Lauge-hansen classification of malleolar fractures: An assessment of the reproducibility in 118 cases

Abstract

The radiographs of malleolar fractures in 118 consecutive patients were assessed by 4 observers using the Lauge-Hansen classification. the interobserver variation was large; only 51 of the 118 radiographs were classified identically by all 4 observers. With the purpose of assessing intraobserver variation, the same observers classified the same radio-graphs 6 weeks later. the first and the second classification were identical in 75-97 of 118 radiographs (64-82 percent). These results show that the Lauge-Hansen system is difficult to apply in a reproducible way. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
