Classification of posterior dynamic stabilization devices

A Short History of Posterior Dynamic Stabilization

Interspinous spacers were developed to treat local deformities such as degenerative spondylolisthesis. To treat patients with chronic instability, posterior pedicle fixation and rod-based dynamic stabilization systems were developed as alternatives to fusion surgeries. Dynamic stabilization is the future of spinal surgery, and in the near future, we will be able to see the development of new de...

Biomechanics of Posterior Dynamic Stabilization Systems

Spinal rigid instrumentations have been used to fuse and stabilize spinal segments as a surgical treatment for various spinal disorders to date. This technology provides immediate stability after surgery until the natural fusion mass develops. At present, rigid fixation is the current gold standard in surgical treatment of chronic back pain spinal disorders. However, such systems have several d...

An In Vitro Comparison of Three Posterior Dynamic Motion-Sparing Lumbar Stabilization Devices

Introduction Preclinical data is required to select among various posterior dynamic stabilization devices on the market today. Unfortunately, very little is available. The purpose of this biomechanical study was to compare the kinematics, foraminal areas, and disc heights in cadaveric lumbar spines treated with three types of posterior dynamic stabilization devices: PercuDyn (Interventional Spi...

Low back pain is described as a deep pain surrounding the waist in a “belt style,” frequently seen in the midline, but which may spread to the hips and upper thighs. In recent years, degenerative disc disease has been observed as the most important result of low back pain. Tearing of the disc capsule, including nerve root irritation from the chemical substances that are expelled (chemical nocic...
