“…The study concluded that radiographic view, choice of anatomic landmarks, patient age, forearm position, and observer bias all affect where the RCL intersects the capitellum. In addition, a recent study by Ramirez et al,19 demonstrated that, in 116 pediatric elbow radiographs without signs of injury, the radiocapitellar line fell outside the central third of the capitellum 50% of the time and missed the capitellum completely 15.6% of the time. Despite the results of these studies, which question the use of the RCL as a valid and reliable tool in the pediatric patient, little research has been carried out on the reason for its inaccuracy.…”
