We measured the Disability of the Arm, Shoulder, and Hand (DASH) and Short Form 36 (SF-36) scores at a mean of 20 months. Pain severity was assessed using a visual analogue scale (VAS), and level of patient satisfaction was assessed using a 5-point scale. The mean DASH scores at follow up were 27 for those that had a trapeziectomy and 35 for those that had a Pi2 arthroplasty ( p = 0.001). There was no difference in the VAS for pain, SF-36 scores, or other parameters assessed. Six out of 18 (33%) thumbs in the Pi2 group had multiple operations, usually for dislocation or subluxation of the implant. The early results of Pi2 arthroplasty show a high complication rate compared with trapeziectomy and no identifiable benefit.<\/jats:p>","DOI":"10.1177\/1753193411433176","type":"journal-article","created":{"date-parts":[[2012,1,6]],"date-time":"2012-01-06T05:14:17Z","timestamp":1325826857000},"page":"617-620","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":57,"title":["Thumb carpometacarpal osteoarthritis: trapeziectomy versus pyrocarbon interposition implant (Pi2) arthroplasty"],"prefix":"10.1177","volume":"37","author":[{"given":"M.","family":"Maru","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Trauma, Sunderland Royal Hospital, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Jettoo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Trauma, Sunderland Royal Hospital, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Tourret","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Trauma, Sunderland Royal Hospital, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Trauma, Sunderland Royal Hospital, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Irwin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Trauma, Sunderland Royal Hospital, Sunderland, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,1,5]]},"reference":[{"key":"bibr1-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2008.10.017"},{"key":"bibr2-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2006.05.009"},{"key":"bibr3-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1016\/S0072-968X(79)80007-8"},{"key":"bibr4-1753193411433176","first-page":"455","volume":"3","author":"Eaton RG","year":"1987","journal-title":"Clin"},{"key":"bibr5-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0274(199606)29:6<602::AID-AJIM4>3.0.CO;2-L"},{"key":"bibr6-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2007.02.025"},{"key":"bibr7-1753193411433176","doi-asserted-by":"crossref","first-page":"148","DOI":"10.1016\/j.main.2005.04.010","volume":"24","author":"Peguignot JP","year":"2005","journal-title":"Chir Main"},{"key":"bibr8-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199709000-00009"},{"key":"bibr9-1753193411433176","first-page":"CD004631","volume":"4","author":"Wajon A","year":"2005","journal-title":"Cochrane Database Syst Rev"},{"key":"bibr10-1753193411433176","doi-asserted-by":"publisher","DOI":"10.1097\/00005650-199206000-00002"}],"container-title":["Journal of Hand Surgery (European Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1753193411433176","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1753193411433176","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1753193411433176","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T22:48:33Z","timestamp":1777502913000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1753193411433176"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,1,5]]},"references-count":10,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2012,9]]}},"alternative-id":["10.1177\/1753193411433176"],"URL":"https:\/\/doi.org\/10.1177\/1753193411433176","relation":{},"ISSN":["1753-1934","2043-6289"],"issn-type":[{"value":"1753-1934","type":"print"},{"value":"2043-6289","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,1,5]]}}}
