The analysis of a flow pattern in cerebral aneurysms and the effect of strut shapes and stent porosity in 2D and 3D model are presented in this paper. The efficiency of a stent is related to several parameters, including porosity and stent strut shapes. The goal of this paper is to identify numerically how the stent strut shape and the porosity affect the hemodynamics properties of the flow ins...

When surgical decompression of cervical spine is considered, multilevel cervical corpectomy with long strut grafts is the preferred treatment. This procedure is used in a variety of pathologies including degenerative disease, tumors, trauma and infection. Corpectomy with interbody grafting helps in adequate spinal canal and neural decompression compared to multilevel discectomy, which could be ...

The drum-shaped honeycomb-type cable dome departs from traditional concepts and incorporates the idea of multiple strut configurations. It is most diverse type structure. Both cables struts serve as main load-bearing components. Analyzing effects local component failure crucial for designing large-scale domes able to resist continuous collapse. A numerical analysis model using ANSYS finite elem...

Delayed endograft metallic strut failures detected in vivo with multidetector row computed tomography (MDCT) are reported in two patients who underwent endovascular abdominal aortic aneurysm repair with AneuRx and Talent endografts. In both instances, nitinol fractures were associated with proximal migration and type I endoleak. In both cases, the metallic strut fractures were detected with tra...

BACKGROUND Re-establishing nasal tip projection is one of the main objectives in secondary rhinoplasty. The columellar strut is used as a basic element for support and the septal cartilage graft as the first choice for reconstruction. Nevertheless, the septal cartilage is often missing in this category of patient because of previous surgery, obliging the surgeon to seek a safe, effective, and v...

Using the notion of thermodynamic length, first law thermodynamics is consistently derived for two binary configurations equal Kerr-Newman black holes separated by a massless strut. Like in electrostatic systems Reissner-Nordstr\"om and stationary vacuum Kerr considered earlier, length $\ell$ turns out to be defined same simple formula $\ell=L\exp(\gamma_0)$, $L$ being coordinate strut $\gamma_...

BACKGROUND Echocardiographic imaging of a stented valve bioprosthesis can reveal apparent inward deflection of one or more struts. It could be assumed that this finding is related to actual strut distortion as opposed to an artifact of off-axis imaging. OBJECTIVE To determine whether normal (nondistorted) bioprosthetic struts can appear by artifact to be bent inward on two-dimensional echocar...

BACKGROUND Nasal tip support is an essential consideration for rhinoplasty in East Asians. There are many techniques to improve tip projection, and among them, the columellar strut is the most popular technique. However, the conventional design is less supportive for rotating the tip. The amount of harvestable septal cartilage is relatively small in East Asians. For an optimal outcome, we propo...

BACKGROUND The proximal femur is one of the most common sites involved by fibrous dysplasia. In cases with mild deformity that does not require corrective surgery, occasional patients suffer sustained pain because of repeated microfractures. This study aimed to clarify the outcomes of surgery with autogenous fibular cortical strut grafting and compression hip screw fixation. METHODS Since 200...
