Almost 150 artificial disk replacements per year
At times an artificial disk replacement may seem indicated to help the patient to get well again.
Dr. Helmbrecht with about 150 annual implantations ranges among the most experienced spine surgeons.
Thanks to progress in implant development modern artificial disk replacements are fitted ideally to the functional setting of the cervical spine and allow for natural movement – preserving by this means the mobility of the neck. Additionally their elasticity lets them work as shock absorbers just like their natural counterparts. This helps to prevent the adjacent sections of the spine from undue stresses.
Insertion of an artificial disk replacement is done through a small incision at the neck. After removal of the prolapsed disk the artificial disk replacement is adjusted between the vertebrae. It is fixed with two titanium plates allowing for optimal adhesion of the implant to the bone so that a loosening is mitigated. Between the two titanium plates there is a polymeric nucleus (polyethylene) and another polymer (polyurethane) is used to encase the prosthesis and to seal it off the surrounding tissues.
The intervention is done under general anesthesia and takes about one hour. Already two hours after the surgery you can walk by yourself and two days later you may go back home again.
Only in rare cases a prosthesis cannot be used. This is the case in osteoporosis, tumors, myelopathy (changes of the spinal cord) or if degeneration of the disk and the facet joints is too severe. In such cases a fusion is done after thorough decompression. For this purpose we use a cage made of PEEK (a synthetic material that is highly biocompatible).

For about six weeks you will have to carry a neck brace and then it is recommended to start an individually targeted and professionally supervised physiotherapy.
When may I resume my sports activities?
After about six weeks you should be able to go swimming or to ride your bicycle. Your may gradually resume your usual sports activities after 9 to 12 weeks.
When can I go back to work?
After two weeks you can resume simple office work and slight physical work. You shouldn’t do any hard physical work during the first 8 weeks and then only gradually increase.
What is the success rate?
In the international scientific literature success rates of more than 90% are quoted.

|After the intervention||
- Up-to-date artificial disks provide for a natural mobility and ideal functionality of the damaged cervical spine
- Short hospital stay: in general you may go back home three days after the intervention
- A adjacent segment degenration can mostly be prevented
- Return to moving and walking directly after surgery is possible
- Already two weeks after the surgery you may largely resume your usual activities
- A high success rate
