Finite element analysis of 3 posterior fixation techniques in the lumbar spine.

Stress Analysis of the Human Ligamentous Lumber Spine-From Computer-Assisted Tomography to Finite Element Analysis

Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...

Effect Of Varying Geometrical And Material Properties And Fixation Techniques In Posterior Lumbar Spinal Instrumentation On Spine Biomechanics: A Finite Element Study

Estimation of spinal loads using a detailed finite element model of the L4-L5 lumbar segment derived by medical imaging kinematics; a feasibility study

Introduction: Low back pain is the most prevalent orthopedic disorder and the first main cause of poor working functionality in developed as wells as many developing countries. In Absence of noninvasive in vivo measurement approaches, biomechanical models are used to estimate mechanical loads on human joints during physical activities. To estimate joint loads via musculoskelet...

Comparison of the Rigid Rod System with Modular Plate with the Finite Element Analysis in Short-Segment Posterior Stabilization in the Lower Lumbar Region.

AIM Many studies are available in the literature on posterior spinal instrumentation, though the use of a rod and a plate is still controversial in the literature. In this study, a finite element analysis of the strength and superiority of modular rigid plate and rod systems, which are used in the lower lumbar region, in comparison with each other was used. MATERIAL AND METHODS A Ti6Al4V (Gra...

Role of Minimally Invasive Spine Surgery in Adults with Degenerative Lumbar Scoliosis: A Narrative Review

Background and Aim: Degenerative lumbar scoliosis is a spinal deformity resulting from advanced disc degeneration and facet arthropathy. Given the inconclusive available literature and lack of high-quality data supporting the role of minimally invasive surgical management of degenerative lumbar scoliosis, this review intends to highlight and compare the various viable minimally invasive surgica...
