Study Design Retrospective study. Objective To compare clinical outcomes, radiographic evaluations including bony union rate and incidence of osteoporotic vertebral fractures (OVFxs), and perioperative complications following posterior lumbar interbody fusion (PLIF) between patients ≥80 years of age and those <80 years. Methods Ninety-six patients ≥70 years old who underwent PLIF were reviewed....

Study design: An in vitro biomechanical flexibility and fatigue test comparing two different lumbar interbody fusion cages using mono segmental lumbar spine specimens. Objective: To investigate and compare the stabilizing effect of a transforaminal lumbar interbody fusion (TLIF) cage against an expandable posterior lumbar interbody fusion (PLIF) cage. Method: Six intact human lumbar spine segme...

PURPOSE The aim of this study is to compare the clinical and radiological outcome of minimally invasive posterior lumbar interbody fusion (MI-PLIF) in revision and primary cases. METHODS In a retrospective study, we compared the clinical and radiological results of MI-PLIF for lytic spondylolisthesis (n = 28) and recurrent radiculopathy after herniated disc surgery (n = 28). Clinical outcome ...

OBJECTIVE The purpose of this study was to evaluate the clinical and radiological results of instrumented posterior lumbar interbody fusion (PLIF) using an unilateral cage. METHODS Seventeen patients with unilateral radiculopathy who underwent bilateral percutaneous screw fixation with a single fusion cage inserted on the symptomatic side for treatment of focal degenerative lumbar spine disea...

Detailed studies of flame-vortex interactions are extremely valuable to improve our understanding of turbulent combustion regimes. Combined experimental and numerical studies have already been performed in the premixed case during previous investigations. Therefore, we decided to carry out a detailed experimental investigation on the regimes observed during interaction of a vortex ring and a no...

This study aims to assess the differences in the radiological and clinical results depending on the lordotic angles of the cage in posterior lumbar interbody fusion (PLIF). We reviewed 185 segments which underwent PLIF using two different lordotic angles of 4° and 8° of a polyetheretherketone (PEEK) cage. The segmental lordosis and total lumbar lordosis of the 4° and 8° cage groups were compare...

The authors describe a hybrid technique that involves a combination of open decompression and posterior lumbar interbody fusion (PLIF) and percutaneously inserted pedicle screws. This technique allows performance of PLIF and decompression via a midline incision and approach without compromising operative time and visualization. Furthermore, compared to standard open decompression, this approach...

This study sought to determine the outcomes of posterior lumbar interbody fusion (PLIF), via a unilateral approach, in selected patients who presented with unilateral leg pain and segmental instability of the lumbar spine. Patients with a single level of a herniated disc disease in the lumbar spine, unilateral leg pain, chronic disabling lower back pain (LBP), and a failed conservative treatmen...

Objective. The authors present the clinical results obtained in patients who underwent interspinous fusion device (IFD) implantation following posterior lumbar interbody fusion (PLIF). The purpose of this study is investigating the feasibility of IFD with PLIF in the treatment of lumbar spondylolisthesis. Methods. Between September 2013 and November 2014, 39 patients underwent PLIF and subseque...

STUDY DESIGN Prospective longitudinal study. PURPOSE To determine if preoperative psychological status affects outcome in spinal surgery. OVERVIEW OF LITERATURE Low back pain is known to have a psychosomatic component. Increased bodily awareness (somatization) and depressive symptoms are two factors that may affect outcome. It is possible to measure these components using questionnaires. ...
