A series of 123 patients suffering traumatic spondylolisthesis of the axis is reported. This lesion is associated with extension and axial loading injury, and there is a high incidence of injuries of the face or scalp and of associated fractures of the upper cervical spine. There is a low incidence of neurological injury, which seems paradoxical in the presence of what appears to be gross insta...

Abstract In the present work, solutions are recapitulated according to theory of elasticity for deformations an adhesive spherical inhomogeneity in infinite matrix under remote uniform axial and axial-symmetrical radial tension. Stress fields at interface provided, too. It is shown that sphere deformed a spheroid any loading cases considered. Due axial-symmetric setup problem, deformation fully...

The main objective of this work focuses on an electromagnetic analysis axial flux topology machine with mixed excitation system to meet the requirements electric traction system, whose speed ratio in field weakening region is 1:2. methodology employed consists elaboration a magnetic equivalent circuit and subsequent simulation device using Finite Element Method via numerical solving software.

this paper concerns the design and analysis, of a ball type continuously variable transmission, (b-cvt). this b-cvt has a simple kinematic structure, and same as a toroidal cvt, transmits power by friction on the contact points between input and output discs, that are connected to each other by balls. after, a brief introduction of our b-cvt structure, the performance and traction efficiency of...

PURPOSE To investigate changes of the axial length in normal eyes and highly myopic eyes and influence of myopic macular complications in Japanese adults. STUDY DESIGN Retrospective longitudinal case series. METHODS The changes in the axial length of 316 eyes from 316 patients (mean age, 63.8 ± 9.0 years; range, 34-82; 240 females) examined using IOLMaster with a follow-up period of at leas...

Idiopathic pulmonary fibrosis (IPF) is a progressive and lethal pulmonary fibrotic lung disease. The diagnostic histological changes are called usual interstitial pneumonia and are characterized by histological temporal heterogeneity, whereby normal lung tissue is interspersed with interstitial fibrosis, honeycomb cysts and fibroblast foci. Pulmonary functions show restricted volumes and capaci...

Odontoid type I fracture is an avulsion fracture of the odontoid tip resulting from forceful distraction of the alar ligament and has been reported only in a few rare occasions. We have recently encountered an odontoid type I fracture complicated with atlantoaxial dislocation in an 18-year-old male motorcycle rider sustaining neck injury in a crash. An accurate diagnosis was achieved with axial...

OBJECTIVE To determine the surgical outcome of patients with axial cervical spine fractures. METHODS The study was conducted at the Spine Unit of Hayatabad Medical Complex, Peshawar, and Aman Hospital, Peshawar, from January 2012 to March 2013. Patients with sub-axial cervical spine fractures were treated surgically. The outcome was measured using Visual Analogue Score, Neck Disability Index,...
