Unplanned Operations and Adverse Events after Surgery for Diaphyseal Fracture of the Clavicle

Background: We used a database of patients treated at three hospitals to study the primary null hypothesis that there are no factors associated with unplanned reoperations or adverse events after surgical repair for diaphyseal clavicle fracture. Additionally we addressed the following secondary study questions: 1. What is the prevalence of unplanned reoperations or adverse events after surgical repair for diaphyseal clavicle fracture? 2. Is early implant loosening or breakage after surgical repair for diaphyseal clavicle fracture related to fixation type? 3. Is the type of fixation associated with the prevalence of brachial plexus palsy after surgical repair of a diaphyseal clavicle fracture? Methods: We retrospectively analyzed 249 adult patients who had surgery for a diaphyseal clavicle fracture to determine factors associated with unplanned reoperations or adverse events. Thirty-two patients (13%) had at least one unplanned reoperation or adverse event. Four of 249 patients (1.6%) developed early implant loosening or breakage. Patients that had local implant irritation, planned implant removal, or sensory symptoms thought to be due to nerve irritation were not included in the reported unplanned reoperations or adverse event rate. Results: Only female sex was associated with unplanned reoperations or adverse events after surgery for diaphyseal clavicle fracture. No other patient, technical, or injury related factors tested in this study were associated with unplanned reoperations or adverse events. Conclusion: Patients that have surgery for diaphyseal clavicle fracture have an approximately 13% risk of an unplanned second surgery or an adverse event. Women can be counseled that they are three times as likely as men to have an unplanned reoperations or adverse event. Level of evidence: III Keywords:
