Dynamic Micromechanical Characterization of 3D Printed Bone In Vitro Models Manufactured via Vat Photopolymerization

Advanced Functional Materials, EarlyView.
This study presents a novel approach to designing and fabricating high‐porosity 3D‐printed scaffolds using a customized resin. Scaffold geometry, cellular interactions, and mechanical properties are analyzed to demonstrate these engineered bone models.

Characterization of Marcellus Shale Fracture Properties through Size Effect Tests and Computations [PDF]

Rock Mechanics and Rock Engineering 52.1 (2019): 1-18, 2017
Mechanical characterization of shale-like rocks requires understanding the scaling of the measured properties to enable the extrapolation from small scale laboratory tests to field study. In this paper, the size effect of Marcellus shale was analyzed, and the fracture properties were obtained through size effect tests.

FACTORS ASSOCIATED WITH THE DEVELOPMENT OF EARLY INFECTION AFTER SURGICAL TREATMENT OF FRACTURES [PDF]

Acta Ortopédica Brasileira, 2018
Objective: Infection after the internal fixation of fractures is a major complication. Early infection is particularly challenging, because it occurs when the fracture is not yet united. The objective of this study is to identify possible factors related

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

Advanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Posterior Ankle Arthroscopic Reduction With Internal Fixation

Arthroscopy Techniques, 2016
Current surgical techniques in ankle fracture management now include arthroscopic-assisted reduction and internal fixation. The need for minimally invasive fracture reduction techniques, which preserve soft tissue envelops and assists in overall anatomic

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

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 ...

Hoffa's fracture of the medial femoral condyle in a child treated with open reduction and internal fixation: A case report

Trauma Case Reports, 2018
Background: Hoffa's fracture is a coronal oriented fracture of the femoral condyles. Isolated coronal fracture of medial femoral condyle with intact lateral femoral condyle is extremely rare in the pediatric patients. There are only few cases of a medial

Inorganic Dielectric Materials Coupling Micro‐/Nanoarchitectures for State‐of‐the‐Art Biomechanical‐to‐Electrical Energy Conversion Devices

Advanced Materials, EarlyView.
Biomechanical‐to‐electrical energy conversion devices are uniquely suited for self‐driven physiological information monitoring and powering human–computer interaction systems. These devices based on micro‐/nanoarchitectured inorganic dielectric materials (MNIDMs) have shown ultrahigh electromechanical performance and thus great potential for practical ...
