Apophyseal avulsion fractures of the pelvis and hip are relatively common among physically active adolescents and young adults.

Epidemiology

Pelvic and hip apophyseal injuries typically occur in the 14 to 25 year age range. Kicking sports, such as soccer, and gymnastics are frequently to blame.

Pathology

Sudden forceful muscular contraction causes the apophysis to which the tendon attaches to avulse.

Sites of avulsion

iliac crest avulsion: anterior abdominal wall muscles
anterior superior iliac spine (ASIS) avulsion: tensor fascia lata and sartorius
anterior inferior iliac spine (AIIS) avulsion: straight head of rectus femoris
greater trochanter avulsion: hip rotator cuff
lesser trochanter avulsion: iliopsoas muscle
ischial tuberosity avulsion: ~~hamstring~~ hamstring muscles
body and inferior ramus of pubic bone: thigh adductors and gracilis
