Exploring the displacement characteristics of Garden III femoral neck fractures and the reliability, validity, and value of the anteroposterior Garden Index in assessing displacement severity

Journal of Orthopaedic Surgery and Research, 2023
Background Femoral neck fractures represent a significant public health concern, particularly in the elderly population. A thorough understanding and assessment of these fractures are deemed essential for optimal treatment and management.

Mechanical Strain‐Programmed SDC1+ Sheath Fibroblasts Trigger CXCR4hi Neutrophil‐Mediated Enthesitis in Ankylosing Spondylitis

Advanced Science, EarlyView.
In ankylosing spondylitis (AS), mechanical strain‐programmed SDC1+ sheath fibroblasts secrete CXCL5 to recruit neutrophils and promote the activation of CXCR4hi neutrophils, thereby exacerbating enthesitis by promoting neutrophil extracellular traps (NETs) formation. SOX5 controls the generation of SDC1+ sheath fibroblasts via super‐enhancers.

Threading the Needle: Intrapelvic Displacement of a Femoral Neck Fracture through the Obturator Foramen

Case Reports in Orthopedics, 2018
Despite timely and appropriate management, displaced femoral neck fractures are often devastating injuries for the young patient. The risk of negative sequelae is further amplified with increasing displacement and vertical fracture patterns.

CGRP Enhances the Regeneration of Bone Defects by Regulating Bone Marrow Mesenchymal Stem Cells Through Promoting ANGPTL4 Secretion by Bone Blood Vessels

Advanced Science, EarlyView.
CGRP interacts with HMEC‐1 by binding to surface receptors, influencing the downstream FAK/AKT/VEGF signaling pathway, and promoting the secretion of ANGPTL4 from vascular endothelial cells into the bone microenvironment. This, in turn, regulates the differentiation of BMSCs into osteoblasts, thus promoting bone formation. ABSTRACT Bone angiogenesis is

Vascularity of femoral head and its assessment after femoral neck fractures

Journal of Orthopaedic Diseases and Traumatology, 2018
Femoral neck fracture has an annual incidence of 1 per 1000 population; in young patients, functional prognosis is not good due to risk of osteonecrosis. Femoral head vascularity is mostly contributed by retinacular vessels and lateral epiphyseal artery.

Use of Reconstruction Nails to Manage Ipsilateral Displaced Femoral Neck-Shaft Fractures: Assessment of a New Approach

Journal of Orthopaedic Surgery, 2002
Purpose. Owing to unpredictable femoral neck reduction, reconstruction nails are not suitable for fixation of group 3 ipsilateral femoral neck-shaft fractures. We developed a new one-step fixation technique to overcome this problem.
