Abstract
A method for repairing a defect in the annulus of an intervertebral disc uses a port through a vertebra adjacent the disc for passage of a rivet insertion tool to place a first part of a two-part annulus repair rivet against an internal surface of the annulus adjacent the defect. A separate rivet insertion tool places a second part of the annulus repair rivet on an external surface of the annulus adjacent the defect. The first and second parts are secured together, repairing the defect.
Claims16
A two part annulus repair rivet comprising:
- a first part of the two part annulus repair rivet delivered through a port and adapted to be positioned at an internal surface of the annulus adjacent the defect via a first rivet tool;
- a second part of the two part annulus repair rivet adapted to be positioned on an external surface of the annulus adjacent the defect via a second rivet tool;
- wherein the first part of the annulus repair rivet engages the second part of the annulus repair rivet to close the defect in the annulus,
- wherein each of the two part annulus repair rivet further comprises a distal end and a proximal portion extending from the distal end, each distal end having an area sufficient to completely cover the defect,
- each distal end comprises a curvature complementing a curvature of the annulus to provide a form-fitting mating between each distal end and the annulus,
- wherein the proximal portion of the first part of the annulus repair rivet engages the proximal portion of the second part of the annulus repair rivet,
- wherein the proximal portion of the first part of the annulus repair rivet extends from a convex side of the distal end of the first part of the annulus repair rivet and the proximal portion of the second part of the annulus repair rivet extends from a concave side of the distal end of the second part of the annulus repair rivet, and
- wherein the first rivet tool is configured to engage the first part of the annulus repair rivet from the convex side of the distal end of the first part of the annulus repair rivet and the second rivet tool is configured to engage the second part of the annulus repair rivet from the concave side of the distal end of the second part of the annulus repair rivet.
