A system and method for forming a medical implant using a printing device. The printing device includes a print head having a heated nozzle, a heated build plate for receiving the printed material thereon, and a reflective plate having an active heater. A method for forming a medical device includes extruding a printing material by contiguous deposition to form a porous object having a lattice-like structure. The medical device, such as a spinal implant, may have interconnected pores and different regions, each having a different porosity for encouraging bone growth therein. The printed medical implant may be designed to be patient-specific, customized, and printed on-demand.

The present invention relates to the diagnosis and treatment of joint-related diseases, in particular osteoarthritis. Based on the analysis of the microarchitecture, such as microchannels, of the subchondral bone, the present invention provides methods for evaluating the health state of a joint as well as determining whether a joint is prone to develop or has already developed a disease correlated to joint and cartilage destruction. The invention further provides for membranes and other implants mimicking healthy subchondral bone structure suitable for promoting regeneration of joint structure and function.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

The present disclosure in one aspect provides a surgical implant comprising an upper bone contacting surface comprising a plurality of irregularly shaped pores having an average pore size, where the pores are formed by a plurality of struts, a lower bone contacting surface comprising a plurality of irregularly shaped pores having an average pore size, wherein the pores are formed by a plurality of struts; and a central body comprising a plurality of irregularly shaped pores having an average pore size, wherein the pores are formed by a plurality of struts, wherein the average pore size on the upper and lower bone contacting surfaces is different than the average pore size on the central body.

A bone graft delivery system and method for using same to deliver graft material into a surgical site. The method includes the steps of providing a hollow tube configured to receive the graft material, releasably attaching an implant to a distal end of the hollow tube so as to communicate with at least one opening in the distal end of the hollow tube, the implant being configured to receive the graft material delivered through the hollow tube; placing the implant within the surgical site; advancing the graft material through the hollow tube; conveying graft material through the hollow tube into an interior of the implant, whereby the implant is at least substantially filled with the graft material; and discharging the graft material through at least one opening in the implant into the surgical site, whereby the surgical site is at least substantially filled with the graft material.

A modular augment cone system and methods of implanting the modular augment cone system. The system includes a main body cone a first cutout in the cone wall, and including a proximal end, a distal end, and a cone wall extending between the proximal and distal ends. A portion of the cone wall proximal to the first cutout includes an attachment feature. A first augment cone is positionable in the first cutout, the first augment cone including an attachment feature configured to mate with the attachment feature of the cone wall to attach the first augment cone into the first cutout. The main body cone can include a second cutout in the cone wall. In such systems, the modular augment cone system can include a second augment cone configured to mate with an attachment feature of the cone wall to attach the second augment cone into the second cutout.

An expandable augment system is provided for use with an acetabular cup. The expandable augment system can include an expandable augment module that is adjustable in size and that can be adjusted incrementally between a fully collapsed state and an expanded state. A first portion of the expandable augment module is attachable to an outer surface of an acetabular cup and a second portion of the expandable augment module is attachable to bone or to a fixed augment module (e.g., a fixed angle augment module) that is attached to bone and interposed between the adjustable augment module and bone.

Augment element for knee prosthesis, comprising a metal body of a substantially truncated conical shape configured to be inserted into a bone extremity and having an outer surface comprising a metal trabecular surface. The metal body being hollow with an axial through-cavity defining a plurality of substantially annular transversal sections. The metal body is inclined in a direction of inclination, so as to define at least one eccentricity between a first transversal section at a first end of the axial through-cavity and a second transversal section at a second end of the axial through-cavity. The augment element further comprises a plurality of through-slits in the metal body, open from the first end up to an intermediate portion on the metal body, wherein the plurality of through-slits is configured for a radial compression of the metal body, locally reducing a circumference of the substantially annular transversal sections during insertion of the augment element, and increasing a press-fit towards a bone portion.

In some implementations, the interbody implant may include an anterior side, a posterior side, a cephalad side, a caudal side, a right side, and a left side. In addition, the interbody implant may include a proximal end and a distal end. The interbody implant may include a mesh having a first set of pores having a first diameter based on a first relationship to a first locus and a second set of pores having a second diameter based on a second relationship to the first locus. Moreover, the interbody implant may include where at least one of the anterior side, posterior side, left side, right side, cephalad side, and caudal side may include the mesh.

Disclosed herein is a spinal implant with a solid frame and a porous inner layer. The implant may have a cavity defined by the porous inner layer. The solid frame may have one or more ribs extending from a medial wall to a lateral wall. The thickness of the porous layer may vary relative the thickness of the solid frame at various locations. An inserter to place a spinal implant and a method to perform same are also disclosed.
