Biomechanical stability of coronoid fractures with different fragment heights in the terrible triad of the elbow: CT measurement and finite element analysis

Frontiers in Bioengineering and Biotechnology
BackgroundCoronoid fracture height is an independent factor influencing elbow joint stability. In the terrible triad of the elbow, coronoid fractures are typically manifest as small transverse fractures involving the coronoid tip.

Conformal Thermoreversible Gelatin‐Based Gel for High‐Fidelity Electrophysiological Recording and Acute Peripheral Nerve Interfacing

Advanced Materials, EarlyView.
A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Combination of Galeazzi Fracture, Fracture Ulnar Head, and Ipsilateral Posterior Elbow Dislocation: A Rare Case Report

Journal of Bone and Joint Diseases, 2022
Posterior elbow dislocation, ipsilateral Galeazzi fracture, and fracture of ulnar head is a very unusual injury pattern. In the literature, only eight such cases have been reported. Another such case of a 24-year-old woman is being reported by us.

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Isolated Trochlea Fracture: A Rare Case Report

Journal of Orthopedic and Spine Trauma, 2023
Background: Trochlea fracture usually happens with other fractures such as capitellum fracture or medial or lateral condyle fracture and isolated trochlea fracture is very rare because of its location and there are only a few cases of isolated trochlea ...
