The Influence of Gender, Age, and Body Mass Index on Arch Height and Arch Stiffness.
Journal of Foot and Ankle Surgery, 2020Arch structure and arch function play an important role in maintaining balance, bearing body weight, and absorbing ground reaction forces. However, arch structure and arch function are known to vary extensively and may be affected by factors such as ...

Journal of Geotechnical Engineering, 1985
Soil arching action or “bin effect” is usually quantified by use of a horizontal differential element whose support derives in part from Rankine theory. In the 1940's, Krynine mathematically proved this incorrect. The present analysis substitutes a catenary arch describing the path of the minor principal stress, which thus is complementary to a ...

Coarctation and hypoplasia of the aortic arch: Will the arch grow?
The Annals of Thoracic Surgery, 1991Hypoplasia of the transverse aortic arch of various degrees of severity is commonly seen in infants who have coarctation of the aorta. It is more often present when the coarctation is associated with intracardiac lesions that diminish or limit forward flow in the ascending aorta and promote right to left flow through an arterial duct.

Double Aortic Arch with Left Arch Atresia
Heart, Lung and Circulation, 2009A girl, having an echocardiogram suggestive of double aortic arch, underwent a cardiac multidetector computed tomography (MDCT) examination. MDCT revealed double aortic arch with left arch atresia distal to the left subclavian artery. The left common carotid artery and the left subclavian artery arose from the left arch, the right common carotid artery

Total Arch Replacement for a Distal Aortic Arch Aneurysm With Right Aortic Arch
The Annals of Thoracic Surgery, 2007Right-sided aortic arch accompanied by an aberrant origin of the left subclavian artery is rare and seen in 0.05% approximately 0.1% of the population. A 73-year-old woman with this anomaly was admitted to our institution because of the enlargement of the distal aortic arch aneurysm. She also had mild dysphagia.
