The effect of insertion time on the axial pullout strength of anterior vertebral body screws [PDF]

, 2009
Top screw pullout occurs when the screw is under too much axial force to remain secure in the vertebral body. In vitro biomechanical pullout tests are commonly done to find the maximum fixation strength of anterior vertebral body screws.

Anisotropic pullout behavior of bauxite slag-geogrid interfaces

Scientific Reports
This study investigated the anisotropic pullout behavior of dry bauxite slag-geogrid interfaces to address a critical knowledge gap in abandoned bauxite slag deposits reinforcement. Laboratory tests were conducted on coarse sand (slag of 2.5–4.75 mm) and

Achieving High‐Instantaneous Pulse Power in Contact‐Separation TENG via Series Capacitive Voltage Control Architecture

Advanced Science, EarlyView.
Conventional contact‐separation triboelectric nanogenerators generate high voltage but deliver limited power due to premature charge dissipation. Here, a capacitive charge reservoir architecture decouples charge accumulation from discharge triggering, enabling sequential voltage amplification via floating‐layer capacitive coupling.

Achilles Pullout Strength After Open Calcaneoplasty for Haglund’s Syndrome

, 2018
Background: Haglund’s syndrome involves a prominent posterior superior prominence of the calcaneus. If nonoperative management fails, operative management with calcaneoplasty is often needed.

Towards a Compositional Framework for Describing Human Phenotypes

Advanced Science, EarlyView.
The Phenotype Assembly Method (PhenoAM) decomposes phenotype variables into measurable Features and typed Qualifiers, enabling standardized, machine‐readable Phenome Data Elements (PhenoDEs) that preserve measurement context. Applied in the International Human Phenome Project (IHPP), the framework yields 58 371 PhenoDEs and supports component‐level ...

A Transosseous Suture Technique for Rotator Cuff Repair in Patients With Severe Osteoporosis. [PDF]

Arthrosc Tech
Abstract Suture anchor‐based repair is widely regarded as the standard technique for rotator cuff tears; however, in patients with severe osteoporosis, anchor pullout remains a major concern. Classical transosseous rotator cuff repair provides favorable biomechanical strength and avoids anchor‐related complications but has several inherent limitations.

Matrix Rigidity Mechanoprimes Microglia for Inflammation Through Cytoskeletal‐to‐Nuclear Signaling and 3D Spatio‐Epigenomic Remodeling

Advanced Science, EarlyView.
Pathological tissue rigidity mechanoprimes microglia by enhancing actin cytoskeleton–nucleus coupling and chromatin opening at rigidity‐responsive cis‐regulatory elements (mechanoCREs). Subsequent NF‐κB/p65 signaling converges on this permissive regulatory state to amplify inflammatory gene expression and microglial activation.

Arthroscopic Repair of Medial Meniscus Posterior Root Tear: Transtibial Fixation With 2 Lasso-Loop Sutures and 1 Samsung Medical Center Sliding Knot for Tensioning Secured by a Tibial Button. [PDF]

Arthrosc Tech
Abstract Medial meniscus posterior root tears disrupt the circumferential load‐transmission function of the meniscus and negatively affect knee biomechanics. This technical note describes a reliable and reproducible arthroscopic repair technique using 2 lasso‐loop sutures and 1 Samsung Medical Center sliding knot through a single transtibial tunnel ...

Quantifying the Dynamics of Network Detachment Across Scientific, Technological, Commercial, and Pharmacological Domains

Advanced Science, EarlyView.
Across scientific, technological, commercial, and pharmacological domains, individuals and organizations disengage from a previously adopted practice not at random, but as their network neighbors detach. The probability of detachment rises with the number of neighbors who have already disengaged. Preferential detachment reshapes network disintegration,

Tension-Reducing Arthroscopic Rotator Cuff Repair Using High-Strength Suture Tape in a Suspension Bridge Configuration. [PDF]

Arthrosc Tech
Abstract The maturation of arthroscopic techniques has provided patients with rotator cuff tears a minimally invasive treatment option with favorable outcomes; however, the rate of retear remains high. High‐strength suture tape is widely used in procedures such as knee ligament reconstruction and ankle ligament repair, where it enhances the tensile ...
