BACKGROUND Previous reports have observed differences only in infection rates between posterolateral fusion and posterior lumbar interbody fusion (PLIF). There have been no reports that describe the particular features of surgical site infection (SSI) in PLIF. In this study, we endeavor to identify the distinguishing characteristics and risk factors of SSI in PLIF. METHODS Our study undertook...

Objective: To illustrate a hybrid technique that involves a combination of open decompression and Posterior Lumbar Interbody Fusion (PLIF) and percutaneously placed pedicle screws. This technique allows for PLIF via a midline incision and approach, and decompression without compromise in operative time and visualisation. Furthermore, this approach is proposed to reduce post-operative wound pain...

Simultaneous measurements, such as the combination of particle image velocimetry (PIV) for velocity fields with planar laser induced fluorescence (PLIF) species fields, are widely used in experimental turbulent combustion applications analysis a plethora complex physical processes. Such analyses driven by interpretation spatial correlations between these experimenter. However, also imply some a...

Introduction: Posterior lumbar interbody fusion (PLIF) has produced satisfactory clinical outcomes; however, all previous reports have only included evaluations by surgeon-based methods. The purpose of this study was to investigate patient-based surgical outcomes and the factors associated with patient satisfaction for PLIF. Methods: Patients who underwent PLIF for lumbar spondylolisthesis were...

In this study, we experimentally investigate large-scale vortex structures, fuel-air mixing and reaction processes, which occur in a partially premixed swirl-stabilized ethylene/air flame laboratory-scale gas turbine model combustor. Time-resolved stereo-PIV, OH-PLIF, acetone/PAH-PLIF systems with repetition rate of 10 kHz are used to the behavior at 3 bar pressure an equivalence ratio Φ=1.2. F...

We investigate the feasibility of using a combined absorption – planar laser-induced fluorescence (PLIF) method for measuring nitric oxide (NO) number density in the freestream of a free-piston shock tunnel. The absorption coefficient is determined from the exponential decay in PLIF intensity through a uniform region of flow. The NO density is determined from the measured absorption coefficient...

Recurrence of back or leg pain after discectomy is a well-recognised problem with an incidence of up to 28%. Once conservative measures have failed, several surgical options are available and have been tried with varying degrees of success. In this study, 42 patients with recurrent symptoms after discectomy underwent less invasive posterior lumbar interbody fusion (LI-PLIF). Clinical outcome wa...

Background. Posterior lumbar interbody fusion (PLIF) is a common surgical treatment for degenerative spinal instability, but many surgeons consider obesity a contraindication for elective spinal fusion. The aim of this study was to analyze whether obesity has any influence on hospitalization parameters, change in clinical status, or complications. Methods. In this prospective study, regression ...
