A method of forming a shoulder prosthesis includes resecting an end portion of a humerus to form a resected end of the humerus and a resected portion separated from the humerus, the resected portion having an outer convex surface and an inner surface. The inner surface of the resected portion is processed to include a concave articular surface. The outer convex surface of the resected portion is implanted in the resected end of the humerus. An implant having a convex articular surface is secured to a glenoid. The concave articular surface of the resected portion is articulated with the convex articular surface of the implant.

Provided is a structure of a porous spinal implant including a cage body inserted between adjacent vertebral bodies and divided by an upper surface, a lower surface, a left surface, a right surface, a front surface, and a rear surface, a plurality of vertical pores formed on the upper surface and the lower surface of the cage body, and a plurality of horizontal structures stacked on the left surface and the right surface of the cage body, wherein the plurality of vertical pores and the plurality of horizontal structures are each formed in a pattern that repeats in up-down, left-right, and front-rear directions. The structure of a porous spinal implant is capable of reducing strength of a cage body close to that of a vertebral body.

A medical honeycomb structure lacking at least a portion of an outer peripheral side wall of a honeycomb structure that includes a plurality of through-holes extending in one direction, wherein sites lacking the outer peripheral side wall have a plurality of grooves, and have a plurality of planes including distant surfaces of groove side walls flanked by the grooves.

Methods and apparatus for delivering a sheet-like implant to a target site including a means of deploying and orienting the sheet-like implant within the body.

A medullary rod has a peripheral wall defining the outer shape of the medullary rod, and inwardly delimiting a hollow space. The medullary rod also has a plurality of first partitions. The first partitions are generally parallel to one another, extend between the inner side of the medullary rod located along the inner edge of the long bone after implantation, and the outer side of the medullary rod located along the outer edge of the long bone after implantation. Each of the first partitions is integral with the peripheral wall at these inner and outer sides of the medullary rod.

A talar implant having at least one body section, at least one mesh section and at least one solid section extending down from the body section. The solid section having at least one point end. Further disclosed is a kit for inserting a talar implant including at least one tibial guide, at least one talar guide, and at least one impactor for inserting the talar implant into a talus. In addition, a method for implanting a talus implant is disclosed. The method can include identifying a damaged area on a talus, projecting a missing damaged area on a contralateral joint and printing an implant based upon a mirror image of a portion of the contralateral joint. The method can include applying at least one guide, removing at least a portion of a damaged region of the talus, inserting the talar implant and setting the talar implant in the talus.

There is disclosed a talus implant comprising a base having at least one hole and at least one pin. There is also a top comprising at least one hole and at least one pin, wherein the top is configured to be inserted into the base. At least one embodiment comprises a tibial implant comprising at least one post and at least one base coupled to the at least one post. Additionally, there is at least one pad coupled to the at least one base, wherein the at least one pad is selectively insertable into and removable from the at least one base. A method for fabricating a talus and tibial implant is disclosed and also a method for inserting a talus implant and a tibial implant into a patient having a damaged talus joint.

Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.

The present invention relates to a vertebral system comprising a vertebral implant (2) and a plurality of inserts, said implant being designed to be implanted in a vertebral segment composed of at least two vertebrae and including a body (20) the walls whereof delimit a cavity (23) leading to the outside of the body (20) through at least one opening in at least one of said walls, at least one passage (21) passing through the implant (2) from the periphery to an upper or lower surface to receive a bone-anchoring device (1) capable of anchoring the implant (2) in at least one of said vertebrae, the system being characterized in that it includes at least two inserts selected from among the following inserts: at least one graft insert (3, 3A, 3B, 4, 5A, 5B, 6A, 6B, 6C, 6D, 202, 250) capable of being colonized by bone tissue and/or receiving at least one bone tissue graft and/or at least one substitute; and/or at least one bone-anchoring insert (210) comprising said passage (21) capable of receiving said bone-anchoring device (1).

Provided is an implant for restoring the mobility of an articular end of a bone. The implant includes a framework having a first face and a second face opposite the first face, the framework is defined by a plurality of free volumes formed by a grating, where the grating includes a first series of bars extending through the framework from the first face to the second face, and a second series of bars extending through the framework from the first face to the second face, wherein the second series of bars are parallel to one another, and spaced apart in pairs, where the bars have ends along the second face that are bevelled.
