A Comprehensive Weightbearing Computed Tomography Study on Patients With Hallux Valgus: Exploring Multiplanar Deformity Interrelationships.

Background: Hallux valgus (HV) is a complex, multiplanar deformity. In this study, we examined the interrelationships between various components of this deformity using weightbearing computed tomography (WBCT). We hypothesized that the severity of traditional axial plane deformities would correlate with malpositioning of the metatarsosesamoid complex, first-ray coronal rotational deformity, and malalignment of the hindfoot and midfoot.

A Finite Element Method for Modeling Diffusion and Drug Release from Nanocellulose/Nanoporous Silicon Composites.

: A previous study investigated the in vitro release of methylene blue (MB), a widely used cationic dye in biomedical applications, from nanocellulose/nanoporous silicon (NC/nPSi) composites under conditions simulating body fluids. The results showed that MB release rates varied significantly with the nPSi concentration in the composite, highlighting its potential for controlled drug delivery. To further analyze the relationship between diffusion dynamics and the MB concentration, this study developed a finite element (FE) method to solve Fick's equations governing the drug delivery system.
