Minimally invasive dynamic stabilization of the degenerated lumbar spine

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.
