Lumbar disc replacement is a developing primary surgical treatment for patients with
degenerative disc disease. The goals of disc arthroplasty are to remove the native
nucleus pulposus and to preserve motion at that disc level. Devices being developed
include artificial replacement of the nucleus pulposus and artificial replacement
of the entire disc. With the recent approval by the Food and Drug Administration of
the Charite artificial disc, this procedure will be used with increasing frequency.
This article reviews pertinent anatomy and pathology of the functional spinal unit
as well as the types of devices being developed and the factors related to development
of a successful implant. Clinical outcomes and complications are also discussed.
