Study type | Interventional |
Until now, arthrodesis (intervertebral fusion) is the formal treatment for the lumbar and
cervical degenerative disc disease : arthrodesis has been the standard surgical treatment
for the patients when nonsurgical management has failed. However , it has shown out some
drawbacks : pseudoarthrosis may appear in the short term, and junctional degeneration in the
long term.
The replacement of the intervertebral disc by a prosthesis (arthroplasty) has been since a
few years a major alternative therapeutic to the arthrodesis.: it demonstrates great
functional results and less post-interventional complications. It is indicated to restore a
normal function of the spine (motion is kept)and to avoid deterioration of the adjacent
spinal segments over the long time.
In this clinical study, we will distinguish the cervical discal pathology and the lumbar
discal pathology.
The purpose of this study is to analyze the results of the arthroplasty in terms of
functional effects, quality of life, anatomical results and economical results.
