IMPORTANCE Despite multiple fixation techniques, the optimal method of repairing mandibular angle fractures remains controversial. OBJECTIVE To evaluate the outcomes when using a 3-dimensional, curved strut plate in repair of angle of the mandible fractures. DESIGN Retrospective cohort study. SETTING Level I trauma center at an academic institution in Harris County, Texas. PARTICIPANTS ...

BACKGROUND Three-dimensional design simulations of coronary metallic stents utilizing mathematical and computational algorithms have emerged as important tools for understanding biomechanical stent properties, predicting the interaction of the implanted platform with the adjacent tissue, and informing stent design enhancements. Herein, we demonstrate the hemodynamic implications following virtu...

there have been some experimental tests on hollow curved-steel struts with thin-walled square sections, in order to investigate their general behavior, particularly their capacity for bearing differing loads. one set of square tubes are cold-formed into segments of circular arcs with curvature radii, equal to 4000 mm. different lengths of curved struts are fabricated so as to cover a practical ...

A 56-year-old man, known for type B aortic dissection, was treated 3 years before with a Talent endograft (Medtronic, Minneapolis, USA) in the descending aorta. He presented with tamponade caused by the perforation of the aortic intima by the uncovered stent strut. The ascending aorta and part of the aortic arch were replaced. The operation and recovery were uneventful. To avoid aortic arch dam...

OBJECTIVE To measure the effect of columellar struts and cephalic trim on tip projection and tip rotation using digitized photographs. METHODS Using photographs of 62 patients who underwent external rhinoplasty, we retrospectively analyzed nasal tip projection (the Goode method) and rotation (nasolabial angle) before and after surgery. A cartilaginous strut was used in 36 patients, whereas 26...

this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...

In septal surgery, the surgeon preserves the L-strut, the portion anterior to a vertical line drawn from the rhinion to the anterior nasal spine (ANS) and at least a 1-cm width of the dorsal and caudal septal segment, to decrease the potential for loss of the tip and dorsal nasal support. However, nasal tip collapse and saddle deformities occur occasionally. We utilized a mechanical approach to...

Introducing buckling pattern into straight-walled lattice structure, anovel inspired meta-structure (BILM) was designed and fabricated using polylactic acid (PLA) by three-dimensional (3D) printing technology. The square structure with positive Poisson’s ratio (PPR) is transformed negative (NPR) induction. Curved struts decrease the maximum strain, prohibit strut fracture, increase contact indu...

Masonry infill walls are often used as non-structural elements. According to the past structural failure, ignorance of interaction between infill walls and enclosed frame may lead to the different seismic response for non-ductile building frames. The main contribution of this paper is to analytically investigate the behavior of reinforced concrete with masonry infill panels as participating str...

OBJECTIVES We tested the hypothesis that thinner-strut stents are associated with a reduced rate of restenosis when comparing two stents with different design. BACKGROUND We have previously shown that, for two stents with similar design, the risk for restenosis is dependent on the strut thickness. It is unknown whether strut thickness preserves its relevance as a determinant of restenosis eve...
