“…The biological response to the host bone, on the other hand, is usually achieved by monolithic or surface modification of such implants [ 9 ]. In just the past few years, metal 3D printing technology in the medical field, especially the application of orthopedics has been highly valued, and its innovative potential and application prospects are more generally favored [ 50 , 108 , [184] , [185] , [186] , [187] , [188] ]. Several metal 3D printing orthopedic implant applications are shown in Fig.…”

“…Therefore, talus implant treatment is a suitable way to relieve pain while preserving the functional range of motion so patients will have less pain and better function during activity 5,6 . Custom total talus replacement, which involves designing a prosthesis component with tailored dimensions, is a viable alternative [7][8][9] . Nevertheless, quantifying variations of the talus is fundamental before talus implant design.…”
Fractures of the talar neck and body are associated with spine fractures and scoliosis deformity, which affect cosmetic appearance and cause difficulty in ambulation. The implant design for talus surgery is thriving as a functional alternative in case of severe talar destruction, focusing on segmentation and reconstruction of the talus's shape. However, manual segmentation of the talus is time-consuming and subjective. In this study, we exploited the automatic segmentation framework to efficiently train a deep learning-based model to accurately segment the talus based on computed tomography imaging. We developed three model configurations with nnU-Net and investigated their Dice similarity coefficients (DSC) and 95% Hausdorff distances (HD95) for talus segmentation on a CT image dataset. The three configurations performed well (DSC>0.95, HD95<0.6). When tested on the same samples, one of the configurations was more efficient while ensuring higher accuracy. We propose to focus on talus anatomic variations with increasing age based on this framework and apply it to clinical trials at the next stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
