The instability of water-sediment flow in fractures can easily induce disasters. Therefore, it is great significance for the prevention and control inrush to study two-phase fractures. Based on theory, a model system was established. Ansys Fluent software used characteristics smooth rough spatial-temporal evolution laws were studied; results indicated that they did not change with time fracture...

The management of thoracolumbar burst fractures remains challenging. Ideally, it should effectively correct the deformity, induce neurological recovery, allow early mobilization and return to work, and be associated with minimal risk of complication. This article reviews the related studies reporting their clinical data for the management of thoracolumbar burst fractures, discusses the most sui...

background: in children, inappropriate treatment of open femoral fractures may induce several complications. a few studies have compared the external fixator with flexible intramedullary nails in high-grade open femoral fractures of children. the present study aims at comparing results of these two treatment methods in open femoral fractures. methods: in this descriptive analytical study, 27 pa...

the painful nature of fractures has made it inevitable to use various anesthetic techniques to reduce or immobilize fractured parts. in the present study, axillary nerve block was compared with intravenous midazolam/fentanyl to induce anesthesia for painless reduction of upper extremity fractures. the subjects in the present clinical trial consisted of 60 patients with upper extremity fractures...

Distal and tibial pilon fractures often are difficult to treat due to soft-tissue damage from high-energy trauma. Classical surgical treatment may produce additional trauma, eg, periosteal stripping and microcirculatory damage, which frequently induce infection, nonunion, or both. This article presents minimally invasive plate osteosynthesis as a treatment method for these types of fractures. M...

Computed tomography (CT) scans were performed on samples of an outburst-prone coal seam at different loading stages. The area and roundness the CT images used to quantify degree macroscopic deformation under loads. A spatial matching algorithm was calculate three-dimensional (3D) displacement fields regions interest (ROIs, containing primary fractures, minerals, only coal) presence fractures mi...

Abstract Fractures contribute to bulk elastic anisotropy of many materials in the Earth. This includes glaciers and ice sheets, whose fracture state controls routing water base thus large-scale flow. Here we use anisotropy-induced shear wave splitting characterize structure probe subsurface drainage beneath a seismometer network on an Alpine glacier. Shear observations reveal diurnal variations...

hoffa fracture is a rare injury consisting of unicondylar tangential posterior fracture of the distal femur and only very few cases have been reported in the literature. these fractures are due to high energy trauma and conservative treatment generally yields poor results, but rigid internal fixation allows early functional rehabilitation and decreases the incidence of complications. the purpos...
