side with a bone engagement surface, and a bone engagement pad secured to at least part of the bone engagement surface. The bone engagement pad may have a transverse portion extending transverse to a length of the bone, and one or more protruding portions extending generally perpendicular to the transverse portion. The transverse portion may have a pad bone-facing surface with a first porosity level, and a pad joint-facing surface on an opposite side of the transverse portion from the pad bone-facing surface, with a second, lower porosity level. The bone engagement surface may be formed via a first manufacturing process selected from the group consisting of forging, milling, and casting. The bone engagement pad may be formed via an additive manufacturing process.
