Retrospective cohort study of 52 adults with completely displaced middle-third clavicle fractures treated nonoperatively. Asked: how often do these injuries fail conservative management, and which factors predict failure? Mean follow-up was 38 months.
The 0.4% nonunion rate quoted for decades came from series of over 3000 fractures that pooled children with adults, nondisplaced with displaced, and all thirds together — a comparison group that bears little resemblance to the adult with a visibly displaced midshaft fracture in your trauma bay.
This paper isolated that highest-risk subgroup and showed the real numbers: 15% nonunion, 31% dissatisfied. When you see a completely displaced mid-clavicle fracture in an adult, measure the shortening on the injury film. If shortening is ≥20 mm, every single patient in this series developed nonunion with conservative care. That is a concrete operative indication, not a relative one.
Even patients who heal with ≥20 mm of final shortening report dissatisfaction at significantly higher rates, so the goal is not just union but anatomic length restoration. This paper is foundational to the modern shift toward operative fixation for displaced clavicle fractures, and the 20 mm shortening threshold remains a core decision point in contemporary trauma guidelines.
