Mesenchymal Stem Cells‐Derived Extracellular Vesicles Mimetics as Osteoinductive Mediators for Bone Healing

Advanced Functional Materials, EarlyView.
Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.

Visual Attention Based Cognitive Human-Robot Collaboration for Pedicle Screw Placement in Robot-Assisted Orthopedic Surgery [PDF]

Current orthopedic robotic systems largely focus on navigation, aiding surgeons in positioning a guiding tube but still requiring manual drilling and screw placement. The automation of this task not only demands high precision and safety due to the intricate physical interactions between the surgical tool and bone but also poses significant risks when ...

"Surprise" Out-of-network Billing in Orthopedic Surgery: Charges From Surprising Sources.

Annals of Surgery, 2020
I n 2019, lawmakers in both the Senate and House of Representatives proposed multiple bills to end surprise medical billing. A surprise medical bill is a charge from an out-of-network clinician that is not anticipated by the patient at the time of ...

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Masking Effects in Combined Hardness and Stiffness Rendering Using an Encountered-Type Haptic Display [PDF]

arXiv, 2021
Rendering stable hard surfaces is an important problem in haptics for many tasks, including training simulators for orthopedic surgery or dentistry. Current impedance devices cannot provide enough force and stiffness to render a wall, and the high friction and inertia of admittance devices make it difficult to render free space.

Soft Pneumatic Device Designed to Mimic the Periosteal Environment for Regulating the Fate of Mesenchymal Stem Cells

Advanced Healthcare Materials, EarlyView.
This study presents a custom‐made soft pneumatic device (SPD) that mimics complex mechanical forces and fluid flow to enhance in vitro cell differentiation. It shows that low mechanotransduction promotes MSC differentiation into osteoprogenitor cells, while high mechanotransduction causes structural disruptions and cell detachment, providing new ...

An Intervertebral Disc (IVD) Regeneration Model Using Human Nucleus Pulposus Cells (iHNPCs) and Annulus Fibrosus Cells (iHAFCs)

Advanced Healthcare Materials, EarlyView.
This study investigates hTert‐immortalized human nucleus pulposus (iHNPCs) and annulus fibrosus (iHAFCs) cells for intervertebral disc (IVD) regeneration and spinal fusion models. A 3D‐printed citrate‐based scaffold loaded with BMP9‐stimulated iHAFCs and BMP2‐stimulated iHNPCs effectively promotes bone and cartilage formation, mimicking the IVD ...
