Figure 1
Anteroposterior and cross-table lateral radiograph of the right hip joint in a 15-year-old male soccer player who presented with a painful swelling and suspected neoplasia of the right hip region. Both the avulsed osseous fragment (arrow) and the osseous irregularities at the anterior inferior iliac spine (asterisk) are well visualized, as this was not a tumor but an avulsion injury at the origin of the rectus femoris muscle.
