An expandable implant may include a superior endplate and an inferior endplate hingedly coupled together. The superior endplate may have at least one track extending in a proximal-to-distal direction and an inferior endplate may have at least one track extending in the proximal-to-distal direction. The implant may further include a proximal plate having a superior engagement surface and an inferior engagement surface. At least one shim may be disposed within the at least one tracks of the superior endplate and interior endplate, and the at least one shim may define an angle of inclination between the superior endplate and interior endplate. The at least one shim may be insert between the superior and inferior endplates to effectuate expansion and angulation. In various embodiments, the superior endplate may be supported by the superior engagement surface and the inferior endplate may be supported by inferior engagement surface.

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.

Methods for securing a intervertebral cage to one or more levels of the spine with fixation. The fixation, which is typically a staple, is intended to be driven perpendicular to the proximal face of the cage and in-line with the inserter. After the cage is placed and positioned according to surgeon preference, a single piece fixation clip is then deployed and fixed in a manner that produces a zero-profile device.

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.

An orthopaedic prosthesis system and associated instrumentation is disclosed. The system includes femoral and tibial components configured to be used in a number of different implanted configurations. The instrumentation is configured to facilitate preparation of the bones and selection of the implant configuration. A method of using the system is also disclosed.

A system of prosthetic implants for a total knee replacement procedure is provided. The system includes a tibial component of a knee joint implant, a tibial insert configured to be positioned against the superior side of the platform of the tibial component, a first femoral component of a knee joint implant, and a second femoral component of a knee joint implant.

A cement restrictor inserter instrument (130) comprises an inserter (131) having a handle (132) at a proximal end, a cement restrictor attachment formation (137) at a distal end for releasably attaching a cement restrictor (150), a shaft (136) extending from the proximal end to the distal end and a stop (138) on the shaft and between the proximal end and the distal end; and a body (140) having a shape corresponding to the shape of an orthopaedic prosthetic implant, a spacer (142), a visible depth guide feature (190) and a releasable attachment mechanism by which the body is releasably attachable to the shaft, and wherein the spacer is configured to position the visible depth guide feature at a fixed position relative to the inserter when the spacer abuts the stop corresponding to a target cement restrictor position when the visible depth guide feature is aligned with a feature of a bone of a patient in which the cement restrictor is to be inserted.

In a tibial component, an engagement mechanism configured to engage a tibial block and a tibial tray includes a recessed portion that is disposed in a lower surface, is non-penetrating, and includes an overhanging portion protruding inward more on an opening side than on a bottom portion side in at least a part of an inner wall; and a projecting portion that protrudes from the tibial block to the lower surface side, and includes a protruding part configured to engage with the overhanging portion.

A multifunctional spacer for knee surgery is described comprising a main body configured for use with a single femoral condyle and having an anterior portion of a first height and a posterior portion of a second height, wherein the second height is greater than, equal to or less than the first height. In addition, the anterior portion and/or the posterior portion is provided with an attachment mechanism for selective attachment of a height adjuster.

A shoulder arthroplasty kit includes a combination sizer and guide device with a base portion including a rim configured to be positioned against a resected surface of a humerus. A cavity which is configured to receive a mounting portion of a humeral base component extends proximally from the base portion, the cavity. The combination sizer and guide device includes a convex outer surface which replicates at least a part of an outer bearing surface of a humeral head component. A bore which is perpendicular to the distal plane extends between the cavity and the convex outer surface. The kit further includes a guide pin with a maximum diameter sized to fit within the bore such that the guide pin is guided by the bore during insertion of the guide pin into the resected surface of the humerus.
