Slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. In slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. Therefore, accurate reproduction of the spatial variability in ...

The 10.6 km long Sabzkuh water conveyance tunnel is currently under construction in High Zagros structural zone, located in western Iran, has used conventional (in section T1) and mechanized (in section T2) methods. The section T1 of the tunnel driven through alluvial geological units with great complexity in an area high potential for sliding and water-bearing fault which has made the excavati...

Creation of the femoral tunnel in anterior cruciate ligament (ACL) reconstruction via the anteromedial portal can reproducibly achieve femoral tunnel positioning at the center of the femoral ACL footprint. Anteromedial portal drilling requires knee hyperflexion, which is awkward to perform. Knee hyperflexion to 120° can easily be achieved in the figure-4 position for femoral tunnel drilling via...

A wind tunnel simulation requires high-performance computing power like supercomputers and deep knowledge of this subject. Those requirements make win tunnel simulation difficult. Grid technology will make these difficulties simpler by providing easy to use grid web portal. By using grid web portal, scientist can execute simulation and access to highperformance computing power without any serio...

Graft-tunnel mismatch of the bone-patellar tendon-bone (BPTB) graft is a major concern during anatomical anterior cruciate ligament (ACL) reconstruction if the femoral tunnel is positioned using a far medial portal technique, as the femoral tunnel tends to be shorter compared with that positioned using a transtibial portal technique. This study describes an accurate method of calculating the id...

Incorrect bone tunnel position, particularly on the femoral side, is a frequent cause of failed anterior cruciate ligament reconstruction. Several studies have reported that drilling the femoral tunnel through the anteromedial portal allows a more anatomical placement on the lateral femoral condyle and higher knee stability than does transtibial reconstruction.In the current study, the femoral ...

Background. Carpal tunnel syndrome, the most common peripheral neuropathy, is caused by increased carpal tunnel pressure and decreased carpal tunnel volume. The aim of our study was to evaluate early results in single-portal endoscopic carpal tunnel release for the surgical treatment of carpal tunnel syndrome. Material and methods. The population included 67 patients with 80 hands operated usin...

The purpose of this study was to compare the accuracy and reproducibility of the femoral tunnel location among 3 different viewing techniques used during outside-in anterior cruciate ligament (ACL) reconstruction with 3- dimensional (3-D) computed tomography (CT): (1) an anterolateral (AL) or anteromedial (AM) portal with a 30° arthroscope (A group) vs (2) a posterolateral (PL) portal with a 70...

There is growing evidence that anatomic placement of the femoral tunnel in anterior cruciate ligament reconstruction confers biomechanical advantages over the traditional tunnel position. The anteromedial portal technique for anatomic anterior cruciate ligament reconstruction has many well-described technical challenges. This article describes the translateral all-inside technique, which produc...
