Fusion techniques are considered the gold standard for treatment of lumbar spinal instability, although there are many shortcomings and disadvantages. In the past two decades the concept of dynamic stabilization has been introduced in clinical practice. A more thorough knowledge of the spinal biomechanics has led to the ability to modify the loads within the spinal unit. Many different devices based on this concept were designed. Almost all these devices are percutaneous or minimally invasive. Thus, not only surgeons but also interventional radiologists can play a major role in the treatment of the degenerated spine.
融合技术被认为是治疗腰椎不稳的金标准，尽管存在许多缺点和不足。在过去二十年中，动态稳定化的概念已被引入临床实践。对脊柱生物力学更深入的了解使得改变脊柱单元内负荷成为可能。基于这一概念设计了许多不同的装置。几乎所有这些装置都是经皮的或微创的。因此，不仅外科医生，介入放射科医生在退变脊柱的治疗中也能发挥重要作用。
