BACKGROUND: Traditionally, spinal degeneration and injury have been associated with
abnormal intervertebral motion; thus, treatment for lowback pain has centered on prevention …

Study Design. Nondestructive flexibility tests were performed in vitro, comparing multiple
conditions of fixation in a single group of specimens. Objective. To compare the …

The conventional surgical treatment for chronic low back pain caused by degenerative
disorders in the lumbar spine is spinal fusion. This may be compared with arthrodesis of the …

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 …

Background Despite numerous biomechanical studies have been carried out on dynamic
stabilizers, there is very little information on their hybrid application, especially when …

Degenerative lumbar spinal stenosis (DLSS) is a disabling disease common in the elderly, a
population that has been estimated to double by 20251. In 1954, Verbiest2 first described …

Dynamic stabilization may provide a more physiologic alternative to fusion for patients
suffering from low back pain. A validated 3-D nonlinear finite element model of the intact L3 …

Study Design. A literature review. Objective. To evaluate the mechanisms of action and
effectiveness of posterior dynamic stabilization devices in the management of painful spinal …

Rationale behind motion preservation devices is to eliminate the accelerated adjacent-level
effects (ALE) associated with spinal fusion. We evaluated multidirectional flexibilities and …

Arthrodesis of the spine is an important and useful technique for the management of spinal
disorders including deformity, trauma, segmental instability, and symptomatic disc …
