Abstract
Novel prosthetic nuclear implants for insertion into vertebral discs are prepared by dehydrating hydrated bulky hydrogel discs under specific conditions so as to reduce the water content as low as possible (down to about 10% by weight) but without distortion of the implants, without the formation of concavities and sharp edges, and without changing the shape of the hydrated implant.
