Nonunion of anterior inferior iliac spine avulsion fracture

Abstract

Avulsion fractures of the pelvis are usually observed in the skeletally immature population, particularly those who are involved in sports. Sprint running, sudden accelerating, and decelerating are the most common activities leading to avulsion fracture. This condition is more common in males than in females.[1] The occurrence mechanism of these fractures is sudden and strong contraction of the muscle attached to the apophysis.[2]
