Minimally invasive vertebral augmentation techniques in osteoporotic fractures

Minimally invasive vertebral augmentation techniques fill the gap between conservative treatment and open surgical fusion in the treatment of osteoporotic vertebral fractures. Both vertebroplasty (VP) and kyphoplasty (KP) have proven to be effective in the reinforcement of a fractured vertebral body and provide pain relief, but both procedures have technical differences. Furthermore, patient selection criteria are still under debate, as no randomized comparison trials of VP and KP exist. A competitive environment has arisen between both methods. In the authors' opinion, VP and KP do not replace, but complement each other and offer both potential benefits. It is the purpose of this article to outline the different kinds of application of both methods. © Urban & Vogel.
