Fracture surfaces were identified and fragment volumetric size of the fracture fragments was measured. A principal component analysis was used to find groups. Density mapping was used to image probable common fracture areas in the scaphoid.<\/jats:p><jats:p>\n          Results\u2003Forty-nine of 51 fractures had a similar pattern. It was not possible to identify subgroups based on fracture pattern. The mean volumetric size of the fracture fragments of the proximal (1.45\u2009cm3\u2009\u00b1\u20090.49\u2009cm3 standard deviation [SD]) and distal fracture fragments (1.53\u2009cm3\u2009\u00b1\u20090.48\u2009cm3 SD) was similar. There was a single common fracture area in the middle third of the bone. In the distal third, there were no horizontal fractures through\u2014but only directly proximal to\u2014the tubercle suggesting that these would be best classified as distal waist fractures.<\/jats:p><jats:p>\n          Conclusion\u2003Acute scaphoid fractures mainly occur in the middle third of the bone and tend to divide the scaphoid in half by volumetric size of the fracture fragments. There were two distinct grouping patterns: fractures through the proximal and middle third were horizontal oblique, whereas fractures of the distal third were vertical oblique. It seems that scaphoid fractures might be classified into proximal pole fractures, a range of waist fractures, and tubercle avulsion fractures.<\/jats:p><jats:p>\n          Level of evidence\u2003This is a Level IV study.<\/jats:p>","DOI":"10.1055\/s-0039-1693050","type":"journal-article","created":{"date-parts":[[2019,7,8]],"date-time":"2019-07-08T22:47:51Z","timestamp":1562626071000},"page":"441-445","source":"Crossref","is-referenced-by-count":4,"title":["Scaphoid Fracture Patterns\u2014Part One: Three-Dimensional Computed Tomography Analysis"],"prefix":"10.1055","volume":"08","author":[{"given":"Tessa","family":"Drijkoningen","sequence":"additional","affiliation":[{"name":"Hand and Upper Extremity Service, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amin","family":"Mohamadi","sequence":"additional","affiliation":[{"name":"Hand and Upper Extremity Service, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shai","family":"Luria","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Hadassah-Hebrew University Medical Center, Jerusalem, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geert A.","family":"Buijze","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Academic Medical Center, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2019,7,8]]},"container-title":["Journal of Wrist Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-1693050.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,12,4]],"date-time":"2019-12-04T23:38:44Z","timestamp":1575502724000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-1693050"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,8]]},"references-count":0,"journal-issue":{"issue":"06","published-online":{"date-parts":[[2019,12,4]]},"published-print":{"date-parts":[[2019,12]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-1693050","relation":{},"ISSN":["2163-3916","2163-3924"],"issn-type":[{"value":"2163-3916","type":"print"},{"value":"2163-3924","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,7,8]]}}}
