“…A limitation of this biomechanical study was the low number of specimens, but this has similarly been reported in other comparable studies [ 22 , 23 , 24 , 25 ]. One explanation for the low number of specimens is certainly the availability of body donors, which is limited.…”

“…During the biomechanical tests, the movements of the distal fibula and tibia were recorded using an optical 3D measurement system that tracks two marker plates (kolibri CORDLESS, Fraunhofer IOF, Jena, Germany; measurement uncertainty of 20–100 µm) [ 24 ]. Each marker plate consisted of three passive, spherical markers 6.5 mm in diameter attached to a jet-black plate with a 2.5 cm diameter.…”

In the treatment of ankle fractures, complications such as wound healing problems following open reduction and internal fixation are a major problem. An innovative alternative to this procedure offers a more minimally invasive nail stabilization. The purpose of this biomechanical study was to clarify whether this method was biomechanically comparable to the established method. First, the stability (range of motion, diastasis) and rotational stiffness of the native upper ankle were evaluated in eight pairs of native geriatric specimens. Subsequently, an unstable ankle fracture was created and fixed with a locking plate or a nail in a pairwise manner. The ankles showed significantly less stability and rotational stiffness properties after nail and plate fixations than the corresponding native ankles (p < 0.001 for all parameters). When comparing the two methods, both showed no differences in their range of motion (p = 0.694) and diastasis (p = 0.166). The nail also presented significantly greater rotational stiffness compared to the plate (p = 0.001). However, both fixations remained behind the native stability and rotational stiffness. Due to the comparable biomechanical properties of the nail and plate fixations, an early weight-bearing following nail fixation should be assessed on a case-by-case basis considering the severity of fractures.

“…The application of digitalisation and 3D documenting techniques provides important information for the restoration, conservation and recovery of cultural heritage. They are also among the main tools to improve their knowledge and dissemination [7,33]. In the case of the baptismal font of the church of Santiago Apóstol in Montilla, photogrammetric techniques based on Structured from Motion were used to digitally document the piece due to its size.…”

Historical-graphical analysis and digital preservation of cultural heritage: case study of the baptismal font of the church of Santiago Apóstol in Montilla (Córdoba, Spain)

Stone is a characteristic element in the construction of buildings and monuments in the Middle Ages in Spain. This is so mainly due to its durability and, in baptismal fonts, specifically, its symbolism: Jesus Christ is the cornerstone, he comes to save us and is the foundation of the life of the Christian and of the Universal Church. The application of virtual 3D reconstruction is essential in the conservation of this type of heritage, together with scientific techniques and methods, and the analysis of historical-graphic documentation. Focusing on these three aspects, the baptismal font of the church of Santiago Apóstol de Montilla will be taken as a reference. The baptismal font of the church of Santiago Apóstol in Montilla (Córdoba, Spain), whose exact origin is unknown, is one of the most important heritage assets. San Francisco Solano, known as the “Thaumaturge of the New World”, was baptised in it. For over four centuries, the temple has been the Main Church of the head of the Marquisate of Priego. This study aims to know, document and carry out a digital reconstruction of an important piece of the monumental heritage of the Catholic Church: the baptismal font of the church of Santiago Apóstol in Montilla. To this end, we searched a major literature review focused on the use of photogrammetry for reading old graphics and deciphering texts. After that we analysed the graphic documentation derived from the restoration process conducted by Cordovan restorer Vázquez Arjona in the late twentieth century. The application of 3D digitisation and documentation techniques has allowed not only to analyse this important heritage element in detail through a virtual reconstruction, but also to make a far-reaching discovery regarding one of its elements, the unknown inserted inscription in the baptismal font band.

“…Thus, in the field of studying architectural heritage, the integration of information from multiple sensors is also studied, combining metric data with temperatures and the creation of a 3D thermal texture [ 18 , 19 ]. Or the analysis of the texture of the color and 3D shape [ 20 ], and the changes in the deformations of the Badillo et al [ 21 ] paintings. Most of the studies dealing with small archeological objects focus on 3D implementation.…”

Reverse engineering and the creation of digital twins are advantageous for documenting, cataloging, and maintenance control tracking in the cultural heritage field. Digital copies of the objects into Building Information Models (BIM) add cultural interest to every artistic work. Low-cost 3D sensors, particularly structured-light scanners, have evolved towards multiple uses in the entertainment market but also as data acquisition and processing techniques for research purposes. Nowadays, with the development of structured-light data capture technologies, the geometry of objects can be recorded in high-resolution 3D datasets at a very low cost. On this basis, this research addresses a small artifact with geometric singularities that is representative of small museum objects. For this, the precision of two structured-light scanners is compared with that of the photogrammetric technique based on short-range image capture: a high-cost Artec Spider 3D scanner, and the low-cost Revopoint POP 3D scanner. Data capture accuracy is evaluated through a mathematical algorithm and point set segmentation to verify the spatial resolution. In addition, the precision of the 3D model is studied through a vector analysis in a BIM environment, an unprecedented analysis until now. The work evaluates the accuracy of the devices through algorithms and the study of point density at the submillimeter scale. Although the results of the 3D geometry may vary in a morphometric analysis depending on the device records, the results demonstrate similar accuracies in that submillimeter range. Photogrammetry achieved an accuracy of 0.70 mm versus the Artec Spider and 0.57 mm against the Revopoint POP 3D scanner.
