The artificial spinal disc
The artificial disc is an alternative to acampsia. Regardless, it is nowadays still considered the gold standard in surgical treatment of chronic degenerative disc disease. The surgery causes a reduction in pain with the removal of the diseased disc and tranquilisation of the segment. A major problem here is the accelerated degeneration (wear) of the adjacent segments, however. The artificial disc replacement has been developed, to restore the physiological (healthy) mobility of the degenerated spinal segment and to reduce the negative effects of acampsia. The first functional three-piece disc prosthesis has been implanted in the human lumbar spine in 1984. After the lumbar disc replacement had achieved great successes, the developments in the cervical area headed in the same direction. Almost all of the prosthetic designs for the cervical spine represent miniature models of the lumbar prostheses. The artificial neck disc must also compete with the so far existing gold standard of fusion (acampsia) of the motion segment. The disadvantage of this method is - similar to the lumbar spine - the increased likelihood of accelerated wear of the adjacent intervertebral discs. Studies have shown an increase of pressure in the disc above a stiffened segment by 70% and below 40%. Five years after an acampsia, in 92% of all patients, radiological signs of wear and tear of the adjacent segments were found.
Unfortunately the exertion of an artificial disc is not always possible. Read the following pages to know which patients are suitable for an artificial disc and which are not.
