“…The translation from an anatomically precise 3D surface model to a biomechanically FEA model presents its own set of challenges. First, we tapped into the capabilities of Geomagic Studio 11 [ 20 ], which played a pivotal role in the transformation of our STL surface model into a comprehensive 3D volumetric representation. Relying on the intricacies of the STL file's faceted data, we constructed an STP format volumetric model, ensuring that every nook and crevice of the anatomical geometry was reproduced.…”

Background Posterior malleolus fractures are known to be associated with ankle instability. The complexities involved in obtaining precise laboratory-based spatial pressure measurements of the ankle highlight the significance of exploring the biomechanical implications of these fractures. Methods Finite element analysis was utilized to examine the stress distribution across the contact surface of the ankle joint, both in its natural state and under varied sagittal fracture line angles. The study aimed to identify stress concentration zones and understand the influence of sagittal angles on stress distribution. Results Three distinct stress concentration zones were identified on the ankle's contact surface: the anterolateral tibia, the anteromedial tibia, and the fracture line. The most significant stress was observed at the fracture line when a fracture occurs. Stress at the fracture line notably spikes as the sagittal angle decreases, which can potentially compromise ankle stability. Larger sagittal angles exhibited only minor stress variations at the contact surface's three vertices. It was inferred that sagittal angles below 60° might pose risks to ankle stability. Conclusions The research underscores the potential implications of fractures on the stress profile of the ankle joint, emphasizing the role of the contact surface in ensuring stability. The identification of three zones of stress concentration and the influence of sagittal angles on stress distribution offers a valuable reference for therapeutic decision-making. Further, the study reinforces the importance of evaluating sagittal fracture angles, suggesting that angles below 60° may compromise ankle stability.

“…5 (c) and (d) show undesired holes in the recovered panoramic 3D result by PMA. Although the use of post-processing algorithms can fill these holes and obtain a complete panoramic 3D shape, the complex textures or details cannot be repaired [8]. In contrast, our OMA can achieve non-destructive panoramic 3D shape measurement.…”

Panoramic 3D measurement becomes increasingly important for fringe projection profilometry (FPP). Traditional physical markers-assisted (PMA) method suffers from inefficiencies and non-complete measurement. An optical markers-assisted (OMA) panoramic 3D method has been recently proposed, which enables accurate, efficient and non-destructive panoramic 3D measurement. In this paper, we give a comprehensive comparison between OMA and PMA, which provides reasonable suggestions for different panoramic 3D measurement applications.
