Disclosed herein are methods for treating a defect in a spinal disc nuclear space, comprising: (a) creating an opening by open, percutaneous or laparoscopic techniques to access the defect in the nuclear space; (b) removing a desired amount of tissue from the nuclear space; (c) positioning a delivery catheter through the opening; (d) fluidically isolating the nuclear space by blocking the opening with a blocking component of the catheter; (e) delivering an in-situ curable liquid material through a lumen of the catheter to the nuclear space; and (f) maintaining the isolating until the liquid material has cured. Also disclosed are treatment systems and materials for prostheses.
