Abstract
Embodiments are directed to bone-joining or bone-bridging intervertebral implants with an inner channel-type structure of channels, which extend parallel from a bone contacting-surface of the implant to the inside of the implant, whereby the channels are connected by lateral openings.
Claims33
Intervertebral implant, wherein the implant comprises:
- two surfaces for contacting two vertebral bodies, an inner structure;
- and an outer sheath which surrounds the inner structure;
- wherein the inner structure comprises a channel structure that is formed by a plurality of vertical channels running along a longitudinal axis of spinal column and a plurality of horizontal channels running horizontally from one side to opposite side of the implant, wherein each vertical channel is connected by a horizontal channel with at least two openings with adjacent vertical channels, the openings extending continuously from one bone-contacting surface to the opposite surface in form of cuts;
- wherein the openings are located either only in lateral areas or only in anterior-posterior areas of channel walls.
1 more element
wherein the outer sheath surrounds the inner structure partly at two opposite sides.
An intervertebral implant comprising:
- two surfaces for contacting two vertebral bodies, an inner structure, and an outer sheath which surrounds the inner structure, wherein the inner structure comprises a channel structure that is formed by a plurality of vertical channels running along the longitudinal axis of the spinal column and a plurality of horizontal channels running horizontally from one side to the opposite side of the implant, wherein openings between the vertical channels are point-shaped, punctiform, circular, cylindrical, oval or wedge-shaped and the openings extend continuously from one bone-contacting surface to the opposite surface in the form of cuts and wherein the openings are located either only in the lateral areas or only in the anterior-posterior areas of channel walls.
An intervertebral implant comprising:
- two surfaces for contacting two vertebral bodies, an inner structure, and an outer sheath which surrounds the inner structure, wherein the inner structure comprises a channel structure that is formed by a plurality of vertical channels running along a longitudinal axis of spinal column and a plurality of horizontal channels running horizontally from one side to opposite side of the implant, wherein the inner structure of the implant permits micro-movements due to wedge-shaped or oblique openings in form of longitudinal cuts along channel wall.
