Spinal graft
Provided herein is a spinal graft that fuses to and stabilizes the spine upon placement thereby helping to prevent spinal stenosis recurrence and eliminating pain associated with an unstable spine. The graft may be coated with a human birth tissue composition. Also provided herein are methods of stabilizing the spine after decompression surgery.
1. A graft comprising:
a superior arm having a surface defining a notch positioned at a central region of the superior arm to receive and contact against an inferior edge of a spinous process of a superior vertebra;
an inferior arm having a surface defining a notch positioned at a central region of the inferior arm to receive and contact against a superior edge of a spinous process of an inferior vertebra;
a first wing for extending into a first vertebral gutter;
a second wing for extending into a second vertebral gutter; and
an effective amount of a flowable human birth tissue material composition deposited on an outer surface of the graft, the flowable human birth tissue material composition comprising one or more morselized placental tissue components.
2. The graft of claim 1 , further comprising at least one area defining an opening for receiving at least one screw for securing the graft.
3. The graft of claim 2 , wherein at least one opening is located in each of the first and second wings such that a screw is configured to be secured within the first and second vertebral gutters.
4. The graft of claim 1 , wherein the graft is prepared from cancellous bone, demineralized cancellous bone, fresh allograft, frozen allograft, freeze dried bone allograft, demineralized freeze dried bone allograft, cortical cancellous bone, or a combination thereof.
5. The graft of claim 1 , wherein the one or more of the placental tissue components is selected from the group consisting of the placental globe, the umbilical cord, the umbilical cord blood, the chorionic membrane, the amniotic membrane, the Wharton's jelly, the amniotic fluid, and other placental gelatins, cells, and extracellular material.
6. A method of stabilizing a vertebral region of a spine following a decompression surgery comprising:
performing a decompression surgery; providing the graft of claim 1 ; engaging the notch of the superior arm with an inferior edge of a spinous process of a superior vertebra; and engaging the notch of the inferior arm with a superior edge of a spinous process of an inferior vertebra, wherein the vertebral region of the spine is stabilized.
7. The method of claim 6 , further comprising the step of securing the graft to the vertebral region with at least one screw, rod, plate, or a combination thereof.
8. A kit for stabilizing the spine following a decompression surgery comprising
a graft as provided in claim 1 ;
and instructions for use thereof.
