Does TLIF aggravate adjacent segmental degeneration more adversely than ALIF? A finite element study.
AIM To determine whether transforaminal lumbar interbody fusion aggravate adjacent segmental degeneration more adversely than anterior lumbar interbody fusion. MATERIAL AND METHODS A normal finite element model, an anterior lumbar interbody fusion model and a transforaminal lumbar interbody fusion model of L3-5 were developed. 800 N compressive loading plus 10 Nm moments simulating flexion, e...
متن کاملDoes disc space height of fused segment affect adjacent degeneration in ALIF? A finite element study.
AIM The restoration of disc space height of fused segment is essential in anterior lumbar interbody fusion, while the disc space height in many cases decreased postoperatively, which may adversely aggravate the adjacent segmental degeneration. However, no literature available focused on the issue. MATERIAL AND METHODS A normal healthy finite element model of L3-5 and four anterior lumbar inte...
متن کاملLong-Term Effects of Segmental Lumbar Spinal Fusion on Adjacent Healthy Discs: A Finite Element Study
STUDY DESIGN Experimental study. PURPOSE The aim of the study was to develop a finite element (FE) model to study the long-term effects of various types of lumbar spinal interventions on the discs adjacent to the fused segment. OVERVIEW OF LITERATURE Earlier FE studies have been limited to one particular type of fusion and comparative quantification of the adjacent disc stresses for differe...
متن کاملComparison of posterior versus transforaminal lumbar interbody fusion using finite element analysis. Influence on adjacent segmental degeneration.
OBJECTIVES To compare the influence of posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) on adjacent segment degeneration (ASD). METHODS The study was carried out in the Traumatology and Orthopedics Laboratory, Department of Traditional Chinese Medicine, Medical School, Jinan University, Guangzhou, China, between December 2013 and November 2014. A norm...
متن کاملAdjacent segmental degeneration following Wallis interspinous stabilization implantation
Adjacent segmental degeneration (ASD) is a major issue after pedicular fixation. This study examined the degeneration of the adjacent levels due to the insertion of the Wallis interspinous stabilization system compared with discectomy, using magnetic resonance imaging (MRI).Thirty-eight patients diagnosed with lumbar degeneration disorders at L4-L5 were reviewed: 19 patients underwent discectom...
