Biomechanical effects of internal fixation with self-lock compression anti-rotation blade for Pauwels type III femoral neck fractures: a comparative finite element analysis

BMC Musculoskeletal Disorders, 2023
Background Self-lock compression anti-rotation blade (SCAB) is a novel internal fixation implant for femoral neck fractures (FNF). We conducted this finite element analysis study to evaluate the biomechanical performances of SCAB combined with a ...

Generic Adaptation by Fast Chaotic Exploration and Slow Feedback Fixation [PDF]

arXiv, 2022
Living systems adapt to various environmental conditions by changing their internal states. Inspired by gene expression and epigenetic modification dynamics, we herein propose a generic mechanism for adaptation by combining fast oscillatory dynamics and a slower feedback fixation process. Through extensive model simulations, we reveal that fast chaotic

Is removal of the internal fixation after successful intervertebral fusion necessary? A case–control study based on patient-reported quality of life

Journal of Orthopaedic Surgery and Research, 2022
Background Intervertebral fusion and internal fixation are often applied to patients with lumbar spinal disease. Whether to remove the internal fixation after successful fusion remains uncertain, but such a question needs to be explored in light of ...

Dual mobility total hip arthroplasty for salvaging failed internal fixation for neck of femur fractures

Journal of Orthopaedics, Trauma and Rehabilitation, 2020
Internal fixation is commonly used to treat fractures in the hip. However, failure of proximal femoral fracture fixation is common and treated with total hip replacement (THR). The aim of this study is to present our midterm results of dual mobility (DM)

Distal tibial pilon fractures (AO/OTA type B, and C) treated with the external skeletal and minimal internal fixation method [PDF]

Vojnosanitetski Pregled, 2013
Background/Aim. Distal tibial pilon fractures include extra-articular fractures of the tibial metaphysis and the more severe intra-articular tibial pilon fractures. There is no universal method for treating distal tibial pilon fractures.

Dual-Arm Construction Robot for Automatic Fixation of Structural Parts to Concrete Surfaces in Narrow Environments [PDF]

2023 IEEE/SICE International Symposium on System Integration (SII), Atlanta, GA, USA, 2023, pp. 1-7
Fixation of structural parts to concrete is a repetitive, heavy-duty, and time-consuming task that requires automation due to the lack of skilled construction workers. Previously developed automation techniques have not achieved the complete fixation of structural parts and are difficult to implement in narrow construction environments.

Classifying Eye-Tracking Data Using Saliency Maps [PDF]

arXiv, 2020
A plethora of research in the literature shows how human eye fixation pattern varies depending on different factors, including genetics, age, social functioning, cognitive functioning, and so on. Analysis of these variations in visual attention has already elicited two potential research avenues: 1) determining the physiological or psychological state ...
