The aim of this study was to: (1) assess factors influencing active thumb interphalangeal (IP) joint flexion; and (2) assess the factors associated with reoperation. Methods: Retrospectively, 104 patients with primary repair of a Zone II FPL laceration from 2000 to 2016 were identified. A medical chart review was performed to collect patient-, injury-, and surgery characteristics as well as the degree of postoperative active IP-flexion and occurrence of reoperation. Bivariate analyses were performed to identify factors influencing active IP-flexion and factors associated with reoperation. Results: The reoperation rate was 17% (n = 18) at a median of 3.4 months (range: 2.3-4.4). Indications for reoperation mainly included adhesion formation (n = 10, 56%) and re-rupture (n = 5, 28%). The median range of active IP-flexion was 30\u00b0 (interquartile range [IQR]: 20-45) at a median of 12.4 weeks (IQR: 8.1-16.7). Solitary injury to the thumb (\u03b2 = 17.9, P = .022) and the use of epitendinous suture (\u03b2 = 10.0, P = .031) were associated with increased active IP-joint flexion. No factors were statistically associated with reoperation. Conclusions: About 1 in 5 patients undergo reoperation following primary repair of a Zone II FPL laceration, mostly within 6 months of initial surgery. The use of epitendinous suture is associated with greater active IP-flexion. Patients with multiple digits injured accompanying a Zone II FPL laceration have inferior IP-joint motion.<\/jats:p>","DOI":"10.1177\/1558944720930294","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T08:37:49Z","timestamp":1593592669000},"page":"285-292","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Zone II Flexor Pollicis Longus Repair: Thumb Flexion and Complications"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5680-0344","authenticated-orcid":false,"given":"Luca L.","family":"Bruin","sequence":"first","affiliation":[{"name":"Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6159-4645","authenticated-orcid":false,"given":"Jonathan","family":"Lans","sequence":"additional","affiliation":[{"name":"Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5397-8147","authenticated-orcid":false,"given":"Kyle R.","family":"Eberlin","sequence":"additional","affiliation":[{"name":"Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7527-1110","authenticated-orcid":false,"given":"Neal C.","family":"Chen","sequence":"additional","affiliation":[{"name":"Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,7,1]]},"reference":[{"key":"bibr1-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.cps.2019.02.003"},{"key":"bibr2-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1177\/1753193417723238"},{"key":"bibr3-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.jht.2015.04.002"},{"key":"bibr4-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.jht.2017.12.007"},{"key":"bibr5-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2011.11.006"},{"key":"bibr6-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1177\/1753193408091570"},{"key":"bibr7-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.02.003"},{"key":"bibr8-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.09.021"},{"key":"bibr9-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1111\/vsu.13268"},{"key":"bibr10-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(96)80106-7"},{"key":"bibr11-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1016\/j.cps.2014.03.009"},{"key":"bibr12-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1111\/vsu.13266"},{"key":"bibr13-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1053\/jhsu.2001.24959"},{"key":"bibr14-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/4063137"},{"key":"bibr15-1558944720930294","doi-asserted-by":"publisher","DOI":"10.1142\/S0218810405002826"}],"container-title":["HAND"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944720930294","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1558944720930294","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944720930294","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T07:27:00Z","timestamp":1777447620000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1558944720930294"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,7,1]]},"references-count":15,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022,3]]}},"alternative-id":["10.1177\/1558944720930294"],"URL":"https:\/\/doi.org\/10.1177\/1558944720930294","relation":{},"ISSN":["1558-9447","1558-9455"],"issn-type":[{"value":"1558-9447","type":"print"},{"value":"1558-9455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,7,1]]}}}
