Research Progress of Prosthetic Disc Nucleus Materials

The postoperative bearing capacity of lumbar vertebrae will be uneven with removal of nucleus pulposus, which is one of the traditional surgical methods for protrusion of lumbar intervertebral disc. However, the development of prosthetic disc nucleus provides a new direction for the therapy of protrusion of lumbar intervertebral disc. This paper discusses the types, characteristics and existing problems of prosthetic disc nucleus materials to expect that prosthetic disc nucleus implantation can improve the health condition of patients with protrusion of lumbar intervertebral disc.
