Segond fractures of the lateral tibial condyle

Description: Avulsion of a bony fragment from a point behind Gerdy's tubercle was originally described in cadaver experiments before the discovery of x-rays (Segond 1879). Since that time reports of this fracture in clinical practice have been scarce. Most authors have stressed the constant site and appearance of the avulsed tibial fragment (Dietz, Wilcox and Montgomery 1986) and the frequent association with anterior cruciate ligament disruption (Woods, Stanley and Tullos 1979). The present study was undertaken to establish the incidence of this injury, to investigate the apparent association with anterior cruciate ligament disruption and to determine the anatomical structure attached at the area of avulsion.
