Numerical Modeling for Shoulder Injury Detection Using Microwave Imaging [PDF]

arXiv, 2023
A portable imaging system for the on-site detection of shoulder injury is necessary to identify its extent and avoid its development to severe condition. Here, firstly a microwave tomography system is introduced using state-of-the-art numerical modeling and parallel computing for imaging different tissues in the shoulder.

Influence of Rotator Cuff Integrity on Loading and Kinematics Before and After Reverse Shoulder Arthroplasty [PDF]

arXiv, 2020
Reverse Shoulder Arthroplasty (RSA) has become a very common procedure for shoulder joint replacement, even for scenarios where an anatomical reconstruction would traditionally be used. In this study, we investigate joint reaction forces and scapular kinematics for rotator cuff tears of different tendons with and without a reverse prosthesis. Available

Geodesically Complete Hyperbolic Structures [PDF]

Math. Proc. Camb. Phil. Soc. 166 (2019) 219-242, 2015
In the first part of this work we explore the geometry of infinite type surfaces and the relationship between its convex core and space of ends. In particular, we show that a geodesically complete hyperbolic surface is made up of its convex core with funnels attached along the simple closed geodesic components and half-planes attached along simple open

High‐Performance 3D Printed Mechanically Interlocked Soft–Hard Interfaces of Hydrogels and Polylactide

Advanced Materials Technologies, EarlyView.
In this work, a methodology is presented for the design, fabrication and characterization of soft–hard interfaces consisting of extremely soft hydrogel biomaterials, and much harder rigid polymeric biomaterials. This approach enables the production of interfaces with performances close to predicted values, with applications in biomaterial fabrication ...

Comparing the Efficacy of Anatomical Locked Plate Fixation with Coracoclavicular Ligament Augmentation to Hook Plate Fixation in Treating Distal Clavicle Fractures

Orthopaedic Surgery, Volume 14, Issue 12, Page 3358-3366, December 2022., 2022
For the distal clavicle fracture when the coracoclavicular ligament is disrupted, anatomical locked plate fixation with coracoclavicular ligament augmentation brought better shoulder function and less pain than the hook plate fixation in short‐time follow‐up.

Biomimetic Microstructured Scaffold with Release of Re‐Modified Teriparatide for Osteoporotic Tendon‐to‐Bone Regeneration via Balancing Bone Homeostasis

Advanced Science, EarlyView.
This study develops RPTH by re‐modifying teriparatide and designs a biomimetic microstructured scaffold (BMRP) loaded with RPTH to address osteoporotic tendon‐to‐bone interface repair. The BMRP restores tissue architecture by balancing bone homeostasis and remodeling the microstructure, achieving functional recovery in an osteoporotic rotator cuff tear
