This device incorporates loops of polyester braid which are secured by a crimped titanium sleeve. In tensile tests, all loops failed, by slippage through the crimped sleeve, at 434 \u00b1 15 N (mean \u00b1 standard deviation from five loops) for a single crimp and 415 \u00b1 15 N (from five loops) for two crimps. The intact system was then tested according to the ASTM standard. In a static test, all five specimens failed by slippage of the braid through the sleeve. Initial slippage occurred between 600 and 700 N, but the mean maximum load sustained was 1090 \u00b1 140 N. Dynamic tests were performed on ten constructs at a frequency of 5 Hz, under a range of loading conditions. The maximum load applied in any of the tests was 825 N. Two constructs did not complete the required 5 \u00d7 10\n                    <jats:sup>6<\/jats:sup>\n                    test cycles because of fracture of their spinous process hooks. However, other tests, under the same conditions, showed no signs of failure. Fracture occurred as a result of fretting damage from the recommended stainless steel roll pins.\n                  <\/jats:p>","DOI":"10.1243\/0954411001535516","type":"journal-article","created":{"date-parts":[[2002,10,1]],"date-time":"2002-10-01T19:24:52Z","timestamp":1033500292000},"page":"489-495","source":"Crossref","is-referenced-by-count":5,"title":["Mechanical testing of a flexible fixation device for the lumbar spine"],"prefix":"10.1177","volume":"214","author":[{"given":"J C","family":"Leahy","sequence":"first","affiliation":[{"name":"University of Aberdeen Department of Bio-Medical Physics and Bio-Engineering Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K J","family":"Mathias","sequence":"additional","affiliation":[{"name":"University of Aberdeen Department of Bio-Medical Physics and Bio-Engineering Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D W L","family":"Hukins","sequence":"additional","affiliation":[{"name":"University of Aberdeen Department of Bio-Medical Physics and Bio-Engineering Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D E T","family":"Shepherd","sequence":"additional","affiliation":[{"name":"University of Aberdeen Department of Bio-Medical Physics and Bio-Engineering Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W F","family":"Deans","sequence":"additional","affiliation":[{"name":"University of Aberdeen Department of Engineering Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2000,5,1]]},"reference":[{"key":"bibr1-0954411001535516","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199701150-00005"},{"key":"bibr2-0954411001535516","doi-asserted-by":"publisher","DOI":"10.1243\/0954411001535507"},{"key":"bibr3-0954411001535516","volume-title":"BS 7252: Part 3: 1997 Metallic Material for Surgical Implants.
