Abstract
A pseudo arthrosis device may be placed in a disc space to provide support for adjacent vertebrae. The device may have an enclosure formed from a flexible, permeable material. A plurality of elongated members may be packed longitudinally in the enclosure. The elongated members may be compressible and/or flexible. In certain embodiments, elongated members may be solid rods and/or hollow tubes. A plurality of spaced-apart perforations may be formed in solid and hollow elongated members. The enclosure may be placed in an intervertebral space between the adjacent vertebrae such that the elongated members are disposed longitudinally between the adjacent vertebrae. The pseudo arthrosis device may include a tab designed to couple the enclosure to an adjacent vertebrae.
Claims37
A pseudo arthrosis device, comprising:
- an enclosure formed from a synthetic fabric that is permeable, a plurality of elongated members formed of a biocompatible polymer, wherein at least two of the elongated members are packed together longitudinally in the enclosure wherein the elongated members are in an upright packed condition when the device is inserted into a disc space between two adjacent vertebrae, and wherein the elongated members are in the form of hollow tubes or solid rods, a pliable retainer positioned transversely in the enclosure, wherein the pliable retainer comprises a plurality of spaced-apart holes, and wherein at least one of the plurality of elongated members is positioned in at least one of the plurality of spaced-apart holes, and at least one tab coupled to the enclosure for attaching the pseudo arthrosis device to a vertebrae.
A pseudo arthrosis device, comprising:
- an enclosure formed from a synthetic fabric that is permeable;
- a plurality of elongated members, wherein at least two of the elongated members are packed together longitudinally in the enclosure, wherein the elongated members are in an upright packed condition when the device is inserted into a disc space between two adjacent vertebrae;
- a pliable retainer positioned transversely in the enclosure, wherein the pliable retainer comprises a plurality of spaced-apart holes, and wherein at least one of the plurality of elongated members is positioned in at least one of the plurality of spaced-apart holes;
- and
- wherein at least one of the plurality of elongated members comprises a hollow elongated member.
A method of supporting adjacent vertebrae in a spinal column, comprising:
- inserting a pseudo arthrosis device between the adjacent vertebrae such that a plurality of elongated members formed of a biocompatible polymer in an enclosure of the arthrosis device is positioned longitudinally in a disc space between the adjacent vertebrae, wherein at least two of the elongated members are packed together longitudinally in the enclosure, wherein the elongated members are in an upright packed condition, wherein the elongated members are in the form of hollow tubes or solid rods and wherein the enclosure is formed from a synthetic fabric that is permeable, wherein a pliable retainer is positioned transversely in the enclosure, wherein the pliable retainer comprises a plurality of spaced-apart holes, and wherein one of the plurality of elongated members is positioned in one of the plurality of spaced-apart holes;
- and
- attaching a tab coupled to the enclosure of the pseudo arthrosis device to an adjacent vertebra to secure the pseudo arthrosis device in the disc space.
