Femoroacetabular impingement after the femoral neck fracture healed in a nonanatomical position [PDF]
Vojnosanitetski Pregled, 2019 Introduction. Femoroacetabular impingement is the result of the pathological conditions in the osseous acetabulum and/or the proximal femur. One of its causes is a non-anatomically healed femoral neck fracture. Case report.

Novel total hip surgery robotic system based on self-localization and optical measurement [PDF]
arXiv, 2022 This paper presents the development and experimental evaluation of a surgical robotic system for total hip arthroplasty (THA). Although existing robotic systems used in joint replacement surgery have achieved some progresses, the robot arm must be situated accurately at the target position during operation, which depends significantly on the experience

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.

Femoral neck fracture after femoral head necrosis: a case report and review of the literature
BMC Musculoskeletal Disorders, 2023 Introduction Pathological fractures of the femoral neck caused by necrosis of the femoral head are extremely rare. Here, we report a rare case of bilateral femoral head osteonecrosis extending to the femoral neck, with bilateral pathological fractures of

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 ...
