Treatment of osteopetrosis combined with fracture around femoral internal fixation: a case report

Frontiers in Surgery
Osteopetrosis is a rare disease caused by bone resorption disorders due to a decrease in osteoclasts or functional abnormalities, which can easily lead to secondary fractures. Currently, there are few reports on the treatment of fractures around internal

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Engineered Mycelial Scaffolds With Tunable Ultraviolet Protection, Wettability, Thermal Stability, and Spatial Mechanics

Advanced Engineering Materials, EarlyView.
Fungal mycelia grown into biodegradable scaffolds and infused with titania nanoparticles show enhanced ultraviolet shielding, thermal protection, and surface nonwettability. Properties were tuned by drying methods, revealing structure–function relationships.

A novel fixation method for panfacial fracture using an Ilizarov-type external fixator

Trauma Case Reports, 2019
In general, internal plate fixation is mainly performed in order to reduce multiple facial bone fractures and rarely uses an external fixator. Although it would be ideal to successfully achieve or preserve the occlusal relationship of the upper and lower

On‐Demand Activation of Thin Alginate Shell Encapsulated Volatile Liquid for Untethered Pneumatic Soft Actuation

Advanced Engineering Materials, EarlyView.
Phase‐changing liquids enable untethered pneumatic actuation in soft robotics but suffer from volatility and storage challenges. This work reports a simple method to encapsulate Novec 7000 within micron‐thin alginate shells via in situ injection and ionic crosslinking.

C-arm-assisted internal fixation of pediatric mandibular fracture

The Egyptian Journal of Otolaryngology, 2018
Introduction Dentition is one of the main concerns while managing pediatric mandibular fractures. The aim of this study was to assess the results of the usage of intraoperative images with C-arm to identify and protect the roots of nonerupted teeth ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Pseudoaneurysm of the internal iliac artery caused by proximal femoral nail antirotation following intertrochanteric fracture: a case report

Journal of International Medical Research
Pseudoaneurysm of the internal iliac artery is a very rare complication of intertrochanteric fracture. Here, the case of an 88-year-old female patient, who presented with intense pain following surgery for intertrochanteric fracture of the femur, is ...

Design of a porous biodegradable internal fixation for the treatment of pauwels type III femoral neck fractures

Frontiers in Bioengineering and Biotechnology
Prolonged internal fixation in the femur can cause issues like osteosclerosis and stress masking, which hinder fracture recovery. AZ31b magnesium alloy has already been widely investigated and shown to be biocompatible and biodegradable.
