Pediatric Pelvis and Hip Apophyseal Avulsion Fracture

  • Etiology: avulsion of insertion of muscle leads to avulsion fracture
  • Imaging: iliac crest avulsion is where abdominal muscles insert, anterior superior iliac spine is where sartorius muscle inserts, anterior inferior iliac spine is where rectus femoris muscle inserts, symphysis pubis is where adductor group inserts, greater trochanter is where gluteal muscles insert, lesser trochanter is where iliopsoas muscle inserts, ischial tuberosity is where hamstring muscles insert
