INTRODUCTION: Simultaneous ipsilateral clavicle and acromioclavicular (AC) @entity130 have been infrequently reported in the literature at this time. The purpose of this study was to assess incidence as well as assess risk factors for this dual injury pattern. METHODS: We performed a retrospective review of a prospectively collected database (Level III evidence), evaluating 383 adult @entity1 without previous shoulder @entity130 or @entity130 with a minimum 1-year follow-up who sustained a displaced @entity174 . All @entity1 in the study underwent either nonoperative management or surgical reduction and stabilization of a @entity174 with a plate and screw construct. Study subjects were followed with serial radiographs. Clavicle and shoulder radiographs, as well as chest radiographs and contralateral films in questionable cases, were used to assess for @entity130 in both operative and nonoperative groups. Additional data was collected on concurrent injuries, @entity1 demographics, @entity174 characteristics, fixation techniques, surgical/post-operative data, and operative or nonoperative treatment. RESULTS: We found that 13/183 (7.1%) of @entity1 undergoing fixation of a @entity174 had an ipsilateral @entity130 , while 13/200 (6.5%) of @entity1 undergoing conservative management had an ipsilateral @entity130 . Critical analysis of the data revealed that presence of @entity174 , and a likely incidental association with superior plating fixation, were associated with an increased rate of this injury pattern. CONCLUSIONS: Ipsilateral @entity174 and @entity130 is much more common than traditionally believed, with an incidence of 6.8% overall. It is unknown how the presence of an associated AC injury influences outcome, as AC injury was not universally symptomatic.
