1. A method of reinforcing an annulus of an intervertebral disc comprising:

  • identifying a pre-existing defect in the annulus;

    wherein the defect is bordered by an outermost layer of the annulus and an innermost layer of the annulus, the method comprising;

    providing a biocompatible support member; and

    implanting the biocompatible support member along an innermost surface of the annulus without removing a substantial portion of the nucleus pulposus;

    positioning said biocompatible support member entirely beyond said defect;

    positioning said biocompatible support member to span said defect, thereby closing said defect and minimizing leakage of a naturally-occurring nucleus pulposus material into the defect;

    anchoring the biocompatible support member;

    wherein said biocompatible support member extends entirely along the innermost layer of the annulus, andwherein said biocompatible support member is positioned in front of said defect and disposed against said innermost layer, thereby reinforcing the annulus.
