Inroads Toward Robot-Assisted Internal Fixation of Bone Fractures Using a Bendable Medical Screw and the Curved Drilling Technique [PDF]
arXiv, 2018 Internal fixation is a common orthopedic procedure in which a rigid screw is used to fix fragments of a fractured bone together and expedite the healing process. However, the rigidity of the screw, geometry of the fractured anatomy (e.g. femur and pelvis), and patient age can cause an array of complications during screw placement, such as improper ...

Formation and mechanics of fire ant rafts as an active self-healing membrane [PDF]
arXiv, 2023 The unique ability of fire ants to form a raft to survive flooding rain has enchanted biologists as well as researchers in other disciplines. It has been established during the last decade that an aggregation of fire ants exhibits viscoelasticity with respect to external compression and shearing among numerous unusual mechanical properties. In addition

Cyclical micromovement and fracture healing [PDF]
The Journal of Bone and Joint Surgery. British volume, 1995 We studied 56 patients with fractures of the tibial shaft in a multicentre prospective randomised trial of three methods of external fixation. Group I was treated with a fixator which was unlocked at 4 to 6 weeks to allow free axial compression (axial dynamisation) with weight-bearing. Group II was treated with a fixator that was similarly unlocked at

Advanced Engineering Materials, EarlyView.In this study, how friction‐welding parameters (rotational speed, etc.) affect the morphology, distribution, and local thickness of the intermetallic compound layer (IMC‐layer) in friction‐welded steel‐aluminum hybrid components is investigated. In the results, it is shown that lower speeds (700 rpm) lead to a more uniform, thinner IMC‐layer (<0.5 μm),

Structured functional regression models for high-dimensional spatial spectroscopy data [PDF]
arXiv, 2013 Modeling and analysis of spectroscopy data is an active area of research with applications to chemistry and biology. This paper focuses on analyzing Raman spectra obtained from a bone fracture healing experiment, although the functional regression model for predicting a scalar response from high-dimensional tensors can be applied to any spectroscopy ...

Journal of Bone and Joint Surgery. American volume, 2016 BACKGROUND Axial dynamization of fractures can promote healing, and overly stiff fixation can suppress healing. A novel technology, termed active plating, provides controlled axial dynamization by the elastic suspension of locking holes within the plate.

Current Trends and Future Perspective for Cold Spray Metal‐Ceramic Composites
Advanced Engineering Materials, EarlyView.The use of cold spray (CS) technology for creating cermet deposits, combining ceramic and metallic components, is advancing rapidly. Cermets offer excellent temperature handling and erosion resistance for diverse applications. This review outlines the current state of the art, focusing on the deposition dynamics and strategies to optimize the ...

Accelerated fracture healing with teriparatide [PDF]
Archives of Endocrinology and Metabolism, 2015 On December 2, 2013, it was called our attention that the case report () contained few paragraphs that bear a likeness to a further review (). This occurred inadvertently when we entrusted the literature and a draft of this review () to others co-authors. Although we were not aware of theses similarities between the case report and this review.

Impact of Surface Roughness on the Yield Drop of Hot‐Rolled AZX311 Mg Alloy
Advanced Engineering Materials, EarlyView.Rough‐surfaced AZX311 Mg alloy samples have significantly lower yield strength than polished ones due to stress concentrators forming at V‐notch irregularities. Surface profilometry confirms higher Ra values for rough samples. Highest hardness values were observed near scratched surfaces, indicating strain localization effects near the rough surface ...
