Abstract

We present here an unusual case of a sequential avulsion fracture of the anterior inferior iliac spine (AIIS), occurring first in the right and then the left AIIS, during long jump attempts. The case of a 17 year old boy with pain around his right groin, which first occurred during a long jump attempt, is presented. Radiographic examination revealed an avulsion fracture of the right AIIS. After conservative treatment, full athletic activity was allowed 2 months after the injury. However, 4 months later the patient returned with a similar pain in the opposite side of his groin. Radiographs revealed another fracture of the left AIIS. The boy underwent the same treatment protocol; he was examined with isokinetic dynamometry. No complication or re-injury occurred during the 2 year follow up period. In the present study, we introduce the first case of a sequential bilateral AIIS avulsion fracture caused by a long jump.
