Biomedicines, 2023 Nondisplaced femoral neck fractures are sometimes misdiagnosed by radiographs, which may deteriorate into displaced fractures. However, few efficient artificial intelligent methods have been reported. We developed an automatic detection method using deep

Permeability Estimates of Self-Affine Fracture Faults Based on Generalization of the Bottle Neck Concept [PDF]
Water Resources Research 46 (2010) W07601, 2010 We propose a method for calculating the effective permeability of two-dimensional self-affine permeability fields based on generalizing the one-dimensional concept of a bottleneck. We test the method on fracture faults where the local permeability field is given by the cube of the aperture field.

PCN ReportsAim Fracture‐related femoral neck displacement is more likely in patients with schizophrenia because of delayed diagnosis, as these patients frequently have less severe fracture‐associated subjective symptoms.

Automated volumetric and statistical shape assessment of cam-type morphology of the femoral head-neck region from 3D magnetic resonance images [PDF]
arXiv, 2021 Femoroacetabular impingement (FAI) cam morphology is routinely assessed using two-dimensional alpha angles which do not provide specific data on cam size characteristics. The purpose of this study is to implement a novel, automated three-dimensional (3D) pipeline, CamMorph, for segmentation and measurement of cam volume, surface area and height from ...

Brittle fracture of polymer transient networks [PDF]
Journal of Rheology 61(6), 1267-1275, 2017, 2017 We study the fracture of reversible double transient networks, constituted of water suspensions of entangled surfactant wormlike micelles reversibly linked by various amounts of telechelic polymers. We provide a state diagram that delineates the regime of fracture without necking of the filament from the regime where no fracture or break-up has been ...

Percolative Mechanism of Aging in Zirconia-Containing Ceramics for Medical Applications [PDF]
Advanced Materials, Volume 15, Issue 6, March, 2003, Pages 507-511, 2018 Recently, several episodes of fracture of zirconia ceramic femoral heads of total hip prostheses have alarmed the medical and scientific community regarding aging problems in zirconia prostheses. Such fractures cause immediate local tissue reactions, which require urgent medical intervention to prevent further complications.

A Computer-Aided Diagnosis System Using Artificial Intelligence for Hip Fractures -Multi-Institutional Joint Development Research- [PDF]
arXiv, 2020 [Objective] To develop a Computer-aided diagnosis (CAD) system for plane frontal hip X-rays with a deep learning model trained on a large dataset collected at multiple centers. [Materials and Methods]. We included 5295 cases with neck fracture or trochanteric fracture who were diagnosed and treated by orthopedic surgeons using plane X-rays or computed ...

A verdadeira fratura do colo do fêmur The real fracture of femoral neck
Acta Ortopédica Brasileira, 2000 Cento e vinte e seis cabeças femorais retiradas durante artroplastias de quadril para tratamento de fraturas do colo do fêmur foram estudadas macroscopicamente e radiograficamente quanto ao traço de fratura e a existência de colo inferior que pode ...

BMC Musculoskeletal Disorders, 2020 Background The incidence of insufficiency fracture (IF) at femoral neck is low, accounting for about 5% of all insufficiency fractures, and IF at bilateral femoral neck is less common with more occurrence in athlete or serviceman.

Cortical thickness mapping to identify focal osteoporosis in patients with hip fracture. [PDF]
PLoS ONE, 2012 BackgroundIndividuals with osteoporosis are predisposed to hip fracture during trips, stumbles or falls, but half of all hip fractures occur in those without generalised osteoporosis.
