摘要：
A method for treating a diseased or damaged spinal disc comprises the steps of: (a) providing access to the nucleus pulposus through the annulus (b) removing at least a portion of the nucleus pulposus to create an intradiscal space (c) determining the size of the intradiscal space and (d) sealably introducing under pressure a curable biomaterial through the annulus directly into the intradiscal space. The step of determining the size of the intradiscal space may be accomplished by expanding a compliant balloon within the intradiscal space using a contrast medium capable of visualization under fluoroscopy. The curable material is sealably introduced through a vented needle inserted through the opening. The curable biomaterial is introduced until a quantity of the material flows into the vent.
