Plantar pressure distribution is a thoroughly recognized parameter for evaluating foot structure and biomechanical behavior, as it is utilized to determine musculoskeletal conditions and diagnose foot abnormalities. Experimental testing is currently being utilized to investigate static foot conditions using invasive and noninvasive techniques. These methods are usually expensive and laborious, and they lack valuable data since they only evaluate compressive forces, missing the complex stress combinations the foot undergoes while standing. The present investigation applied medical and engineering methods to predict pressure points in a healthy foot soft tissue during normal standing conditions. Thus, a well-defined three-dimensional foot biomodel was constructed to be numerically analyzed through medical imaging. Two study cases were developed through a structural finite element analysis. The first study was developed to evaluate barefoot behavior deformation and stresses occurring in the plantar region. The results from this analysis were validated through baropodometric testing. Subsequently, a customized 3D model total-contact foot orthosis was designed to redistribute peak pressures appropriately, relieving the plantar region from excessive stress. The results in the first study case successfully demonstrated the prediction of the foot sole regions more prone to suffer a pressure concentration since the values are in good agreement with experimental testing. Employing a customized insole proved to be highly advantageous in fulfilling its primary function, reducing peak pressure points substantially. The main aim of this paper was to provide more precise insights into the biomechanical behavior of foot pressure points through engineering methods oriented towards innovative assessment for absolute customization for orthotic devices.

“…We strongly believe that 3D technologies can improve early diagnosis of subungual glomus tumor recurrence, demonstrate the relationship with the adjacent bone and vessels and allow the identification of the exact tumor location by measuring its distance to proximal, medial and lateral nail folds, although it is still a new technology and has limited access at the moment. Indeed, other applications of 3D technologies are also possible, such as 3D biomodel printing on an original size and the use of virtual reality and navigation that may also contribute to preoperative diagnosis, improving surgical management 3 …”

“…However, power Doppler high‐frequency ultrasonography is a complex technique and presents limited detection ability for small tumor recurrences, that may be entirely missed or difficult to localize. We describe the use of biomodelling and 3D technologies that allows the detection of tumoral recurrences more easily, as well as providing supplementary information for the radiologist report, such as select anatomical structure analysis, images with 360° rotation and visualization in transparency mode for detailed anatomic analysis 3 . We performed magnetic resonance imaging using surface‐coil and 3D isotropic sequences for image acquisition in a subungual glomus tumor, followed by lesion segmentation using the 3D Slicer software, version 4.11.10 (Birmingham, UK).…”

Using the magnetic resonance imaging, we were able to obtain a solid nodule hyperintense on fat-suppressed T2-weighted an hypointense on T1 weighted image, located in the nail bed, with bone remodelling of the adjacent distal phalanx and intense contrast enhancement, demonstrating the vascular origin of the tumor (Figure 1).…”

Preoperative evaluation of a 41-year-old female with a subungual glomus tumor. Magnetic resonance imaging (MRI) using surface-coil on a sagittal T2-fat saturation sequence showing the subungual glomus tumor (open arrow). Note that on MRI it is difficult to visualize the digital artery and the distance between the tumor and the nail folds. Segmentation of MRI images using 3D Slicer software in the coronal and sagittal plans provides the distances from the tumor (in green), nail folds and the digital arteries with greatest calibre (in red). 3D biomodel printing on an original size also allows the assessment of the relationship between the tumor, nail folds and the bone (in white).

Introduction: 3D biomodels represent a cutting-edge advancement in medical imaging technology. The incorporation of 3D technologies in dermatology through the acquisition of onychological images, 3D reconstruction, and development of customized equipment to assist in surgeries demonstrated reduction in operating times and improved surgical outcomes. Additionally, the use of 3D printing in surgical simulation provided a safe environment for training and education. This article explores the application of 3D biomodels in dermatology, focusing on three clinical cases involving nail tumors. Case Presentation: In case 1, a glomus tumor was visualized in 3D, guiding the creation of a personalized surgical device. The minimally invasive surgery, facilitated by the biomodel, resulted in successful tumor removal. Case 2, featuring a subungual keratoacanthoma, utilized 3D biomodels for conservative surgery planning, anatomical comprehension, and patient communication. Case 3 involved a longitudinal groove, where biomodels aided in precise lesion localization and surgical planning. Conclusion: The integration of virtual and physical anatomical biomodels proves valuable in surgical dermatology, contributing to enhanced treatment quality, patient safety, and medical education.
