During Surgery, The Lumbar Disc Replacement Device Is Implanted In The Spine As A Prosthetic Device
Lumbar Disc Replacement Device

Ulf Fernstrom, a Swedish surgeon, inserted the first lumbar disc prosthetic in the late 1950s. He inserted a steel ball-shaped artificial disc using an anterior technique. The deteriorated nucleus, which was thought to produce chemical components that caused pain, was excised during the treatment. The steel ball was implanted with the goal of maintaining motion and height in the disc space. Although early results were encouraging, long-term device failure was attributed to an excessive concentration of compressive loads with subsidence into the subchondral bone.

Lumbar Disc Replacement Device designs emerged using concepts from total knee and hip prostheses. The SB Charité was the first prosthesis created by Schellnack and Buttner-Janz in the early 1980s to be commercially supplied as a TDR. The implant was made up of two metallic end plates and an ultra-high molecular weight polyethylene (UHMWPE) sliding core. The first system (SB Charité I) was made up of tiny end plates that resembled shells. The vertebral body in numerous instances subsided over time as a result of stress concentrations along this tiny surface area. Later, subsequent iterations of the SB Charité were utilised in its place.
