In all cases, failure was due to imminent fracture of the prosthesis across the pivot of the central hinge section. This result is in contrast with previous in-vitro and in-vivo experience with single-piece silicone Swanson and Sutter metacarpophalangeal prostheses, which both tend to fracture at the junction of the distal stem and the hinge. In comparison with earlier in-vitro simulator tests of the Sutter metacarpophalangeal prosthesis, the NeuFlex prostheses showed a greater longevity before fracture. To date, no other reports of fracture of the NeuFlex metacarpophalangeal prosthesis have been reported, either in vitro or in vivo.<\/jats:p>","DOI":"10.1243\/095441105x9192","type":"journal-article","created":{"date-parts":[[2005,3,14]],"date-time":"2005-03-14T22:38:17Z","timestamp":1110839897000},"page":"105-110","source":"Crossref","is-referenced-by-count":21,"title":["NeuFlex metacarpophalangeal prostheses tested in vitro"],"prefix":"10.1177","volume":"219","author":[{"given":"T J","family":"Joyce","sequence":"first","affiliation":[{"name":"National University of Ireland Department of Mechanical and Biomedical Engineering Galway, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Unsworth","sequence":"additional","affiliation":[{"name":"University of Durham School of Engineering Durham, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2005,2,1]]},"reference":[{"key":"bibr1-095441105X9192","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197254030-00001"},{"key":"bibr2-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-7681(98)80004-1"},{"key":"bibr3-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681(93)90203-R"},{"key":"bibr4-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1054\/jhsb.2000.0402"},{"key":"bibr5-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681(84)90047-0"},{"key":"bibr6-095441105X9192","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668020-00005"},{"key":"bibr7-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1136\/ard.37.3.255"},{"key":"bibr8-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199709000-00005"},{"key":"bibr9-095441105X9192","doi-asserted-by":"publisher","DOI":"10.3109\/02844319609056397"},{"key":"bibr10-095441105X9192","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(96)80197-3"},{"key":"bibr11-095441105X9192","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200310000-00001"},{"key":"bibr12-095441105X9192","volume":"27","author":"Delaney R.","year":"2002","journal-title":"J.
