STUDY DESIGN This is a retrospective study. PURPOSE To evaluate the advantages and effects of posterior lumbar interbody fusion (PLIF) using allograft and posterior instrumentation in the lumbar pyogenic discitis, which are resistant to antibiotics. OVERVIEW OF LITERATURE To present preliminary results of PLIF using a compressive bone graft with allograft and pedicle screw fixation in the l...

BACKGROUND Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spin...

OBJECTIVE Posterior accessed lumbar interbody fusion (PALIF) has a clear objective to restore disc height and spinal alignment but surgeons may occasionally face the converse situation and lose lumbar lordosis. We analyzed retrospective data for factors contributing to a postoperative flat back. METHODS A total of 105 patients who underwent PALIF for spondylolisthesis and stenosis were enroll...

Reactant mixing and combustion are investigated in an optically accessible, self-excited linear detonation combustor. The field is captured using 100 kHz planar laser-induced fluorescence (PLIF) imaging of acetone as a tracer the fuel supply, while chemiluminescence excited-state hydroxyl (OH*) radicals simultaneously resolves evolution wave. Time sequences acquired over multiple cycles each te...

The present review describes the current achievements in applications of a planar laser-induced fluorescence (PLIF) method for diagnostics liquid films, bubbles, individual droplets, and sprays. Such flows are related with strongly curved interphases, which often results additional high errors during PLIF data quantification because laser light reflection, refraction, absorption. demonstrates t...

OBJECTIVE For multi-level spondylolysis patients, surgeons commonly choose to fix all the segments with pars interarticularis defect even those without slippage and not responsible for clinical symptoms. In this study, we tried to study the necessity of the preventative long-segment surgery for the defected segment without slippage in treatment of multi-level spondylolysis patients from a biome...

OBJECTIVE Although trunk muscles in the lumbar spine preserve spinal stability and motility, little is known about the relationship between trunk muscles and spinal fusion rate. The aim of the present study is to evaluate the correlation between trunk muscles cross sectional area (MCSA) and fusion rate after posterior lumbar interbody fusion (PLIF) using stand-alone cages. METHODS A total of ...

STUDY DESIGN A retrospective study. OBJECTIVE The purpose of this study was to investigate: (1) patient-based surgical outcomes of posterior lumbar interbody fusion (PLIF); (2) correlations between patient-based surgical outcomes and surgeon-based surgical outcomes; (3) factors associated with patient satisfaction. SUMMARY OF BACKGROUND DATA There have been no reports of patient-based surgi...

Abstract In recent years, conditioned particle image velocimetry (CPIV) has attracted much attention for flame front extraction. It is an economical and straightforward technique because the can be obtained simply from Mie-scattering images. current work, hydroxyl planar laser-induced fluorescence (OH-PLIF) measurements were taken simultaneously to study applicability of CPIV under conditions w...
