Common calcaneal avulsion fracture [PDF]
American Journal of Roentgenology, 1980 An avulsion fracture on the dorsolateral aspect of the calcaneus at the origin of the extensor digitorum brevis muscle was identified after inversion injuries of the ankle. The avulsion occurred in 10% of emergency room patients with clinically suspected ankle fractures.

Outcome of Isolated PCL Tibial Avulsion Fractures Treated with Cannulated Cancellous Screw Fixation
Journal of Orthopedic and Spine Trauma, 2022 Background: The posterior cruciate ligament (PCL) presents commonly as avulsion fractures from the tibial attachment site. Isolated tears of the PCL can be caused by a fall on the flexed knee or dashboard injury in road traffic accident.

Multi-scale approach to invasion percolation of rock fracture networks [PDF]
Journal of Hydrology 519, 353 (2014), 2014 A multi-scale scheme for the invasion percolation of rock fracture networks with heterogeneous fracture aperture fields is proposed. Inside fractures, fluid transport is calculated on the finest scale and found to be localized in channels as a consequence of the aperture field. The channel network is characterized and reduced to a vectorized artificial

Hydraulic Fracture Propagation in Naturally Fractured Reservoirs: Complex Fracture or Fracture Networks [PDF]
, 2019 Understanding the behavior of fluid-driven hydraulic fracture in naturally fractured reservoirs is crucial in the development of geothermal energy and unconventional reservoirs. This study presents a fully-coupled numerical model to investigate hydraulic propagation in naturally fractured reservoirs, along with a comprehensive discussion on field ...

Imaging findings at the quadrangular joint in carpal boss [PDF]
, 2017 A carpal boss was initially described as a bony, sometimes painful mass at the quadrangular joint. Clinical examination and plain radiography will usually reveal the diagnosis. US and CT may add information.

Fracture Model Reduction and Optimization for Forchheimer Flows in Reservoir [PDF]
J. Math. Phys. 60, 051504 (2019), 2017 In this study, we analyze the flow filtration process of slightly compressible fluids in fractured porous media. We model the coupled fractured porous media system, where the linear Darcy flow is considered in porous media and the nonlinear Forchheimer equation is used inside the fracture.

Enhancing Understanding of Hydraulic Fracture Tip Advancement through Inversion of Low-Frequency Distributed Acoustic Sensing Data [PDF]
arXiv, 2023 Characterizing the fluid-driven fracture tip advancing process presents a significant challenge due to the difficulty of replicating real-world conditions in laboratory experiments and the lack of precise field measurements. However, recent advances in low-frequency distributed acoustic sensing (LF-DAS) technology offer new opportunities to investigate
