After eliminating cases with our exclusion criteria, the study cohort had 40 cases for analysis. A comparison and analysis of union rates was undertaken between the fully threaded Acutrak 2 mini screw and the smooth shaft Herbert screw.<\/jats:p><jats:p>Results: Overall union rate for screw fixation was 88%. The fully threaded conical screw fixation had a significantly lower union rate of 50% compared to 97% for the smooth shaft screws.<\/jats:p><jats:p>Conclusions: Our data revealed that the fully threaded conical screws were associated with significantly lower union rate compared to the smooth shaft Herbert type screws.<\/jats:p>","DOI":"10.1142\/s0218810415500239","type":"journal-article","created":{"date-parts":[[2015,6,8]],"date-time":"2015-06-08T07:20:28Z","timestamp":1433748028000},"page":"273-279","source":"Crossref","is-referenced-by-count":5,"title":["The Effect of Screw Design on Union Rates in Scaphoid Nonunions"],"prefix":"10.1142","volume":"20","author":[{"given":"Jiwei","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Hand Surgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shian Chao","family":"Tay","sequence":"additional","affiliation":[{"name":"Department of Hand Surgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander Y.","family":"Shin","sequence":"additional","affiliation":[{"name":"Division of Hand Surgery, Mayo Clinic, Rochester, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2015,6,8]]},"reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1177\/145749690809700402"},{"issue":"4","key":"p_2","first-page":"271","volume":"64","author":"Anand Panchal D.O.","year":"2007","journal-title":"Comparison of Fixation Methods for Scaphoid Nonunions.
