A reconfigurable seven-link multi-mode external-fixation system for improving emergency limb fracture stabilization efficiency [PDF]

Mechanical Sciences
The traditional external fixation has problems such as a single fixed dimension, limited application range, long fixation time, and heavy weight. A single-function external fixation is unable to meet the various needs of fracture fixation in scenarios ...

Hooked embracing plate for Rolando fracture fixation: a preliminary result

BMC Surgery, 2022
Background Rolando fracture is a comminuted, intra-articular fracture over the metacarpal bone base of the thumb which often leads to joint instability and requirement of surgery.

Associations of Rheumatoid Arthritis Disease Activity with Frailty Over Five Years of Follow‐up

Arthritis Care &Research, Accepted Article.
Objective To evaluate whether rheumatoid arthritis (RA) disease activity is associated with frailty both in cross‐section and longitudinally. Methods Participants within the Veterans Affairs Rheumatoid Arthritis registry enrolled from 2003 to 2022 were included. The exposure was RA disease activity measured by Disease Activity Score in 28‐joints (DAS28)

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
