Disclosed are devices for the fixation and support of vertebrae, particularly adjustable spinal implant devices.

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.

Disclosed is a medical device comprising a porous structure, wherein a configuration of the porous structure varies in dependence on a load applied to the porous structure, such that the porous structure has a first configuration when the load is of a first magnitude, and has a second configuration when the load is of a second magnitude greater than the first magnitude. The porous structure comprises a first surface portion and a second surface portion. The first surface portion is disengaged from the second surface portion when the porous structure has the first configuration, and is engaged with the second surface portion when the porous structure has the second configuration.

Provided is a glenoid implant system that includes a tray component that includes a bone-facing surface and a bearing-facing surface on opposite side of the bone-facing surface; and a bearing component that includes an articulating surface that is generally concave and a back side on opposite side of the articulating surface that is generally convex, wherein the articulating surface is configured for engaging a convex humeral head and the back side is configured for engaging the bearing-facing surface of the tray component thus enabling the bearing component to slide about on the tray component while the convex humeral head articulates against the articulating surface.

The present disclosure relates to a spinal implant for insertion between two adjacent vertebrae. The spinal implant includes a frame sized to be inserted between the two adjacent vertebrae. The spinal implant also includes a lattice structure disposed at least partially within the frame and exposed on at least one side of the frame to permit bone growth into the lattice structure. The lattice structure comprises a magnesium phosphate material.

A device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress/strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient.

A surgical fastener manipulation tool in accordance with embodiment of the present invention is useful by a surgeon to place fasteners such as threaded screws. The surgical fastener manipulation tool selectively engages a mating structure of fastener for securing the fastener thereto. Thus, advantageously, the surgical fastener manipulation tool can be used for placing such fasteners and/or can be used for extracting (i.e., removing) such fasteners. The ability to extract a fastener (e.g., a threaded bone screw) with the same tool used for placing it is highly beneficial due to time savings during a surgical procedure and is advantageous with respect to prior art fastener manipulation tool configurations that require placement and extraction tools to be differently configured.

A non-patient specific implant for neuroplastic surgery is provided. The non-patient specific implant includes a three-dimensional mesh. The three-dimensional mesh comprises titanium. The three-dimensional mesh is pre-folded. The three-dimensional mesh is configured to replace a space for a hard tissue and/or a space for a soft tissue. The three-dimensional mesh has a three-dimensional triangular shape.

Spinal implants, spinal implant systems, and methods for inserting spinal implants are provided. The implants can be implanted in an intervertebral space between adjacent superior and inferior vertebrae. The implant includes a superior implant surface having one or more superior positioning grooves configured to receive a corresponding superior positioning rail and an inferior implant surface having one or more inferior positioning grooves configured to receive a corresponding inferior positioning rail when the implant is implanted in the intervertebral space.
