Apophyseal Avulsion Fractures of the Pelvis and Lower Extremity


Apophyseal avulsion fractures of the hip and pelvis typically occur in patients between the ages of 14 and 25 years. The three most common locations of occurrence are the ischial tuberosity, anterior inferior iliac spine, and anterior superior iliac spine. Avulsion fractures of the greater trochanter, lesser trochanter, iliac crest, and pubic symphysis also occur, although much less frequently. These injuries can usually be diagnosed based on a thorough history and physical examination. Most avulsion fractures of the hip and pelvis can be detected on a standard AP pelvis radiograph. Pelvic apophyseal avulsion fractures are treated conservatively or surgically depending on the amount of displacement. Typical indications for surgical repair include displacement greater than 2 cm, non-unions, and painful exostosis.
