The story of a deformed leprous foot

Leprosy Review, 2016
Eccrine syringofibroadenoma (ESFA) is a rare adnexal tumour of eccrine ductal proliferation. A 50 year old treated case of leprosy presented with a chronic non healing ulcer of 5 years duration on the deformity laden right foot. Multiple verrucous papules and plaques were seen surrounding the ulcer which showed histopathological findings consistent ...

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Association between subtalar articular surface typing and flat foot deformity: which type is more likely to cause flat foot deformity

BMC Musculoskeletal Disorders, 2021
Background Previous studies have shown a wide range of anatomical classifications of the subtalar joint (STJ) in the population and this is related to the different force line structures of the foot.

External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

Advanced Engineering Materials, EarlyView.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

Non-metal locking construct for hindfoot and ankle arthrodesis using intramedullary fibular allograft strut in cases with prior infection

Foot & Ankle Surgery: Techniques, Reports & Cases
Few reports have been published regarding septic ankle or charcot neuroarthropathy deformities with a fibular strut allograft construct. A retrospective review was conducted to examine the radiographic and clinical outcomes of using fibular allograft ...

Extraction of the Proximal Phalanx: A New Option in Surgical Treatment of the Crossover Second Toe

Case Reports in Orthopedics, 2020
One of the biggest and commonest problems that is seen and treated by foot and ankle surgeons is the deformity where the second toe crosses over the hallux. According to available literature, this is the first published case of extraction of the proximal

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Investigation on the site of coronal deformities in Hallux valgus

Scientific Reports, 2023
Hallux valgus (HV) is a common foot deformity that is more prevalent in females, characterised by abnormal adduction of the first metatarsal (MT) and valgus deviation of the phalanx on the transverse plane.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.
