To reduce the risk of avascular necrosis (AVN), treatment involved simultaneous anatomic reduction and internal fixation of the fracture and vascularized bone graft (VBG) for the scaphoid proximal pole. At 4 months, magnetic resonance imaging and 36 months of follow-up radiography showed a healed scaphoid and revealed no evidence of AVN in the scaphoid proximal pole.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>If the risk of AVN is high, we recommend considering the combination of internal fixation and VBG for the fresh scaphoid fracture.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.21.00081","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T15:00:16Z","timestamp":1626102016000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Primary Vascularized Bone Graft for the Extruded Scaphoid Proximal Pole"],"prefix":"10.2106","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4901-9442","authenticated-orcid":false,"given":"Masahiko","family":"Tohyama","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka Rosai Hospital, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8768-3048","authenticated-orcid":false,"given":"Nobuo","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka General Hospital of West Japan Railway Company, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5369-557X","authenticated-orcid":false,"given":"Sadahiko","family":"Konishi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka General Hospital of West Japan Railway Company, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,7]]},"reference":[{"issue":"2","key":"bib1-20240805","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1177\/1558944717736397","article-title":"Bone grafting for scaphoid nonunions: is free vascularized bone grafting superior for scaphoid nonunion?","volume":"14","author":"Aibinder","year":"2019","journal-title":"Hand (N Y)."},{"issue":"3","key":"bib2-20240805","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1055\/s-0036-1597575","article-title":"A critical appraisal of vascularized bone grafting for scaphoid nonunion","volume":"6","author":"Alluri","year":"2017","journal-title":"J Wrist Surg."},{"issue":"3","key":"bib3-20240805","doi-asserted-by":"crossref","first-page":"507","DOI":"10.1053\/jhsu.2000.5993","article-title":"Free vascularized bone graft for nonunion of the scaphoid","volume":"25","author":"Doi","year":"2000","journal-title":"J Hand Surg Am."},{"issue":"8","key":"bib4-20240805","doi-asserted-by":"crossref","first-page":"800","DOI":"10.1016\/j.otsr.2011.08.008","article-title":"Vascularized bone graft pedicled on the volar carpal artery from the volar distal radius as primary procedure for scaphoid non-union","volume":"97","author":"Gras","year":"2011","journal-title":"Orthop Traumatol Surg Res."},{"issue":"12","key":"bib5-20240805","doi-asserted-by":"crossref","first-page":"2616","DOI":"10.2106\/JBJS.G.01503","article-title":"Treatment of scaphoid waist nonunions with an avascular proximal pole and carpal collapse.
