Arthroplasty implant systems and methods are provided for restoring the functionality of a joint. The arthroplasty implant systems may include a threaded cup having a cylindrical shaped body and a flange. A thread may be provided on the cylindrical shaped body. The thread is configured to engage a bone, and the flange is configured to engage a cortical rim of the bone.

Arthroplasty implant systems and methods are provided for restoring the functionality of a joint. The arthroplasty implant systems may include a modular threaded cup having a cylindrical shaped body and a flange that is removably connectable to the cylindrical shaped body. A thread may be provided on the cylindrical shaped body. The thread is configured to engage a cortical and/or cancellous bone of a bone, and the flange is sized to engage a cortical rim of the bone.

A reverse shoulder prosthesis system is provided. The system can include a the convex surface of the glenosphere and the concave surface of the humeral socket. The convex surface, a humeral socket can have a concave surface, and a cup is positioned between cup can be moveable relative to the glenosphere and to the humeral socket.

Prosthesis for a shoulder joint including a humeral component equipped with a stem, a head component and connection or articulation means of the humeral component with the head component, wherein the prosthesis according to the invention can be used both as a conventional prosthesis and as a reverse-type prosthesis.

A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.

A component of an artificial joint according to an exemplary aspect of the present disclosure includes, inter alia, a hollow tube including bone ingrowth material. Further, the hollow tube is selectively expandable. The bone ingrowth material allows the component to become biologically fixed to adjacent bone. Further, expansion of the hollow tube increases friction between the hollow tube and the adjacent bone, which increases stability.

An inclination guide for use with an implant insertion tool during a surgical procedure includes a unitary body having a clip configured to be coupled to a mounting surface of the implant insertion tool, an elongated riser extending from the clip, and an elongated indicator extending from the elongated riser to a distal end. Such a design allows for an inexpensive and lightweight inclination guide that may be easily and quickly adjusted after assembly.

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.

Disclosed herein is a humeral head trial, a system for humeral trialing, and a method for removing a humeral head trial from a humeral stem. The humeral head trial may include a first portion, a second portion, and a post extending from the second portion. The first portion may define a convex articular surface with a movable surface substantially flush with the convex articular surface. The post may define a first length in a first configuration and a second length in a second configuration. The first length may be greater than the second length. The post may change from the first configuration to the second configuration by moving the movable surface with respect to the convex articular surface.

An expandable intervertebral fusion implant, including an inferior component, including a first top surface, a first bottom surface, a first end including a first worm rotatably arranged therein, the first worm including a through-hole operatively arranged to allow material to be injected therethrough and into a central hole of expandable intervertebral fusion implant, and a second end including a second worm rotatably arranged therein, a superior component, including a second top surface, a second bottom surface, a third end, and a fourth end, and a first expansion mechanism including a first screw, the first screw including a first bottom end connected to the inferior component and a first top end connected to the superior component, wherein as the first worm is rotated in a first circumferential direction, the first screw rotates in a second circumferential direction and the superior component is displaced relative to the inferior component.
