Injectable and In Situ Hydration‐Reinforced Hybrid Bone Cements for Accelerated Bone Regeneration

Advanced Science, EarlyView.
To enable minimally invasive bone defect repair, an injectable and hydration‐reinforced bone cement (L‐PEGS/CPC) is designed through biomimetic reconstruction. The hydrophilic L‐PEGS organic phase provides abundant nucleation sites, synergizing with its porous architecture to accelerate CPC hydration, thereby endowing the composite with exceptional ...

Adductor canal block versus femoral nerve block for total knee arthroplasty: a meta-analysis of randomized controlled trials

Scientific Reports, 2017
Femoral nerve blocks (FNB) can provide effective pain relief but result in quadriceps weakness with increased risk of falls following total knee arthroplasty (TKA).

Identification and Mechanisms of Osteocyte Subsets Involved in the Pathological Progression of Osteoporosis

Advanced Science, EarlyView.
Osteocyte heterogeneity in bone remains poorly understood. This study identifies six distinct osteocyte subsets in mice, revealing a key subpopulation (BHR‐Ocys) that drives bone loss in osteoporosis. BHR‐Ocys promote osteoclast‐mediated resorption via a novel Sema5a‐Plxna1 signaling axis.

Femoral Nerve Block Intervention in Neck of Femur Fracture (FINOF): a randomised controlled trial

BMJ Open, 2018
Objective Fractured neck of femur is a severely painful condition with significant mortality and morbidity. We investigated whether early and continuous use of femoral nerve block can improve pain on movement and mobility after surgery in older ...

Electrosensitive Heterogeneous Short Fibers via Acousto‐Electric Coupling for Sequential Bone Regeneration in Infectious Defects

Advanced Science, EarlyView.
Electrosensitive heterogeneous short fibers can accurately respond to ultrasonic field regulation through the synergistic interaction of piezoelectric and conductive dual elements. At an ultrasound intensity of 1.5 W cm−2, it can effectively activate bacterial peroxisome and necrotic apoptotic pathway and promote bacterial apoptosis.

Utilization of a Continuous Pericapsular Nerve Group (PENG) Block with an Opioid-Sparing Repair of a Femoral Neck Fracture in a Pediatric Patient

Case Reports in Orthopedics, 2020
In the pediatric population, femoral neck fractures are usually associated with high-impact trauma and often present with pain in the groin area. Regional anesthesia can offer adjunctive therapy for acute pain management.

Stromal Cell‐Mast Cell Communication Orchestrates Anti‐Viral Immunity in the Meninges

Advanced Science, EarlyView.
This study delineates the spatial distribution and postnatal maturation of meningeal mast cells and uncovers their essential role in antiviral immunity. Using genetic models, mast cells are shown to promote CD8⁺ T cell infiltration and viral clearance via IL‐33 receptor signaling and synergistic activation by IL‐33 and ATP from infected stromal cells ...

Reinstating Niche Failure in Diabetic Cranial Defects via Chronotaxic Signal‐Amplifying Fluidic Biomimetic Hydrogel

Advanced Science, EarlyView.
An in situ moldable GelSSO/PDA@SDF hydrogel functions as a chronotaxic signal‐amplifying biomimetic niche to restore regenerative failure in diabetic cranial defects. By sequentially releasing SDF‐1α‐loaded PDA nanoparticles and osteoinductive oligodeoxynucleotides, it orchestrates immunomodulation, progenitor recruitment, angiogenesis, and ...

Osteoclast‐Derived SLIT3 Mediates Osteoarthritis Pain and Degenerative Changes

Advanced Science, EarlyView.
In TMJ‐OA, osteoclasts play a significant role in promoting the growth of sensory nerves at the osteochondral interface. In early OA, TRAP+ osteoclast‐derived SLIT3 induces sensory nerve growth into the condylar cartilage. This nerve growth facilitates the development of pain associated with OA.
