[Degeneration and osteoporosis of the spine. Is there a modified procedure?].

Reduced bone quality due to osteoporosis poses a fundamental problem in spine surgery instrumentation. The consequences observed most often are insufficient implant anchoring and adjacent fractures. In cases of manifest osteoporosis, several modern anchoring possibilities are at our disposal that, to differing degrees, increase the stability of the instrumentation. Cement augmentation of a fractured vertebra by means of kyphoplasty or vertebroplasty verifiably leads to significantly better pain reduction than conservative treatment does, at least in the short-term postoperative course. A difference between these two techniques has not yet been substantiated. The rate of adjacent fractures occurring after cement augmentation is not higher than in conservatively treated patients.
