It is unclear to what extent custom orthoses versus traditional off the shelf variants are currently provided to treat mallet injury. The study aims to investigate current practice regarding the conservative treatment of mallet injury in Ireland.

Healthcare professionals involved in the treatment of mallet injuries from both public and private settings were eligible for inclusion. Data collection involved convenience and snowball sampling with the survey being promoted by professional bodies, distributed at national meetings and circulated via social media.

Non personalised orthosis including the Stack splint were most frequently applied (58 %). Regarding 3D printing, 52 % of participants reported they were not aware of 3DP in healthcare. However, 80 % overall said they would be interested in using it in the future. The inference from this is that they have a positive attitude toward the use of 3D printing, considering they have a low knowledge of using it in this discipline.</div></div><div><h3>Originality/value</h3><div>This study provides an insight into healthcare professionals’ recent experiences of treating mallet injuries in the Irish healthcare system. There remains a lack of custom orthosis creation to treat mallet injury. The respondent's openness to using 3D printing technology is promising and suggests that in the future 3D printing of custom orthoses may have a role in the treatment of mallet injuries. However, custom care, and not just a custom orthosis, would provide patients with optimal treatment.</div></div>","PeriodicalId":72210,"journal":{"name":"Annals of 3D printed medicine","volume":"17 ","pages":"Article 100184"},"PeriodicalIF":0.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapidly increasing demand for reconstruction and restoration of highly intricate and responsive bone implants has encouraged bone tissue engineering to yield implants that substitute the native bone, both physically and biologically. As this technology is still in its infancy, different limitations can be encountered, such as the lack of in-depth characterization of scaffolds and limited visualization of a general framework, which can be overcome with further explorative studies. With computerized bio-fabrication, 3D printing aims to perfectly adapt implants, individually analyzing data at the level of cells, tissues, organs, and organic systems, ending this entire process under pre-bioprinting. The locus and susceptibility to bare load are primary considerations in selecting among widely available biomaterial options and printing techniques, including bio-ceramics, metals, bioinks, selective laser melting, directed energy deposition (laser or e-beam), and drop-on-powder printing. The addition of growth factors and mesenchymal stem cells allows the maintenance of the balance between osteoclasts and osteoblasts, the cartilage tissue formation, and contributes to the overall bone remodeling and regeneration processes.

In the context of hemodynamic studies, computational fluid dynamics emerges as a highly innovative and promising approach. We propose to augment these computational studies with cell-based experiments in individualized artery geometries using personalized scaffolds and vascular cell experiments. Previous research has demonstrated that the development of Sickle Cell Disease (SCD)-Related Vasculopathy is dependent on personal geometries and flow characteristics of the carotid artery. This fact leaves conventional animal experiments unsuitable for gaining patient-specific insights into cellular signaling, as they cannot replicate the personalized geometry. These personalized dynamics of cellular signaling may further impact disease progression, yet remains unclear. This paper presents a six-step methodology for creating personalized large artery scaffolds, focusing on high-precision models that yield biologically interpretable patient-specific results. The methodology outlines the creation of personalized large artery models via Additive Manufacturing suitably for supporting cell culture and other cellular experiments. Additionally, it discusses how different Computer-Aided-Design (CAD) construction modes can be used to obtain high-precision personalized models, while simplifying model reconfigurations and facilitating adjustments to general designs such as system connections to bioreactors, fluidic systems and visualization tools. A proposal for quality control measures to ensure geometric congruence for biological relevance of the results is added.
