Abstract:
Die Erfindung betrifft eine Hüftgelenkspfanne (1) für eine Hüftgelenksprothese mit einer inneren Kavität (2) und einer rückseitigen knochenzugewandten Mantelfläche (3). Damit die Hüftgelenkspfanne (1) zementfrei implantiert werden kann, wird vorgeschlagen, dass die Mantelfläche (3) zumindest in Teilbereichen porös und osseointegrativ ausgebildet ist und die Hüftgelenkspfanne (1) ausschließlich aus einem keramischen Material besteht.
Abstract:
Systems, devices and methods for fusing both sacroiliac joints of a patient using a long implant are provided. The method can include inserting a guide pin through the first ilium and across the first SI-Joint, through the sacrum and above the SI foramen, across the second SI-Joint, and through the second ilium; forming a first rectilinear cavity through the first ilium and the first SI- Joint; forming a second rectilinear cavity through the second ilium and the second SI- Joint, wherein the first rectilinear cavity and the second rectilinear cavity are aligned; and inserting an implant through the first cavity, across the first SI-Joint, through the sacrum, across the second SI-Joint, and through the second cavity.
Abstract:
An intervertebral implant comprises a first component and a second component. A first arm extends between a first end and a second end. A second arm extends between a first end and a second end. The first ends of the arms are engageable with the first component. An actuator is disposed within the second component and includes a first member and a second member. The members are configured for axial translation relative to the actuator. The first member translates in a first axial direction and is engageable with the first arm and the second member translates in a second axial direction and is engageable with the second arm such that the arms move the first component and the second component between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.
Abstract:
The present invention relates to a fixture for insertion into a human bone. The fixture comprises a core from which a surface structure projects. At least one channel is provided in the surface of the surface structure and has an extension in a direction towards the top of the surface structure. The depth of the channel is smaller than the height of the surface structure.
Abstract:
A spinal implant of hybrid construction. The implant includes both porous and radiolucent elements. In this manner, the implant allows for substantial fusing of vertebrae while simultaneously allowing for useful follow-on evaluations through imaging. Furthermore, in spite of the potentially differing material character of the porous and radiolucent elements, they may nevertheless be coupled together in an interlocking configuration such that the implant exhibits the behavior of a single unitary device.
Abstract:
A device (30) for promoting fusion of first and second vertebrae, comprises a first solid region formed of non-porous polyetheretherketone (PEEK) (46) and a first porous region (48, 50) including a porous PEEK architecture. The first porous region is bonded to the first solid region.
Abstract:
An implant for bone replacement and attachment in an animal's body including, a structural portion having an outer porous surface, a ceramic material applied to the porous surface of the structural portion, characterised in that the thickness of the ceramic material as applied utilizing pulsed pressure MOCVD is such that at least some of the pores of the porous surface are not completely closed.
Abstract:
An intervertebral prosthetic disc is disclosed. Hie intervertebral prosthetic disc can be installed withai an intervertebral space between adjacent first and second vertebrae. The intervertebral prosthetic disc can include a first component, that, is configured toengage the first vertebra, a second component that is configured to engage the second vertebra, and at least one expandable motion Ii miter. Further, the expandable motion limiter can be configured to move from a deflated position to at least one inflated position.
Abstract:
The invention concerns a method for obtaining a metal implant for open porosity tissue support and/or replacement, characterized in that it includes the following steps: (i) selecting a mold, (ii) arranging in the mold a solid metal core (7), (iii) filling the volume of the mold (1) still available with the powder of microbeads (3), (iv) integrating the microbeads with one other as well as with said at least one solid core (7) by electrical discharge machining.
Abstract:
A surgical implant containing two opposing shells (20, 40), a central body (60) disposed between the shells, and a flexible sheath (70) extending between edges of the opposing shells. The sheath is formed from a composite structure comprising a flexible material (1000, 1003) and a resistant material (1002) that provides for resisting at least one predetermined type of relative directional motion.
