Our specific aims were to develop a model of PSAB, adapted to fracture care, to evaluate if this brace would be well tolerated by healthy volunteers and to determine its mechanical properties as compared with conventional methods of wrist immobilization.<\/jats:p><jats:p>\n          Materials and Methods\u2003Several three-dimensional-printed splint prototypes were designed by mechanical engineers based on surgeons' and hand therapists' clinical expertise. These experimental braces underwent testing in a preclinical study involving 10 healthy volunteers, assessing comfort, satisfaction, and activities. The final prototype was mechanically compared with a conventional cast and a prefabricated splint, testing different closing systems. A mathematical algorithm was created to automatically adapt the final PSAB model to the patient's anatomy.<\/jats:p><jats:p>\n          Results\u2003The final prototype achieved an overall satisfaction score of 79%, weighing less than 90\u2009g, made from polyamide, and fixed using hook and loop straps. The PSAB stiffness varied between 0.64 and 0.99 Nm\/degree, surpassing the performance of both conventional plaster casts and prefabricated splints.<\/jats:p><jats:p>\n          Conclusion\u2003The final wrist PSAB model, adapted for fracture treatment, is lightweight, comfortable, and provides anatomical contention. It is currently being tested for the treatment of stable distal radius and scaphoid fractures in comparison to conventional plaster cast.<\/jats:p>","DOI":"10.1055\/s-0044-1779053","type":"journal-article","created":{"date-parts":[[2024,2,2]],"date-time":"2024-02-02T23:49:42Z","timestamp":1706917782000},"page":"390-397","source":"Crossref","is-referenced-by-count":7,"title":["Developing 3D-Printed Wrist Splints for Distal Radius and Scaphoid Fractures"],"prefix":"10.1055","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5426-1762","authenticated-orcid":false,"given":"Bernadette","family":"Tobler-Ammann","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic, Plastic and Hand Surgery, Inselspital Bern, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fr\u00e9d\u00e9ric","family":"Schuind","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Surgery, Universit\u00e9 Libre de Bruxelles, Brussels, Belgium"},{"name":"Swibrace Ltd, Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lo\u00efc","family":"Voillat","sequence":"additional","affiliation":[{"name":"Swibrace Ltd, Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1902-6230","authenticated-orcid":false,"given":"Th\u00e9ophile","family":"Gentilhomme","sequence":"additional","affiliation":[{"name":"R&D Department, Idiap Research Institute, Martigny, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2491-3985","authenticated-orcid":false,"given":"Esther","family":"V\u00f6gelin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic, Plastic and Hand Surgery, Inselspital Bern, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"No\u00e9","family":"Murith","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, HES-SO University of Applied Sciences, Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1821-0618","authenticated-orcid":false,"given":"Bernard","family":"Masserey","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, HES-SO University of Applied Sciences, Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2024,2,2]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1097\/01.bot.0000199121.84100.fb","article-title":"A randomized, controlled trial of distal radius fractures with metaphyseal displacement but without joint incongruity: closed reduction and casting versus closed reduction, spanning external fixation, and optional percutaneous K-wires","volume":"20","author":"H J Kreder","year":"2006","journal-title":"J Orthop Trauma"},{"issue":"07","key":"ref2","doi-asserted-by":"crossref","first-page":"1280","DOI":"10.1016\/j.jhsa.2014.04.018","article-title":"Complications associated with operative versus nonsurgical treatment of distal radius fractures in patients aged 65 years and older","volume":"39","author":"K Lutz","year":"2014","journal-title":"J Hand Surg Am"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"404","DOI":"10.1302\/0301-620X.78B3.0780404","article-title":"Redisplaced unstable fractures of the distal radius: a prospective randomised comparison of four methods of treatment","volume":"78","author":"M M McQueen","year":"1996","journal-title":"J Bone Joint Surg Br"},{"issue":"04","key":"ref4","doi-asserted-by":"crossref","first-page":"290","DOI":"10.1197\/j.jht.2007.06.001","article-title":"Patient-perceived outcome after displaced distal radius fractures.
