A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.

The invention relates to a method and a device for producing an implant, wherein a natural bone microstructure of a natural bone region is detected (S1), an implant region in the natural bone region is marked (S2), the detected bone microstructure in the marked implant region is analysed to determine reproduction parameters (S3), and on the basis of the determined reproduction parameters, an artificial microstructure for producing the implant is created (S4).

Multi-hooded enarthrodial joint implant has a ceramic articulating cup including a ceramic head-receiving cup having an articular surface upon which a head of a joint can articulate, and which, in general, has a margin generally about a hemisphere more or less and at least two hoods that are marginally extended continuations of superior one-half or so of cup containment of a sufficient magnitude to reduce an overall dimension of socket outlet to less than a hemisphere, which can embrace and contain the head. The head is made of ceramic and has a truncated generally circular cross section, a truncated surface with a feature for attachment of the stem, and an opposing articular surface for articulation against the articular surface of the ceramic head-receiving cup. As an ensemble, the cup is combined with the head, typically with a stem, for a total joint implant.

An orthopaedic implant includes an implant body having a first surface, a second surface opposite the first surface, and a cavity formed therein that extends through the first surface and the second surface. The implant body has a third surface with at least one first opening formed therethrough to the cavity. The at least one first opening includes an outer portion having an outer diameter and an inner portion having an inner diameter. The implant includes a load bearing member including a porous material held within the cavity. The outer portion of the at least one first opening is configured to couple to a tool for receiving, from the tool, a material agent, and the inner portion of the at least one first opening is configured to couple to a plug for preventing the material agent from exiting the porous material via the at least one first opening.

A prosthetic system that includes a prosthetic implant acrd a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining a channel between the pair of components.

Spacerless artificial disc replacements (ADR) are disclosed. One preferred embodiment includes two saddle-shaped components to facilitate more normal spinal flexion, extension, and lateral bending while limit axial rotation, thereby protecting the facet joints and the annulus fibrosus (AF). Either or both of the superior and inferior components are made of a hard material such as chrome cobalt, titanium, or a ceramic including alumina, zirconia, or calcium phosphate. The articulating surfaces of the ADR are also preferably highly polished to reduce friction between the components. Metals, alloys or other materials with shape-memory characteristics may also prove beneficial.

An expandable interbody device for placement between adjacent vertebrae having an upper structure, a lower structure and a screw mechanism, wherein actuation of the screw mechanism moves the upper and lower structures between a collapsed configuration and an expanded configuration. A deployment tool couples to the expandable interbody device for positioning the device between adjacent vertebrae, actuating the screw mechanism and delivering a material to a chamber of the expandable interbody device.

A total knee prosthesis to be implanted in a human patient includes a femoral element having a longitudinal axis, a tibial plateau having a longitudinal axis and a mobile plate. The mobile plate is interposed between the femoral element and the tibial plateau to form two joints with them wherein: a) the surfaces of mutual friction of the femoral element with the mobile plate and the surfaces of mutual friction of the tibial plateau with the mobile plate are entirely constituted by one and the same massive ceramic material; and b) the mobile plate includes two condylar bowls, and the femoral element includes two condyles, the condyles and the condylar bowls each having surfaces of mutual friction spaced apart from each other by a distance smaller than 100 m when the longitudinal axes of the femoral element and the tibial plateau form an angle of 0 to 75.

A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.
