Abstract
Total Cervical Disc Replacement is a modern option after cervical discectomy. Preservation of motion should hopefully decrease the rate of adjacent segment disease, a well known and discussed problem after rigid fusion of the spine. The review of the literature and the actual state of controversy will not be part of this short report. MRI is the method of choice to investigate the spinal canal with its content. With the recent introduction of upright, multi-position MRI it is now possible to perform weight-bearing imaging in different positions and to detect dynamic compressions[1–6]. There are many artificial discs on the market, which cost about 4 times more than a standard cervical intervertebral fusion cage. For many surgeons the spinal cord and the epidural space behind an implanted level and at the adjacent levels should be reliably assessable with MR imaging postoperatively.
