Abstract
A bone implant and the method of manufacturing thereof, the bone implant, in particular an inter-vertebral implant, made of a radiation-permeable material having a circular-shaped hollow body with a sleeve. The inter-vertebral implant defining a surface and comprising a front section, a back section, and two lateral sections defining a central axis. The hollow body is subdivided by at least two partitions running essentially parallel to the central axis and which connect the front section to the back section. The surface of the bone implant has surface irregularities of at least 2 μm, and the at least two partitions have at least one perforation.
Claims27
An inter-vertebral implant made of a radiation-permeable material having a substantially circular-shaped hollow body with a sleeve, the inter-vertebral implant defining a surface and comprising:
- a front section, a back section, and two lateral sections defining a central axis,
- wherein the hollow body being subdivided by at least two partitions, the at least two partitions running essentially parallel to the central axis and connecting the front section to the back section and the at least two partitions have at least one perforation, and
- wherein the perforations of the partitions are at least partially filled with an X-ray-opaque filler material.
An inter-vertebral bone implant, made entirely or in part of a radiation-permeable material comprising a substantially circular-shaped hollow body with a sleeve, the intervertebral implant defining a surface and comprising:
- a front section, a back section, and two lateral sections defining a central axis, the hollow body being subdivided by at least two partitions, the at least two partitions running essentially parallel to the central axis and connecting the front section to the back section, the at least two partitions trussed together by a cross strut,
- wherein the at least two partitions have at least one perforation, and
- wherein the perforations of the partitions are at least partially filled with an X-ray-opaque filler material.
An inter-vertebral implant, made entirely or in part of a radiation permeable material defining a surface, the implant comprising:
- an outer sleeve defining a central chamber for receiving a filler material and configured for permitting new bone growth therethrough, the outer sleeve having a front section, a back section, and first and second lateral sections;
- a first partition and a second partition, the first and second partitions connecting the front section to the back section so as to subdivide the central chamber, the first and second partitions spaced relative to one another and formed with the outer sleeve so as to define superior and inferior support areas for engaging and supporting endplates of inter-vertebral bodies adjacent said implant;
- a plurality of perforations in the outer sleeve and the first and second partitions, the outer sleeve perforations in fluid communication with the central chamber for receiving and fixing the filler material with respect to the implant, and
- wherein a cross brace is located between the first and second partitions for laterally supporting the first and second partitions and at least a portion of the surface has surface irregularities for fixation of the new bone growth.
