The present invention provides a disc restoration system for relieving symptoms of a degenerative disc, comprising: a) a percutaneously insertable expandable element (88) adapted to be (i) inserted in between two adjacent vertebraes of the spinal cord and, (ii) expanded to form a scaffold said scaffold provides mechanical support to said two adjacent vertebraes so as to restore said degenerative disc to approximately the dimensions of a normal disc b) an injectable filler having a first flowable state, and a second non-flowable set state the filler is configured for being introduced, in said first flowable state, into a confined volume formed by the expandable element and the tissues, following the full expansion of said expandable element in said disc and, following introduction of said filler, said filler is adapted to set into said second non-flowable state such that following setting of said filler into said second state said disc is internally supported by said set filler.
