STUDY DESIGN Retrospective study. PURPOSE To analyze outcomes of posterior lumbar interbody fusion (PLIF) stand-alone cages. OVERVIEW OF LITERATURE PLIF for degenerative disk disease using stand-alone cages has lost its popularity owing to implant-related complications and pseudoarthrosis. METHODS We analyzed the records of 45 patients (18 women, 27 men), operated between January 1994 and...

BACKGROUND The purpose of this study was to evaluate lumbar spine-related functional disability in individuals 10 years after lumbar decompression and lumbar decompression with posterior lumbar interbody fusion (PLIF) with corundum implants surgery for degenerative stenosis and to compare the long-term outcome of these 2 surgical techniques. MATERIAL/METHODS From 1998 to 2002, 100 patients wi...

Study Design:Retrospective study. Objective:To report the clinical and radiological results of posterior lumbar interbody fusion(PLIF)using titanium intervertebral spacers in elderly patients over 70 years. Summary of Background Data:PLIF with intervertebral spacers has been introduced to treat degenerative lumbar disorders. However,in the elderly patients,it is concerned that there are several...

A technique that combines two-photon excitation (TPE), planar laser induced fluorescence (PLIF) and optical connectivity (OC) has been applied to capture the instantaneous geometry of a cross-section normal main direction core liquid jet exposed crossflow air during atomisation. This paper demonstrates nanosecond pulse can excite in an atomising Rhodamine B-dyed water jet. It shows TPE-PLIF on ...

Abstract The catalytic and gas-phase combustion of fuel-lean H2/CO/O2/N2 mixtures over palladium was investigated experimentally numerically at a global equivalence ratio φ = 0.285, H2:CO volumetric ratios 1-4, pressures 1-8 bar catalyst surface temperatures 950-1200 K. In situ planar laser induced fluorescence (PLIF) the OH radical monitored homogeneous inside channel-flow reactor, while 1-D R...

This work aimed to test and optimise reactive Planar Laser-Induced Fluorescence (PLIF) methods for the visualisation of micromixing regions in chemical reactors using standard PLIF Particle Image Velocimetry (PIV) equipment with laser source 512 nm. Two were tested: (i) an acid–base reaction fluorescein as reaction-sensitive tracer (ii) Fenton’s reaction, Rhodamine B tracer. Both test-reactions...

BACKGROUND The aim of study was to evaluate the effect of mechanical ventilation mode type, pressure-controlled ventilation (PCV), or volume-controlled ventilation (VCV) on intra- and postoperative surgical bleeding in patients undergoing posterior lumbar interbody fusion (PLIF) surgery. METHODS This was a prospective, randomized, single-blinded, and parallel study that included 56 patients u...

OBJECTIVE This study aimed to investigate radiographic fusion rates at L4-5 and L5-S1 after single level posterior lumbar interbody fusion (PLIF) and evaluate the relationship between fusion rates and preoperative disc slope angle (DSA), lumbar lordosis (LL), segmental angle (SA), and pelvic parameters. METHODS We conducted a retrospective review of patients who underwent single level PLIF at...

BACKGROUND Surgical interventions such as posterior lumbar interbody fusion (PLIF) with and without posterior instrumentation are often employed in patients with degenerative spinal conditions that fail to respond to conservative medical management. The VariLift® Interbody Fusion System was developed as a stand-alone solution to provide the benefits of an intervertebral fusion device without th...
