Poor reproducibility of evans' classification of the trochanteric fracture: Assessment of 4 observers in 52 cases

Abstract

The radiographs of trochanteric fractures in 52 consecutive patients were assessed by 4 observers, using the Evans' classification. the interobserver variation was large; only 23 of 52 radiographs were classified identically by all 4 observers. When only assessing stability, the 4 observers agreed in 34 of 52 radiographs. To assess the intraobserver variation, the same observers classified the same radiographs 6 weeks later. the first and second classifications were identical in 35-44 of 52 radiographs. © 1993 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
