An adjustable orthopedic implant can include a neck assembly, a stem assembly, and a drive assembly having a first portion coupled to the neck assembly and a second portion coupled to the stem assembly. The drive assembly can include an actuator configured to rotate in response to the actuation signal, and a threaded rod coupled to the actuator and configured to rotate in response to rotation of the actuator. The threaded rod can engage a threaded receptacle of the stem assembly such that rotation of the threaded rod in a first direction urges the neck assembly and the stem assembly closer together, and rotation of the threaded rod in a second, opposite direction urges the neck assembly and the stem assembly further apart.

An Apparatus for an Anatomical Prosthesis of the Temporomandibular Joint which includes a polymeric centralizing device for the pyriform condyle in the concavity of the polymeric temporal section that joins the condyle to the body of the mandibular fixture, in a stable and secure way, using a frictional interference Cone-Morse-Connection, as well as a flat part in the center of the cavity of the temporal section and posterior edges of specific dimensions, which make the fixture of the junction of the mandibular section and the temporal section more secure and allows freedom of centric movement.

Modular endoprosthesis for at least partial replacement of a tubular bone, comprising, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece comprising a support body with a neck part arranged on the medial aspect thereof. Said module components being able to be coupled to each other and released from each other along a longitudinal axis of the shaft. The end piece has at least two different surface configurations on its support body, namely a closed surface (6′) on a medial aspect, and a porous configuration of the surface on the opposite, lateral aspect. The latter permits and positions the adhesion of muscle tissue, specifically without suturing. The muscle trauma caused by suturing, and the peak loads that occur at the respective suture points, can thus be avoided by virtue of the invention, by means of the location-specific direct adhesion of the muscle. It is thus possible to achieve quicker and reliable mobilization of the patient, and this with a reduced risk of complications.

An expandable vertebral body implant, and methods of assembly and using the implant. The vertebral body implant includes a body with a first end and a second end, a rotating member rotatably coupled to the first end of the body, wherein an end includes a plurality of first notches inset into the rotating member, an extension member moveably coupled to the rotating member, and a locking member positioned on an interior of the body. Methods for assembling and using the vertebral body implant are also disclosed.

The present invention relates to a glenoid component (100, 600, 800, 1000, 1200) for shoulder prosthesis, comprising: a glenoid coupling surface (101, 1001), adapted to be fixed to a bone and comprising a first convex portion (102) having a first outer edge (103, 1003) which defines a development plane (104, 1004); a prosthetic coupling surface (105, 1005), opposite the glenoid coupling surface (101, 1001) and adapted to house a second prosthetic component of the shoulder prosthesis, the prosthetic coupling surface (105, 1005) comprising a second portion (106) having a second outer edge (107, 1007) which defines a reference plane (108, 1008); wherein the glenoid component (100, 1000) provides a predetermined offset (109, 809, 1009) between the development plane (104, 1004) and the reference plane (108, 1008), so as to define an increased thickness of the glenoid component (100, 1000) adapted to compensate for a bone deficit. The present invention also relates to a shoulder prosthesis.

A system includes a first implant component and a second implant component. The first implant component is configured to be secured to a bone and includes a plate and a coupler extending upward from the plate and defining a coupler axis. The second implant component is configured to be coupled to the first implant component. The second implant component includes an articulation surface and defines a cavity configured to receive the coupler of the first implant component. The second implant component is couplable to the first implant component at a plurality of rotational orientations about the coupler axis.

This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centred on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.

The present disclosure relates to an implant component (10, 20) having at least one connecting portion (30, 60), the connecting portion being at least partly coated with a Zr coating and the coating having a thickness of 1-20 μm, preferably 1-6 μm. The present disclosure further relates to a modular endoprosthesis comprising an implant component, to the use of a Zr coating to prevent crevice corrosion and/or fretting corrosion, and to the use of an implant component in patients suffering from a metal allergy.

A tibial prosthesis and a knee prosthesis are provided. The tibial prosthesis includes a tibial plateau, a first tibial insert and a second tibial insert. The tibial plateau has a proximal end face defining a mount surface arranged with respect to a first axis. The first tibial insert is disposed on the mount surface rotatably about the first axis. The first tibial insert has a first concave surface centered on the first axis. The first concave surface is distally recessed. The second tibial insert is disposed on the tibial plateau and has a second concave surface extending along an arc-shaped trajectory line that is parallel to the mount surface. The arc-shaped trajectory line is centered on the first axis, and the second concave surface is distally recessed. The first tibial insert and the second tibial insert are arranged independently of each other, and the first tibial insert is located medially to the second tibial insert.
