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...

BACKGROUND With a steep increase in the number of instrumented spinal fusion procedures, there is a need for comparative data to develop evidence based treatment recommendations. Currently, the available data on cost and clinical effectiveness of the two most frequently performed surgeries for lumbar spondylolisthesis, transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody...
