Objective To analyze the biomechanical changes of lumbar adjacent segment by comparing
the biomechanics after the surgery of transforaminal lumbar interbody fusion (TLIF) and …

While lumbar spinal fusion using rigid rods is a prevalent surgical technique, it can lead to
complications such as adjacent segment disease (ASDis). Dynamic stabilization devices …

Background and purpose Internal fixation surgeries are currently the most effective
treatments for lumbar spondylolysis, but the optimal fixation method is still on debate. This …

Abstract Background The Dynesys system provides stability for destabilized spines while
preserving segmental motion. However, clinical studies have demonstrated that the Dynesys …

Background Instrumented lumbar arthrodesis has been established as the gold standard in
the care of patients with degenerative disc disease. However, spinal fusion results in the …

The spine naturally has a nonlinear force-deflection characteristic which facilitates passive
stability, and thus there is a need for spinal implants that duplicate this behavior to provide …

Objective Oblique lateral interbody fusion (OLIF) surgery is a minimally invasive spinal
surgery technique that has become increasingly popular in recent years. The primary …

Study Design. The effect of long, rigid fixation on adjacent level hypermobility was
investigated in a human cadaver model with and without a transitional posterior dynamic …

Study Design Descriptive. Objectives Trabecular bone in the vertebrae is critical for the
distribution of load and stress throughout the neuroaxis, as well as the intervertebral disk …

Rigid instrumentations have been widely used for spinal fusion but they come with
complications, such as adjacent disc degeneration. Dynamic instrumentations have been …
