The present disclosure provides a provisional tibial prosthesis system for a set of prosthetic knee joints for implantation in a natural knee, the provisional tibial prosthesis system including a bearing component and a bearing support, the spacing of the bearing component from the bearing support is adjustable to allow for representation of a variety of different sized final tibial prostheses. In this system, only one provisional bearing component corresponding to each level of constraint is needed and shims are used to adjust the spacing of the bearing component from the beating support. The shims are slidably insertable between the bearing component and the bearing support in an anterior/posterior direction to allow for adjustment of the spacing of the bearing component from the bearing support. The number of provisional components needed during knee surgery is reduced and adjustment of the system only requires the knee joint to be distracted by a distance equal to the height of a particular shim.

A revision-implant receiver (18) is provided for supporting an implant (20) of a revision joint replacement (10). The revision-implant receiver (18) comprises a first receiver element (22) and a second receiver element (24). The first receiver element (22) and the second receiver element (24) are engaged with each other via a hinge element (26).

A humeral implant component connectable to another humeral implant component, the humeral implant component comprising: a longitudinal axis, a first end and a second end, the first end and the second end opposing each other along the longitudinal axis of the humeral implant component, and an interface part for connecting the humeral implant component to the other humeral implant component, wherein the interface part is tapered along the longitudinal axis in a direction from the second end to the first end, the interface part being engageable with a tapered interface part of the other humeral implant component to form a tapered connection between the humeral implant component and the other humeral implant component, wherein the humeral implant component further comprises a through hole extending along the longitudinal axis for locking the tapered connection by a longitudinal fastener.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.

An interbody implant comprises one or more elongate members that have superior and inferior surfaces with a height, and medial and lateral surfaces having a width. The height is set so the implant fits into the intervertebral space. The width is less than the height. The interbody implant has a first configuration, a second configuration, and a third configuration. The interbody implant is inserted into the intervertebral space in the first configuration such that medial and lateral surfaces contact the vertebral bodies, and the interbody implant is then actuated into the second configuration such that superior and inferior surfaces engage the vertebral bodies. Actuation of the implant from the first configuration to the second configuration distracts the vertebral bodies. The implant is actuated into the third configuration where the width of the implant is greater than width of the implant in the first or the second configuration.

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.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

This disclosure provides vertebral implants, fastening devices for vertebral implants, and implant instrumentation, and various combinations thereof. In some embodiments, the implant comprises a peripheral wall extending according to a vertical axis between upper and lower surfaces of the implant, with each such surface configured to be placed in contact with a vertebral structure, respectively, at the top and the bottom of the vertebral segment replaced by the implant. Some embodiments comprise fastening means, deployment of which anchors the implant in the lower and upper vertebral structures. Some fastening means may be deployed by sliding parallel to the vertical axis of the implant, and may comprise a plate with at least one part remaining in contact with the peripheral wall of the implant when deployed and a pointed end projecting from one of the upper and lower surfaces of the implant to enter a vertebral structures on completion of deployment.

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.
