Implication

Reliability analysis reveals consistent Herring lateral pillar grading across surgeon experience levels in Perthes disease, indicating high reproducibility of this radiographic method.

Key Points

To evaluate the effect of surgeons' pediatric orthopaedic experience on the intraobserver and interobserver reliability of the Herring lateral pillar classification in Perthes disease.
Five observers with varying levels of pediatric orthopaedic experience classified anteroposterior (AP) pelvis radiographs of 33 patients in the fragmentation phase of Perthes disease on three separate occasions at least 24 hours apart.
Frog-leg lateral-view radiographs were classified using the same criteria applied to the anterior column of the femoral head.
Interobserver and intraobserver reliability were evaluated across reading sessions using kappa statistics.
Kappa statistics showed good agreement for both intraobserver and interobserver reliability on AP and frog-leg lateral radiographs, with no statistically significant variations among reviewers of differing experience levels.
Twenty-four percent of evaluated cases were classified one grade worse on the frog-leg lateral radiograph compared to the AP view.
