1 A, B: Avulsions of right and left anterior inferior iliac spines in a skeletally immature boy. A: AP pelvis radiographic image obtained at initial presentation shows avulsions of the right (arrow) and left (arrowhead) anterior inferior iliac spines. Mild distraction or displacement, as on the right, is typical of these injuries. A somewhat unusual degree of displacement is seen on the left. B: Follow-up AP pelvis image, obtained four months after image (A). Right (arrow) and left (arrowhead) avulsions are healing. On the left, healing includes retraction of the fragment towards its normal location and abundant heterotopic ossification. Source: Chapter 8.
