The alignment between halo spins and the cosmic web is still poorly understood despite being a widely studied topic. Here, we study this within context of tidal torque theory (TTT) deviations from it. To end, analyze evolution shape spin direction proto-haloes, i.e. all volume elements associated to $z=0$ halo, with respect present-day filaments. We find that major axis proto-haloes undergoes c...

We explore the evolution of halo spins in cosmic web using a very large sample dark matter haloes $\Lambda$CDM Planck-Millennium N-body simulation. use NEXUS+ multiscale formalism to identify hierarchy filaments and sheets at several redshifts. find that all times magnitude correlates with environment, being largest filaments, and, for first time, we show it also filament thickness as well angl...

Figure 1. Cervical spine CT demonstrates normal alignment without fracture in a patient who experienced a minor hyperflexion injury. Each year in the United States and Canada, more than 13 million patients are treated for injuries that put them at risk of injury to the cervical spine. Few of these patients have a cervical spine fracture or other serious injury to the neck. It has been common pr...

Spine fractures in patients with ankylosing spondylitis frequently extend to all 3 columns, which can lead to displacement and deformity with severe instability. Cervical spine fractures occasionally cause severe kyphotic deformities, such as chin-on-chest deformities. In such cases, the patients typically exhibit a chronic progression of hyperkyphosis after the traumatic event. This article de...

The proprioceptive system is essential for the control of coordinated movement and posture. Thus, traditionally, study proprioception has focused on its role in motor control. In this review, we present more recent findings other, non-traditional functions system. We focus involvement musculoskeletal development, function pathology, including regulation spinal alignment, bone fracture repair jo...

STUDY DESIGN Case report of 3 thoracic spine fracture-dislocations with complete spinal cord section treated by total vertebrectomy--spine shortening through a posterior approach. OBJECTIVES To assess the usefulness and safety of this surgical technique in the treatment of acute thoracic spine fracture-dislocation. SUMMARY OF BACKGROUND Total vertebrectomy can be used in different nontrauma...

Kinetic magnetic resonance images (kMRIs) of 587 lumbar and 459 cervical spines of symptomatic patients in axially loaded, upright neutral (0 degrees), flexion (40 degrees), and extension (-20 degrees) positions were evaluated. Imaging took 10 to 12 minutes to complete in each position. Cervical kinematics were significantly affected by intervertebral disc degeneration, cervical cord compressio...
