A pseudo arthrosis device (20) may be placed in a disc space to provide support for adjacent vertebrae. The device may have an enclosure (22) formed from a flexible, permeable material. A plurality of elongated members (24) may be packed longitudinally in the enclosure (22). The elongated members (24) may be compressible and/or flexible. In certain embodiments, elongated members (24) 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 (24) are disposed longitudinally between the adjacent vertebrae. The pseudo arthrosis device (20) may include a tab (28) designed to couple the enclosure to an adjacent vertebrae. |
