Biplanar fluoroscopy allows for the simultaneous acquisition of x-ray images in 2 planes without needing to move the extremity or C-arm. It is advantageous in cases such as pinning supracondylar humerus fractures or slipped capital femoral epiphyses where frequently alternating between 2 planes under fluoroscopic imaging is required. However, literature describing the technique is lacking. Therefore, the purpose of our article is to discuss room setup, advantages, and disadvantages of using biplanar fluoroscopy in cases involving the elbow, shoulder, hip, and knee.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
