Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

open access: yesAdvanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

3D Multicellular Scaffold Based Model for Advancing Bone Disorder Research

open access: yesAdvanced Functional Materials, EarlyView.
A scalable 3D multicellular in vitro bone model engineered by integrating osteoblasts, osteoclasts, and endothelial cells on biodegradable scaffolds. The system recapitulates key features of human bone remodeling and disease pathology. As a proof of concept, the model mimics osteogenesis imperfecta, demonstrating its potential as a physiologically ...

Increased risk of intraoperative and early postoperative periprosthetic femoral fracture with uncemented stems: 7,169 total hip arthroplasties from 8 Danish centers

open access: yesActa Orthopaedica, 2017
Background and purpose — The use of uncemented fixation in total hip arthroplasty (THA) is increasing. Registry studies have indicated an increased risk of revision of uncemented implants due to early periprosthetic femoral fracture.

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

open access: yesAdvanced 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.

Femoral head fractures [PDF]

open access: yesInternational Orthopaedics, 2001
This report includes six patients with femoral head fractures. Five were associated with posterior hip dislocation, of which one also had an ipsilateral trochanteric fracture. All were young adults who had been injured in automobile accidents. The protocol for management, indications for surgery and guidelines for evaluation of results are described.

Influence of associated femoral head fractures on surgical outcomes following osteosynthesis in posterior wall acetabular fractures

open access: yesBMC Musculoskeletal Disorders, 2022
Background To date, no study has compared the surgical outcomes between posterior wall acetabular fractures with and without associated femoral head fractures. Therefore, we evaluated whether an associated femoral head fracture increases the incidence of

3D‐Printed Multidimensional Bionic Mg‐MC/PLGA Composite for Tailored Repair of Segmental Long Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops 3D‐printed Mg‐MC/PLGA scaffolds with varying Mg concentrations (0–20%). The 5% Mg scaffold shows optimal cytocompatibility, osteogenic activity in vitro, and significantly enhances bone regeneration in rabbits, improving bone volume and mechanical strength.

Unstable Pelvic Fractures Associated with Femoral Shaft Fractures: A Retrospective Analysis

open access: yesBiomedical Journal, 2013
Background: Both pelvic fractures and femoral shaft fractures are caused by high-energy injuries. When unstable pelvic fractures and femoral shaft fractures occur concomitantly, the optimal treatment method is controversial.
