Abstract
A two part annulus repair rivet for repairing a defect in the annulus of an intervertebral disc includes a first part delivered through a port and adapted to be positioned at an internal surface of an annulus adjacent a defect and a second part adapted to be positioned on an external surface of the annulus adjacent the defect. The first and second parts are secured together, repairing the defect.

A method for annulus repair, the method comprising:
- drilling a shaft at an exterior surface of the vertebral body opposite a defect through which a portion of the nucleus emerges for purposes of establishing a port;
- inserting an internal tool through the shaft and into the nucleus;
- gripping the emerging portion with the inserted internal tool;
- pulling the gripped portion back into the nucleus;
- removing the inserted internal tool from the shaft;
- repairing the defect through the shaft after the emerging portion has been pulled back into the nucleus.

A method for annulus repair, the method comprising:
- establishing a port through a vertebral body and into a nucleus of an intervertebral disc having an annulus and an emerging portion emerging outside of the nucleus through a defect;
- inserting an internal tool through the port and into the nucleus;
- gripping a portion of the nucleus with the inserted internal tool;
- pulling the gripped portion to bring the emerging portion back into the nucleus;
- repairing the defect after the emerging portion has been brought back into the nucleus;
- and
- inserting through the port a two part annulus repair rivet to block the defect by:
- using an internal rivet tool to pass a first part of the two part annulus repair rivet through the port and to position the first part of the annulus repair rivet at an internal surface of the annulus adjacent the defect;
- using an external rivet tool separate from the internal rivet tool to position a second part of the two part annulus repair rivet at an external surface of the annulus adjacent the defect;
- and
- securing the first part of the annulus repair rivet to the second part of the annulus repair rivet to close the defect in the annulus.
