Finite element analysis of the equivalent stress distribution in Schanz screws during the use of a femoral fracture distractor

Revista Brasileira de Ortopedia
To evaluate the mechanical stress and elastic deformation exercised in the thread/shaft transition of Schanz screws in assemblies with different screw anchorage distances in the entrance to the bone cortex, through the distribution and location of ...

A new mini-navigation tool allows accurate component placement during anterior total hip arthroplasty. [PDF]

, 2018
Introduction: Computer-assisted navigation systems have been explored in total hip arthroplasty (THA) to improve component positioning. While these systems traditionally rely on anterior pelvic plane registration, variances in soft tissue thickness ...

Soft Robotic Sim2Real via Conditional Flow Matching

Advanced Intelligent Systems, EarlyView.
A new framework based on conditional flow matching addresses the persistent Sim2Real gap in soft robotics. By learning a conditional probability path, the model directly transforms inaccurate simulation data to match physical reality, successfully capturing complex phenomena like hysteresis.

circNR3C2 promotes chondrogenic differentiation and cartilage repair of human adipose‐derived stem cells via the hsa‐miR‐647/SOX9 pathway

Animal Models and Experimental Medicine, EarlyView.
The hypothesis diagram illustrates the function and mechanism of circNR3C2: circNR3C2 overexpression can up‐regulate COL2, Aggrecan and SOX9 expression, and regulate chondrogenic differentiation of hADSCs by targeting hsa‐miR‐647. Abstract Background Human adipose‐derived stem cells (hADSCs) are seed cells with application prospects in cartilage repair.

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Effect of Heating Temperature on Wear Rate, Tensile Strength, and Crystallinity of Cantula Fiber-Reinforced Magnesium/Hydroxyapatite/ Shellac for Bone Screw Material

Mekanika
Bone screws are screws for bone that are joined to support plates. Bone screws generally use metal as the primary material because of its high mechanical properties, such as stainless steel and titanium.
