Six retrospective cases of pelvic bone tumors were segmented. Three different users (trained engineer (TE), orthopedic student (OS), expert orthopedic surgeon (OE)) performed multimodal semi-automatic segmentation on registered CT and MRI sequences. Inter-user variability was evaluated on the tumor models using the symmetrical Hausdorff distances and the DICE similarity coefficient. The mean symmetrical Hausdorff distance was 1.1 mm between TE and OS, 3.8 mm between TE and OE, and 3.6 mm between OS and OE. The mean values for the DICE similarity coefficient were 0.91 between TE and OS, 0.79 between TE and OE, and 0.82 between OS and OE. In patient 5, the DICE coefficient between TE and OE, and OS and OE dropped to 0.18 and 0.24 respectively. This study suggests that the inter-user variability between two segmentations of the same tumor cannot be overlooked, especially in complex pelvic tumors: OE expertise seems mandatory for tumor segmentation validation.

This study seeks to present the design process of a surgical practice rig designed to support care for the ruptured SLIL. The novelty of this practice rig is apparent, because it explores multiple 3D printing technologies in order to evaluate which is the most suitable for a medical practice rig of this nature. User feedback indicated that hybrid manufacturing applications utilising traditional fabrication techniques and 3D printing technologies was superior when accounting for the requisite movement capabilities and modularity the rig needed to process. Throughout the design process, a user-centred approach was used to translate the needs of the surgeon into a functional product. An emergent design methodology was used to incorporate feedback from medical professionals and engineers. These two methodological approaches were used to ensure the end-product fulfilled several functions: aiding surgeons to understand a new surgical implant, providing reasonable bio-fidelity in wrist function to enable surgical practice, and remaining simple enough to be understood by a patient undergoing a complex procedure. Following user tests with a variety of hand and wrist surgeons, we found this rig suitable for several applications. The rig functioned as expected, providing surgeons with a means to experiment with a new surgical implant, and proved an effective tool for patient education.</p></div>","PeriodicalId":72210,"journal":{"name":"Annals of 3D printed medicine","volume":"9 ","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47400108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various designs and materials used for the tip have led to a wide range of applications. In this review, we discuss the characteristics of essential tip materials such as rayon, polyester, nylon, and polyurethane in the context of specimen collection from various substrates. Further, this article reviews swab manufacturing techniques, including injection molding and calendar roll pressing, among others. In recent years, advances in additive manufacturing technology have made it possible to produce swabs in a fast and efficient manner. Furthermore, the design for additive manufacturing (DfAM) is given for the production of swabs. We also examine how 3-D printing of bio-resin swabs has revolutionized the manufacturing process, making it autonomous, quicker, more efficient, and environmentally friendly. Additionally, a shortage of medical devices for testing the SARS-2 virus has zealously motivated the medical industry to revolutionize through additive manufacturing of swabs, thus revolutionizing the medical industry.
