3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Experimental analysis of femoral head intraosseous vascular anastomosis in the treatment of porcine subcapital femoral neck fractures

Heliyon
Introduction: Femoral neck fractures are challenging injuries associated with a compromised blood supply to the femoral head, leading to a high risk of avascular necrosis and poor clinical outcomes. This study aimed to investigate the efficacy of femoral

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

Advanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

Research progress in the pathogenesis of hormone-induced femoral head necrosis based on microvessels: a systematic review

Journal of Orthopaedic Surgery and Research
Hormonal necrosis of the femoral head is caused by long-term use of glucocorticoids and other causes of abnormal bone metabolism, lipid metabolism imbalance and blood microcirculation disorders in the femoral head, resulting in bone trabecular fracture ...

Routine Pathologic Examination of the Femoral Head in Total Hip Arthroplasty: A Survey Study of the American Association of Hip and Knee Surgeons

Arthroplasty Today, 2023
Background: Current literature does not provide conclusive evidence on whether routine pathologic examination of femoral heads from total hip arthroplasty is indicated or cost-effective.

Effect of femoral head size and surgical approach on risk of revision for dislocation after total hip arthroplasty

Acta Orthopaedica, 2017
Background and purpose — Recurrent dislocation is the commonest cause of early revision of a total hip arthropasty (THA). We examined the effect of femoral head size and surgical approach on revision rate for dislocation, and for other reasons, after ...

PRELIVE: A Framework for Predicting Lipid Nanoparticles In Vivo Efficacy and Reducing Reliance on Animal Testing

Advanced Functional Materials, EarlyView.
PREdicting LNP In Vivo Efficacy (PRELIVE) framework enables the prediction of lipid nanoparticle (LNPs) organ‐specific delivery through dual modeling approaches. Composition‐based models using formulation parameters and protein corona‐based models using biological fingerprints both achieve high predictive accuracy across multiple organs.
