1. A method for treating a spinal disc having an outer relatively intact annulus defining a disc space and an inner defective nucleus pulposus within said disc space, comprising the steps of:

  • determining the integrity of said annulus by subjecting the annulus to a first pressure applied internally of said annulus;

    providing access to said nucleus pulposus through said annulus without removing any tissue from said annulus or from said nucleus pulposus; and

    sealably injecting curable biomaterial through said annulus access directly into said nucleus pulposus at a second pressure selected to be correlated with said first pressure, wherein said curable biomaterial is injected at a pressure selected to not cause distraction of said disc space.
