However, a few reports have shown that the PIP ROM tends to decline with longer follow-up. The goal of this study is to assess the results of at least 5 years of follow-up of SRA through a volar approach and also to investigate the cause of deterioration of ROM with time after SRA through this approach. Methods: Eleven fingers with degenerative osteoarthritis that underwent SRA through the volar approach were examined. ROM of the PIP joint preoperation, 1 year after the surgery, and at final follow-up was measured and statistically analyzed. Also, the relationship between PIP ROM and the osteophyte developed postoperatively was examined. Results: The average follow-up period was 7.3 years. The average PIP ROM of the PIP joints was 52.3\u00b0 preoperatively, 54.1\u00b0 at 1 year postoperatively, and 31.1\u00b0 at the final follow-up. PIP ROM at the final follow-up was significantly decreased compared with that preoperatively or at 1 year postoperatively. Also, the development of an osteophyte was negatively correlated with the ROM of the PIP joint at the final follow-up. Conclusions: PIP ROM after SRA through a volar approach has the tendency to deteriorate with a longer follow-up. Development of an osteophyte is considered to be a main risk factor of deterioration in the cases of SRA through a volar approach.<\/jats:p>","DOI":"10.1177\/1558944718787332","type":"journal-article","created":{"date-parts":[[2018,7,17]],"date-time":"2018-07-17T09:59:59Z","timestamp":1531821599000},"page":"81-86","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Surface Replacement Arthroplasty Using a Volar Approach for Osteoarthritis of Proximal Interphalangeal Joint: Results After a Minimum 5-Year Follow-up"],"prefix":"10.1177","volume":"15","author":[{"given":"Ken","family":"Shirakawa","sequence":"first","affiliation":[{"name":"Saitama Red Cross Hospital, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiko","family":"Shirota","sequence":"additional","affiliation":[{"name":"Saitama Red Cross Hospital, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,7,17]]},"reference":[{"key":"bibr1-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2006.10.017"},{"key":"bibr2-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.06.006"},{"key":"bibr3-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1142\/S0218810414500130"},{"key":"bibr4-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1097\/BTH.0b013e31818c0f71"},{"key":"bibr5-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jormas.2017.03.002"},{"key":"bibr6-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2014.11.015"},{"key":"bibr7-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1177\/1558944717726136."},{"key":"bibr8-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(97)80165-7"},{"key":"bibr9-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1177\/1753193412443044"},{"key":"bibr10-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/S1063-4584(97)80003-9"},{"key":"bibr11-1558944718787332","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.J.01375"},{"key":"bibr12-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2011.06.002"},{"key":"bibr13-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1142\/S2424835516500326"},{"key":"bibr14-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2011.03.003"},{"key":"bibr15-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(85)80154-4"},{"key":"bibr16-1558944718787332","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.J.00832"},{"key":"bibr17-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1177\/1558944716662020"},{"key":"bibr18-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2006.11.006"},{"key":"bibr19-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2015.05.021"},{"key":"bibr20-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.02.012"},{"key":"bibr21-1558944718787332","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2017.01.079"}],"container-title":["HAND"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944718787332","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1558944718787332","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944718787332","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T07:29:32Z","timestamp":1777447772000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1558944718787332"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,7,17]]},"references-count":21,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2020,1]]}},"alternative-id":["10.1177\/1558944718787332"],"URL":"https:\/\/doi.org\/10.1177\/1558944718787332","relation":{},"ISSN":["1558-9447","1558-9455"],"issn-type":[{"value":"1558-9447","type":"print"},{"value":"1558-9455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,7,17]]}}}
