BandscheibenprotheseWhy does a disc prosthesis is an alternative therapy?
In extensive changes in the spine with the disc is used up as a treatment of choice in frequent cases, the stiffening of the spine with fusion of the vertebral bodies after removal of the disc used. This method has proven itself and, according to according to strict indication a significant improvement in their complaints in some views.
Unfortunately, the overall success of this complex operation is affected by Fehlergebnisse. These include nonunion, and the congestion in the adjacent vertebral segments, which have a greater wear can (so-called connection instabilities). Back pain is the result. This impacts on adjacent joints have long been known, because they almost always after the stiffening of large joints (eg knee or hip) occurred. In these cases showed the use of total joint replacement surgery (total joint) a substantial progress in therapy.
How does a disc prosthesis?
In general, disc prostheses are divided in their structure and localization. In principle, such a band must prosthesis according to the anatomical structure of a normal disc are divided. For example, there nucleus prostheses that replace only the disc nucleus and Bandscheibenvollprothesen simulating both the inner, soft core of the disc and surrounded the outside of a hard elastic material, which is to replace the disc annulus in its function. In addition to disc prosthesis implantation location of its needs. Therefore show cervical, cervical spine, designed for a different structure than lumbar prostheses for the lumbar spine is thought prostheses.
The implantation is carried out depending on the location of minimally-invasive or a major surgical access. The affected disc is removed, the adjacent vertebral bodies freshened to an ingrowth of bone into the bioactive surface of the base and top plate to allow the disc prosthesis. In between, a high molecular weight polyethylene inlay is implanted, which mimics the function of the natural disc. The fixation of the disc prosthesis is stable and cementless anchorage of teeth and a bioactive coating with a slightly textured surface, which facilitates rapid ingrowth of the prosthesis surface into the adjacent bone.
Are there after disc prosthesis surgery significant limitations?
Usually not. In most cases, the day of the operation once again an independent steps possible. After a few days, then usually after appropriate healing of the wound, the patients are discharged home. About 6 weeks, a special soft corset be worn. After a load capacity of the professional and sporting life, as a rule is established.
Advantages of the disc prosthesis to a stiffening:
- Maintaining the flexibility
- No connection instability of Nachbarsegemente
- Rapid Rehabilitation
