The Pyrocardan implant yields striking results but only few series exist, making the evidence scarce.<\/jats:p><jats:p>\n          Purpose\u2003The aim of this study was to conduct a prospective series using the Pyrocardan implant.<\/jats:p><jats:p>\n          Methods\u2003We compared the outcomes to a matched historical control group of patients operated on with ligament reconstruction and tendon interposition. The hypothesis was that the Pyrocardan implant would yield better patient-reported outcomes as well as the procedure would be safe and effective in relieving symptoms of CMC-1 osteoarthritis. In total, 30 patients were included in the prospective series. These 30 patients were compared, in a 1:3 design, to a matched historical group.<\/jats:p><jats:p>\n          Results\u2003Results were promising with visual analogue scale scores of 0.7 (rest) and 2.1 (function), key-pinch score of 5.1\u2009kg, and shortened Disability of the Arm, Shoulder, and Hand score of 14.3 after 1 year when using the Pyrocardan implant. The revision rate was 10%. We found no evidence of subsidence of the thumb. We found no differences in patient-reported outcomes between the two groups.<\/jats:p><jats:p>\n          Conclusions\u2003In conclusion, the Pyrocardan implant is a viable option in the treatment of CMC-1 osteoarthritis but with a significant revision rate. When comparing the Pyrocardan implant to a historical control group, we failed to find any differences in patient-reported outcomes.<\/jats:p><jats:p>\n          Level of Evidence\u2003IV \u2013 case series.<\/jats:p>","DOI":"10.1055\/s-0042-1757766","type":"journal-article","created":{"date-parts":[[2022,11,29]],"date-time":"2022-11-29T00:20:42Z","timestamp":1669681242000},"page":"324-330","source":"Crossref","is-referenced-by-count":4,"title":["Pyrocardan Implant Arthroplasty for Carpometacarpal Osteoarthritis of the Thumb: A Comparative Study with a Historical Control Group"],"prefix":"10.1055","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5734-9244","authenticated-orcid":false,"given":"Rasmus Wejnold","family":"J\u00f8rgensen","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Herlev-Gentofte University Hospital of Copenhagen, Hand Clinic, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiran Annette","family":"Anderson","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Herlev-Gentofte University Hospital of Copenhagen, Hand Clinic, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anders","family":"Odgaard","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Copenhagen, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claus Hjorth","family":"Jensen","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Herlev-Gentofte University Hospital of Copenhagen, Hand Clinic, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,11,28]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"324","DOI":"10.1016\/S0363-5023(86)80137-X","article-title":"Surgical management of basal joint arthritis of the thumb.
