ISOLATED FRACTURE OF THE TROCHLEA: REPORT OF TWO CASES WITH REVIEW OF THE LITERATURE ON THE MECHANISM OF INJURY

INTRODUCTION: Also called as Laugier’s fracture, isolated fracture of the humeral trochlea is a rare clinical entity1. Trochlear fracture is usually associated with dislocation of the elbow2 .The exact mechanism causing this peculiar type of fracture is not known precisely. We present two cases of isolated displaced fracture of the trochlea treated by open reduction and internal fixation. The literature regarding the mechanism of injury is reviewed.
