The NeuFlex\u00ae implant was introduced to improve on the clinical performance of other silicone implants by having a pre-flexed hinge. By visually examining a cohort of 30 explanted NeuFlex\u00ae metacarpophalangeal joint prostheses we sought to identify the failure modes of these implants. Seven were not fractured, 11 had fractured across the hinge, nine had fractured at the junction of the distal stem and the hinge, and three showed fractures at both the hinge and at the junction of the distal stem and the hinge. These data may prove helpful in identifying how the performance of single-piece silicone implant designs can be improved.<\/jats:p>","DOI":"10.1177\/1753193418774500","type":"journal-article","created":{"date-parts":[[2018,5,13]],"date-time":"2018-05-13T00:03:58Z","timestamp":1526169838000},"page":"1083-1087","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Sites of fractures in explanted NeuFlex\u00ae silicone metacarpophalangeal joint prostheses"],"prefix":"10.1177","volume":"43","author":[{"given":"Thomas J.","family":"Joyce","sequence":"first","affiliation":[{"name":"School of Engineering, Newcastle University, Newcastle upon Tyne, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grey","family":"Giddins","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Royal United Hospital, Bath, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,5,12]]},"reference":[{"key":"bibr1-1753193418774500","unstructured":"ASTM-F1781-15.
