Tsou PY, Ma YK, Wang YH, et al. - A systematic review and meta-analysis were conducted to summarize the diagnostic accuracy of ultrasound for upper extremity fractures in children. Researchers carried out to search databases from inception through November 2019 applying pre-defined index terms, including “ultrasound,” “fractures of upper extremities” and “children”. The random-effects bivariate model was applied to conduct meta-analysis of the diagnostic accuracy of ultrasound for fractures. Meta-regression was carried out to ascertain whether the site of fracture influenced the diagnostic accuracy. This research distinguished 32 studies.The results demonstrate that in children, ultrasound has excellent diagnostic accuracy for non-elbow upper extremity fractures, serving as an alternative diagnostic modality to plain radiographs.
