BackgroundThe objective of the present study was to the determine the accuracy of point-of-care ultrasound (POCUS) in assessing closed reduction (CR) of pediatric forearm fractures in a pediatric emergency setting.MethodsAfter determination of the need for CR using X-ray images by an orthopedic consultant, POCUS examinations were performed just before and after the reduction attempt. The transducer was positioned longitudinally over the dorsal, volar, and lateral surfaces of the radius and ulna to view the fracture site. The presence of angulation, displacement, or bayonetting of the fracture fragments was recorded. The adequacy of realignment according to the POCUS and the orthopedic consultant's final determination were recorded.ResultsSixty-two patients were enrolled in the study and 96 bones were evaluated. The sensitivity and specificity of POCUS for adequacy of CR were 95.8% [95% confidence interval (CI): 88.3-99.1)] and 95.8% (95% CI: 78.8-99.8), the positive predictive value was 98.5% (95% CI: 91.0-99.7), and the negative predictive value was 88.4% (95% CI: 71.6-95.8). The corresponding positive and negative likelihood ratios were 23 (3.37-156.77) and 0.04 (0.01-0.12). There was high agreement between POCUS and X-ray images for predicting adequacy of CR [κ: 0.892 (±0.053)]. There was also a significant correlation between POCUS and X-ray measurements of angulation and displacement performed before and after CR, respectively (p < 0.001).ConclusionOur study has reported the successful use of POCUS for the management of pediatric forearm fractures in a pediatric emergency department. Point-of-care ultrasound can minimize radiation exposure and appears to be an alternative and accurate tool for reduction attempts.Copyright © 2021 Elsevier Inc. All rights reserved.
