Spinal disc replacement. Magnetic resonance imaging (MRI) scan of a section through the lumbar spine of a 46-year-old patient with a total disc replacement, showing the prosthetic intervertebral disc (black, centre) in place between the L4-L5 vertebrae. Disc replacement is a form of arthroplasty (joint replacement) where a degenerated intervertebral disc in the spine is replaced with a prosthetic one.
