We studied 32 fractures of the scaphoid one to two weeks after injury, by dynamic fat-suppressed T1-weighted gradient-echo MRI after the intravenous administration of gadopentetate dimeglumine (0.1 mmol\/kg body-weight). Steepest slope values (SSV) and percentage enhancement values (%E) were calculated for the distal and proximal fragments and poles. All the fractures were treated by immobilisation in a cast, and union was assessed by CT at 12 weeks. <\/jats:p><jats:p> Nonunion occurred in four fractures (12%), and there was no statistically significant difference between the proximal fragment SSV and %E values for the fractures which united and those with nonunion. The difference between the proximal pole SSV and %E values for the union and nonunion groups reached statistical significance (p &lt; 0.05), but with higher enhancement parameters for the nonunion group. Our results suggest that poor proximal vascularity is not an important determinant of union in fractures of the scaphoid. <\/jats:p>","DOI":"10.1302\/0301-620x.83b6.0830809","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T19:25:31Z","timestamp":1519241131000},"page":"809-814","source":"Crossref","is-referenced-by-count":109,"title":["Scaphoid blood flow and acute fracture healing"],"prefix":"10.1302","volume":"83-B","author":[{"given":"J.
