BACKGROUND The purpose of this study aimed to assess preoperative risk factors for the incidence of deep venous thromboembolism in patients undergoing posterior lumbar interbody fusion (PLIF). METHODS The diagnosis of preoperative deep vein thrombosis (DVT) was confirmed by Doppler ultrasonography. To examine the preoperative risk factors for DVT admitted for PLIF, comparative analysis of the...

This paper presents some experimental results concerning the collective behavior of a colony of PLIF (Piezo Light Intelligent Flea) microrobots. An introduction to the peculiarities of piezoelectric PLIF microrobots is given, and then the results of co-operation by three robots are illustrated in both simulation and a real application. From the results it emerges that the strategy implemented i...

Background & Aim: The purpose of this study was to evaluate and compare the pain of patients with spondylolisthesis who had undergone either of the surgery techniques: posterolateral fusion (PLF) or posterior lumbar interbody fusion (PLIF). Methods & Materials/Patients: In a prospective observational study, 102 surgical candidates with low grade degenerative and isthmic spondylolisthesis were e...

Experiments have been carried out to quantify the mixing induced by the interaction of a weak shock wave with a cylindrical volume of a gas (helium) that is lighter than its surroundings (air). In these experiments a round laminar jet was used to produce the light-gas cylinder, and planar laser-induced fluorescence (PLIF) , utilizing a fluorescent tracer (biacetyl) mixed with the helium, was us...

Recently, we have completed the development of an The ability to obtain quantitative planar laserincorporates a production fuel injector and is capable of induced fluorescence (PLIF) measurements in a highoperating at pressures up to 50 atm with preheated air. pressure combustor would represent a significant This facility allows laser-based imaging techniques to be advance in the application of...

AIM Although conventional posterior lumbar interbody fusion (PLIF) using pedicle screws provides successful outcomes, pedicle screw related complications are sometimes noted. SPIRE? was invented as an interspinous fixation device (ISD) to replace pedicle screw. The aim of this study is to evaluate the clinical and radiological outcomes in patients who underwent unilateral PLIF using SPIRE? comp...

STUDY DESIGN Clinical case series. PURPOSE In the posterior lumbar interbody fusion (PLIF) procedure in our institute, the cephalad screw trajectory follows a mediolateral and caudocephalad directed path according to the original cortical bone trajectory (CBT) method. However, the starting point of the caudal screw is at the medial border of the pedicle on an articular surface of the superior...

STUDY DESIGN A retrospective study. PURPOSE An en bloc partial laminectomy and posterior lumbar interbody fusion (PLIF) in spinal stenosis patients with severe foraminal narrowing has a shorter operation time, less neural manipulation and allows indirect decompression by restoring the interforaminal height compared to other procedures. This study investigated the efficacy of the procedure. ...

BACKGROUND For the treatment of low back pain, the following three scenarios of posterior lumbar interbody fusion (PLIF) were usually used, i.e., PLIF procedure with autogenous iliac bone (PAIB model), PLIF with cages made of PEEK (PCP model) or titanium (Ti) (PCT model) materiel. But the benefits or adverse effects among the three surgical scenarios were still not fully understood. METHOD Fi...

The successful development and optimization of fusion power sources will depend largely upon learning more about plasma turbulence and its relation to transport. Gaining a greater knowledge of plasma-edge turbulence is key, as the transport of particles near the plasma's edge has a profound effect on global plasma confinement. It is in this region that the boundary values for plasma temperature...
