What is an anterior iliac spine avulsion?

An avulsion fracture is an injury to the bone in a place where a tendon or ligament attaches to the bone. In the anterior iliac spine which is part of the pelvis the common sites of avulsion fractures are at the attachment of:
  • Sartorius muscle to the anterior superior iliac spine
  • Rectus femoris to the anterior inferior iliac spine
In an avulsion fracture of the anterior iliac spine occurs, the sartorius muscle or the rectoris muscle (muscles in the front of the thigh) pulls off a piece of the bone in the anterior iliac spine where the thigh muscles attach. This commonly occurs in young athletes through the developing growth plate causing pain and swelling.

What causes an anterior iliac spine avulsion?

An anterior iliac spine avulsion is caused by sudden and forceful contraction of the sartorius and rectus femoris while the subject is engaged in a sporting event such as kicking a ball, running or jumping. Forceful extension at the hip can also lead to an avulsion injury.

Diagnosis of an anterior iliac spine avulsion

Diagnosis of an anterior iliac spine avulsion can be made following a detailed patient history, physical examination and x-ray.
