[Intervertebral disk endoprosthesis--development and current status].

The clinical use of SB endoprosthesis and new international models and research results have increased the importance of functional intervertebral disc prosthetics as an alternative method to certain fusion operations. An analysis of the development of intervertebral disc prostheses and special problems regarding this development will be discussed.

Biomechanics of the SB Charité lumbar intervertebral disc endoprosthesis.

The SB Charité intervertebral disc prostheses consist of two metal end-plates and an interposed polyethylene slide core. These were subjected to static and dynamic testing in a servohydraulic test rig. When embedded in polypropylene, the prostheses were found to function adequately under a high static load, and under a lighter dynamic load for a long time. When tested in a cadaveric vertebral segment, a large end-plate surface area proved to be of critical importance in preventing collapse of the prosthesis into the vertebral body.
