    IntroductionThe aim of this study was to present a modified Murray and Schwarz 2.5-mm Kirschner wire (K-wire) intramedullary (IM) technique for fixation of displaced midshaft clavicle fractures (DMCF), and to compare the differences in treatment outcome of two-part (Robinson 2B.1) and multifragmentary (Robinson 2B.2) DMCF.MethodsA retrospective analysis of 91 patients who underwent IM fixation with a 2.5-mm K-wire for DMCF and had a 1-year post-operative follow-up between 2000 and 2012 was performed. The patients were allocated into two groups: Robinson 2B.1 (n = 64) and Robinson 2B.2 (n = 27). Assessed outcomes were non-union, reoperation rate, wire migration and infection.ResultsThere was no statistically significant difference in the rate of non-union (2B.1,2B.2; 3.13%, 7.41%; p = 0.365), reoperation (2B.1, 2B.2; 3.13%, 7.41%; p = 0.365), K-wire migration (2B.1, 2B.2; 0.00%, 0.00%; p = 1.00) and clavicle shortening at 12-months (2B.1, 2B.2; 3.13%, 7.41%; p = 0.365).ConclusionIntramedullary clavicle fixation with a 2.5-mm K-wire is a safe surgical technique. 2B.1 injuries treated with 2.5-mm IM K-wire fixation have relatively improved outcome compared with displaced 2B.2 fractures for both non-union and reoperation rates. There were no occurrences of implant migration with either 2B.1 or 2B.2 injuries, and a non-significant difference in implant irritation was documented with IM K-fixation. The non-union rate with K-wire IM fixation of 2B.1 injuries concords with the published results of other IM devices and thus this technique should be added to the surgeon's armamentarium when considering surgical treatment of such injuries.© 2017 Elsevier Ltd.
