A device for implantation between interspinous processes made of bioresorbable materials is described. The implant has a spacer that can be placed between adjacent spinous processes to limit the movement of the vertebrae. Once inserted between interspinous processes, the implant acts to limit extension (backward bending) of the spine without inhibiting the flexion (forward bending) of the spinal column. The device is used as an adjunct to repair or regeneration of an intervertebral disk.
