Comparisons of shoulder function after treatment of floating shoulder injuries with different methods

This study aims to investigate appropriate treatment methods for floating shoulder injury (FSI). Fiftysix FSI patients treated from February 2006 to August 2014 were enrolled, and divided into three groups: a nonsurgical treatment group (Group A), a surgical treatment with single clavicular fixation group (Group B), and a surgical treatment with combined clavicular and scapular fixation group (Group C). The Herscovici FS efficacy scoring system and the Constant-Murley shoulder scoring systems were used to score affected shoulder functions. The variables of these three groups were compared with the one-way ANOVA. The follow-up was 17.1 months (6 to 30 months), and all fractures healed. The scores of the three groups had statistically significant differences. Regardless of the Herscovici or Constant scores, group A showed significant differences when compared with groups B and C, but there was no difference between groups B and C; however, there were significant differences in operative time and intraoperative blood loss. Surgery showed an obvious advantage for the restoration of shoulder functions in FSI patients; although the single clavicular fixation and the combined clavicular and scapular fixation showed no difference, single clavicular fixation had lower treatment risks
