Biportal Endoscopic Intramedullary Debridement for Management of Tibial Osteomyelitis

Arthroscopy Techniques
Chronic osteomyelitis occurs if the bone infection persists for more than 6 weeks. The presence of dead bone (sequestrum) and intramedullary abscess with chronic infected tissue may protect bacteria from the endogenous host immune response and limit the ...

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

Advanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Osseointegração clínica-radiológica do compósito hidroxiapatita-lignina entre implante metálico e tecido ósseo em coelho Clinical-radiographic osseointegration of hydroxyapatite-lignin composite between metallic implant and bone tissue in rabbit

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
Para avaliar o compósito hidroxiapatita-lignina na osseointegração entre implante metálico e o tecido ósseo, foram utilizados 20 coelhos adultos, nos quais foi realizada uma falha óssea na face lateral proximal de ambas as tíbias.

Spontaneous Distal Extrusion of Kuntscher Intramedullary Nail

Case Reports in Orthopedics, 2021
Migration of femoral Kuntscher intramedullary nail (K-nail) proximally or distally within the femoral medullary cavity is a well-known documented complication, but spontaneous extrusion of a distally migrated K-nail is a rare complication. This is a case

Neural Circuits between Nodose Ganglion and Pulmonary Neuroendocrine Cells Regulate Lung Inflammatory Responses

Advanced Science, EarlyView.
TRPA1+αCGRP+ sensory neurons in the nodose ganglion detect external insults such as lipopolysaccharide (LPS) and interact directly with pulmonary neuroendocrine cells (PNECs), promoting their activation and proliferation. This neural‐epithelial interaction amplifies lung inflammation.

Immunomodulatory Hydrogel Coating with SeNPs and Lithium Silicate Synergistically Promotes Osseointegration and Prevents Infection on Titanium Implants

Advanced Science, EarlyView.
This study introduces a multifunctional hydrogel coating (Lap‐CMCSMA/GelMA@SeNPs) that scavenges ROS, modulates immune responses, and shows strong antibacterial activity. It effectively restores the peri‐implant microenvironment. The coating exhibits excellent biocompatibility and promotes osteogenic differentiation.
