The invention relates to an augmentation device comprising an annular cone surrounding a channel extending through the cone from a proximal cone end to a distal cone end of the cone. The invention further relates to an augmentation system comprising such an augmentation device and an applicator, as well as an implantation method of an augmentation device using such an augmentation system.

A method for removing a stem portion of an orthopedic implant from a bone comprises exposing an implanted orthopedic implant having a body portion, a stem portion interconnected to the body and a porous metal section forming an interconnection between the body and the stem portion. A cutting tool is mounted on a holder connected to an exposed surface of the orthopedic implant. The porous section is aligned with the cutting tool mounted on the holder. The entire porous section is cut by moving the cutting tool therethrough in a direction transverse to the stem portion axis. The implant body portion is then removed and then the stem portion is removed from the bone. The cutting tool may be a saw or chisel which may be mounted on a guide fixed to the body portion.

An artificial replacement disk assembly comprised of a core in between two endplates. The endplates have outer surfaces that match the surface morphologies of the corresponding vertebral endplates. The endplates may have textured inner surface to form a strong fusion with the core during the fabrication process. The thick solid endplates strongly fused to the core create a very resilient implant. Gripping structures on the endplates may permit easy manipulation of the assembly during surgical procedures.

The present disclosure provides zirconium powder particles comprising pure zirconium powder particles with an oxide layer ranging from 0.05 to 5 microns in thickness and/or zirconium alloy powder particles with an oxide layer ranging from 0.05 to 5 microns in thickness. In some embodiments, the zirconium powder particles may be spherical particles, the zirconium powder particles may range from 5 microns to 125 microns in diameter, and/or the zirconium powder particles may have a median particle size ranging from 25 to 70 microns in diameter. The present disclosure further provides methods of producing medical implants or medical implant components by a process that comprises selectively applying energy to such zirconium powder particles to build the medical implants or the medical implant components. In some embodiments, the methods comprise repeatedly forming a layer of zirconium powder particles and irradiating the layer of zirconium powder particles with an energy source.

A device including a delivery port and a method of delivering a material via a delivery port is disclosed. The device includes a body extending between a proximal surface and a distal surface. The body is sized and configured to be coupled to an anatomical structure at an implantation site. A first inlet port is formed in a distal surface of the body and is sized and configured to receive a first material. A first outlet port is formed in the proximal surface of the body. The first outlet port is coupled to the first inlet port by a first fluid path defined by the body and the first outlet port is sized and configured to provide the first material to a first predetermined location when the body is coupled to the anatomical structure.

A computer-generated component file for fabricating an orthopedic implant is prepared. First and second select sections of an initial implant model of a computer-aided design model are set to first and second model porous sections. A remaining section of the initial implant model is left. All regions defining the first and the second select sections are spaced not more than a preset distance from a patient-specific bone model of the computer-aided design model as measured uniformly. The first and the second model porous sections are merged with a remaining section of the initial implant model to form at least a portion of a final implant model. The final implant model is stored in a component file configured to be accessed by a computer-aided manufacturing machine for use in fabricating the orthopedic implant. At least a portion of the orthopedic implant corresponds to the final implant model.

A bellows shaped spinal implant, comprising an upper plate, a lower plate and a bellows shaped shell extending between and joining the upper and lower plates. The bellows shaped shell is formed of titanium or an alloy comprising titanium and includes a wall extending therearound that defines a hollow interior. The wall has a thickness in the range of 0.5 mm to 1.0 mm to provide for radiographic imaging through the wall. The wall is angled or curved inwardly or outwardly between the upper and lower plates to provide stiffness mimicking the stiffness properties of a similarly sized polyetheretherketone (PEEK) implant. The upper and lower plates each comprise porous contact regions including a three-dimensional gyroid lattice structure defined by a plurality of struts and pores in communication with the hollow interior. The outer surfaces of at least a portion of the struts may comprise a laser ablated textured surface.

An intervertebral cage with an outer frame, an open inner core region and a porosity gradient within the outer frame is provided. The outer frame includes a posterior wall, an anterior wall, a pair of side walls extending between the posterior wall and the anterior wall and the porosity gradient may comprise at least one of: a decreasing average pore diameter in a direction from an outer surface to an inner surface of at least one of the pair of side walls; an increasing average pore diameter in a direction from an outer surface to an inner surface of at least one of the pair of side walls; a decreasing average pore diameter in a direction from an upper surface to a lower surface of at least one of the side walls; and an increasing average pore diameter in a direction from an upper surface to a lower surface of at least one of the side walls.

A bone graft system includes a two-dimensional mesh sheet sized and shaped to, when folded along fold lines, form a three-dimensional graft containment structure configured to be packed with a bone graft material for placement within a target area of a bone, the mesh sheet including a first end flap connected to a remaining portion of the mesh sheet via a first fold line and a second end flap connected to the remaining portion of the mesh sheet via a second fold line, a third fold line extending from the first fold line to the second fold line so that the remaining portion is configured to be wrapped around folded first and second end flaps to form the graft containment structure, the first and second end flaps substantially corresponding to a profile of the target area of the bone.
