[Three-Dimensional Nonlinear Finite Element Modeling and Analysis of Concomitant Atlanto-Occipital Fusion and Atlantoaxial Joint Dislocation].

Objective: To establish, with finite element technology, a three-dimensional nonlinear finite element model of the normal occipital bone, atlas and axis and a three-dimensional nonlinear finite element model of concomitant atlanto-occipital fusion and atlantoaxial dislocation, providing a biomechanical method for clinical research on the upper cervical spine.

Methods: Finite element analysis was conducted with the CT data of a 27-year-old male volunteer, and a three-dimensional nonlinear finite element model, i.e.

Cerebral Microbleed Burden in Ischemic Stroke Patients on Aspirin: Prospective Cohort of Intracranial Hemorrhage.

This investigation aimed at studying the prevalence of cerebral microbleeds (CMBs), including risk factors and the correlation of CMBs to ischemic stroke (IS) patient end results. Four hundred and fifty-nine acute IS cases were recruited between April 2014 and December 2016. Cerebral microbleeds were analyzed using susceptibility-weighted imaging (SWI) brain MRI scan.

[A Case Report of Ectopic Sweat Duct Ectasia of Conus Medullaris].

A healthy 52-year-old woman presented with 10-days history of back pain. Neurologic testing failed to detect any functional deficits in the upper and lower extremities, and the patient had a full range of cervical spine motion without associated pain. Spinal CT and MRI revealed a well-circumscribed intradural mass located at conus medullaris.
