Probabilistic finite element analysis of the uncemented hip replacement-effect of femur characteristics and implant design geometry [PDF]

, 2010
In the present study, a probabilistic finite element tool was assessed using an uncemented total hip replacement model. Fully bonded and frictional interfaces were investigated for combinations of three proximal femurs and two implant designs, the ...

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, Volume 13, Issue 51, 14 September 2026.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

Engineered Exosomal miR‐146a‐5p Reprograms BMSC Fate and Restores Mitochondrial Homeostasis in Glucocorticoid‐Induced Osteonecrosis of Femoral Head

Advanced Science, Volume 13, Issue 49, 3 September 2026.
Exosomal miR‐146a‐5p is identified as a pivotal regulator in steroid‐induced osteonecrosis. Its reduction activates NF‐κB signaling, compromises mitophagy, and disrupts mitochondrial bioenergetics, resulting in autophagic disequilibrium. Engineered exosomes delivering miR‐146a‐5p reinstate mitochondrial function, augment oxidative phosphorylation and ...

A new measurement method for the radiographic assessment of the proximal femur: the centertrochanter distance

Acta Orthopaedica et Traumatologica Turcica, 2020
Objectives: We developed a new method -measuring the perpendicular distance between the center of the femur head and the tip of the trochanter- for radiographic assessment of the proximal femur.\nMethods: The “center-trochanter distance” (CTD) refers to ...
