Femoral head translation in borderline and definite dysplastic hips during weight‐bearing: 2D/3D image registration analysis

Journal of Experimental Orthopaedics, 2023
Purpose The aims of this study were to 1) assess femoral head translation during weight‐bearing in symptomatic developmental dysplasia of the hip (DDH) and 2) compare it between borderline DDH and definite DDH. Methods The study included four individuals

Analysis of Femoral Components of Cemented Total Hip- Arthroplasty [PDF]

arXiv, 2014
In cemented Total Hip Arthroplasty (THA), material chosen for femoral stem and cross section of stem itself, proved to be critical parameters for, stress distribution in the femoral components, interfacial stresses and micro movements. Titanium alloy (Ti6Al4V), when used as a material for femoral stem, recorded large displacement as compared to ...

Hydroxyapatite Binding Peptide Lipid Nanoparticles for Biomimetic mRNA Delivery to Bone

Advanced Therapeutics, EarlyView.
Targeted delivery of therapeutic mRNA to peripheral tissues, including bone, is currently challenging. In the current work, a hydroxyapatite binding peptide (HABP) is conjugated to mRNA lipid nanoparticles (LNPs). HABP‐LNPs delivered systemically are demonstrated to reduce transfection in the liver and improve transfection in the femurs of mice ...

Relationship between anterior or posterior femoral head necrosis and collapse based on MRI-defined key necrotic layer sets

Journal of Orthopaedic Surgery and Research
Background Current clinical studies on femoral head necrotic lesions primarily focus on the medial and lateral regions, while detailed MRI-based methods to evaluate the relationship between anterior or posterior necrosis and collapse remain lacking ...

A Rabbit Model of Avascular Necrosis of Femoral Head Using Surgical Trauma and Systemic Steroids

Bezmiâlem Science, 2020
Objective:Avascular necrosis of the femoral head (ANFH) is a disease caused by the diminished circulation of the femoral head. The incidence of the disease is increasing and it has heavy socioeconomical burden.

NETs‐CD44‐IL‐17A Feedback Loop Drives Th17‐Mediated Inflammation in Behçet's Uveitis

Advanced Science, EarlyView.
In experimental autoimmune uveitis (EAU), neutrophils interact with T helper 17 (Th17) cells through neutrophil extracellular traps (NETs) to exert a pro‐inflammatory effect. In vitro and in vivo experiments identify that NETs promote IL‐17A secretion in Th17 cells via CD44, and increasing IL‐17A further induces more NETs formation.

Osteonecrosis of the Femoral Head Caused by Bone Marrow Blockage: A Case Report

Journal of Orthopaedic Surgery, 2006
Interruption of the blood flow may occur in intraosseous arteries within the femoral head. We report a 72-year-old woman who developed osteonecrosis of the femoral head 11 months after surgery involving massive cementing of a segmental distal femoral ...

An Irreducible Hip Dislocation with Femoral Head Fracture [PDF]

Journal of Trauma and Injury, 2018
Urgent reduction is required in cases of traumatic hip dislocation to reduce the risk of avascular necrosis of the femoral head. However, in cases of femoral head fractures, the dislocated hip cannot be reduced easily, and in some cases, it can even be ...

Shared and Unique Neural Codes for Biological Motion Perception in Humans and Macaque Monkeys

Advanced Science, EarlyView.
Cross‐species fMRI studies reveal distinct neural mechanisms for biological motion (BM) processing. In humans, the posterior superior temporal sulcus (hpSTS) selectively responds to conspecific BM, while monkeys process BM from both species in the middle temporal area (MT).

Unique bone microanatomy reveals ancestry of subterranean specializations in mammals

Evolution Letters, Volume 6, Issue 6, Page 552-561, December 2022., 2022
Abstract Acquiring a subterranean lifestyle entails a substantial shift for many aspects of terrestrial vertebrates’ biology. Although this lifestyle is associated with multiple instances of convergent evolution, the relative success of some subterranean lineages largely remains unexplained.
