Artificial Disk Replacement. Total disk replacement is an investigative procedure for some patients with severely damaged disks. The technique implants artificial disks (ProDisk, Link, SB Charite) consisting of two metal plates and a soft core. The surgery can be performed using a minimally invasive laparoscopic procedure, which is performed through tiny cuts using miniature tools and viewing devices. A study in 2003 was the first to suggest that it may eventually achieve results that are comparable to standard surgeries for disk herniation.
An artificial cushioning device called the prosthetic disk nucleus (PDN) replaces only the inner gel-like core (nucleus pulposus) within the intervertebral space, rather than the entire disk. It is showing promise in early studies.
