Introduction[edit | edit source]

Artificial disc replacement is an modern procedure that is gaining popularity in spine surgery.[1] The first lumbar artificial disc replacement was in in the late 1950s. Most of the current available artificial disc replacement devices attempt to copy the biomechanics of an intact spinal motion segment, however replacement techniques for the the nucleus disc replacement are only being now developed.[2]

Sub Heading 2[edit | edit source]

Lumbar disk replacement involves replacing a worn or degenerated disk in the lower part of your spine with an artificial disk made of metal or a combination of metal and plastic.

The usual reason for lumbar disc arthroplasty is lumbar spinal pain that is present due to degenerative disc disease and conservative therapy has proved to be unsuccessful. Lumbar disc arthroplasty is less frequently used than lumbar fusion as it has more contraindications eg osteoporosis or osteopaenia, spinal stenosis or spinal deformities such as scoliosis.[3]
