Fenoglio A, et al. - Via a retrospective cohort study of 72 adult patients (≥ 18 years) with isolated partial articular radial head fractures indicated for initial nonoperative treatment, experts assessed the utility of follow-up radiographs (OTA/AO 2R1B1 or 2R1B3). Initial radiographs were taken on average 2.6 days following an injury and follow-up radiographs 33.7 days thereafter. Equivalence tests assessing gap and step-off thresholds of < 1 mm were both important, symbolizing that the cohort displaced < 1 mm for both parameters between initial and follow-up radiographs. After the repeat radiographs, no patients moved to surgical treatment. Therefore, in comparison with initial radiographs, these fractures did not displace in the early postinjury period, as defined as a < 1 mm of change in both an intra-articular gap and step-off. However, with limited utility in identifying interval displacement or resulting in a change in management, routine follow-up radiographs for these injuries were a source of cost. Thus, in order to assess specific clinical concerns, selective use of radiographs may result in cost savings.
