Orthopaedic journals with a higher impact factor are more likely to publish Level-I or II articles. The type and level of information in orthopaedic journals can be reliably classified, and clinical investigators should pursue studies with a higher level of evidence whenever feasible.

Intraobserver agreement with regard to measurement of displacement of medial epicondyle fractures of the humerus varied among the reviewers but was low overall. Interobserver agreement was best for the measurements on the anteroposterior radiographs, but this was also low overall. These findings cast doubt on whether the amount of perceived displacement should be used as a criterion for choosing operative or nonoperative management of fractures of the humeral medial epicondyle. Agreement may be improved to acceptable levels by adopting a standard set of measurement guidelines, which include use of the anteroposterior radiograph when possible and consistently measuring at the point of maximal displacement.
