Comparative Evaluation of Neural Networks and Transfer Learning for Predicting Mechanical Properties of 3D‐Printed Bone Scaffolds

Macromolecular Materials and Engineering, EarlyView.
This study compares Convolutional Neural Networks (CNNs) and Transfer Learning (TL) for predicting key mechanical properties (volume fraction, Poisson's ratio, and elastic modulus) of 3D‐printed bone scaffolds. Using image‐based inputs derived from Body Centred Cubic lattice structures, CNNs outperformed ResNet‐based TL models in accuracy. The proposed

StraightTrack: Towards Mixed Reality Navigation System for Percutaneous K-wire Insertion [PDF]

arXiv
In percutaneous pelvic trauma surgery, accurate placement of Kirschner wires (K-wires) is crucial to ensure effective fracture fixation and avoid complications due to breaching the cortical bone along an unsuitable trajectory. Surgical navigation via mixed reality (MR) can help achieve precise wire placement in a low-profile form factor.
