background: recurrent lumbar disk herniation (rldh) is one of the major causes of failure of standard discectomy. the optimal treatment method for rldh is controversial. in the current study, we aimed to compare the clinical and functional outcomes of treating rldh with discectomy alone and discectomy associated with posterolateral interbody fusion (plif). material and methods: there were 41 pa...

STUDY DESIGN Eighty-four patients who had been treated for degenerative spinal diseases between January 2006 and June 2009 were reviewed retrospectively. PURPOSE We aimed to compare the clinical and radiologic findings of manual workers who underwent posterolateral fusion (PLF) or posterior interbody fusion (PLIF) involving fusion of 3 or more levels of the spine. OVERVIEW OF LITERATURE Pre...

A method for the simultaneous measurement of velocity and passive scalar concentration fields by means of particle image velocimetry (PIV) and planar laser induced florescence (PLIF) techniques is described here. An application of the combined PIV-PLIF system is demonstrated by performing simultaneous velocity and concentration measurements in the near field of a turbulent jet mixing flow. The ...

Study Design Retrospective cohort study among Medicare beneficiaries who underwent posterior lumbar interbody fusion (PLIF) surgery. Objective To identify the complication rates associated with the use of bone morphogenetic protein 2 (BMP2) in PLIF. Human BMP2 is commonly used in the "off-label" manner for various types of spine fusion procedures, including PLIF. However, recent studies have ...

Planar laser-induced fluorescence (PLIF) images of nitric oxide (NO) in hypersonic flow over a wedge and a hemisphere are compared with a theoretical PLIF model. The theoretical PLIF images are based on computational fluid dynamics (CFD) models including a perfect-gas model and a nonequilibrium chemistry model. Two dimensional maps of the flow parameters generated by the CFD are used to predict...

BACKGROUND Both unilateral pedicle screw fixation with posterior lumbar interbody fusion (PLIF) and bilateral pedicle screw fixation with PLIF are used to treat lumbar degenerative diseases (LDD). However, which one is a better treatment for LDD remains considerable controversy. Therefore, the focus of this meta-analysis was to assess the merits and shortcomings of efficacy of these 2 surgical ...

STUDY DESIGN Prospective randomized controlled trial. OBJECTIVE The aim of this study was to monitor the quality control of robot-assisted pedicle screw fixation accuracy by using a cumulative summation (CUSUM) test at the initial stage of its application. SUMMARY OF BACKGROUND DATA Although robot-assisted pedicle screw fixation reduces screw misplacement rates and provides critical support...

OBJECT Previous studies of surgical complications associated with posterior lumbar interbody fusion (PLIF) are of limited value due to intrastudy variation in instrumentation and fusion techniques. The purpose of the present study was to examine rates of intraoperative and postoperative complications of PLIF using a large number of cases with uniform instrumentation and a uniform fusion techniq...

PURPOSE To compare 2 methods of fusion in the treatment of lumbar spondylolisthesis: posterior lumbar interbody fusion (PLIF) and intertransverse fusion (ITF). METHODS 20 patients with lumbar spondylolisthesis were randomly allocated to one of 2 groups: decompression, posterior instrumentation, and PLIF (n=10) or decompression, posterior instrumentation, and ITF (n=10). The Oswestry low back ...

STUDY DESIGN Retrospective. PURPOSE To compare the clinical and radiological outcomes of posterolateral lumbar interbody fusion (PLIF) and posterolateral lumbar fusion (PLF) in monosegmental vacuum phenomenon within an intervertebral disc. OVERVIEW OF LITERATURE The vacuum phenomenon within an intervertebral disc is a serious form of degenerative disease that destabilizes the intervertebral...
