Immature growth plate/apophysis injuries can occur in adolescents during sporting activity or due to repetitive trauma or overuse. In the pelvis, typical sites include the anterior iliac spines, trochanters, pubis or ischium. On radiographs, the cartilage bone interface fracture and subsequent healing with new bone can lead to bizarre appearances and awareness of these prevents misdiagnosis.

On MRI, there is an apophyseal injury pattern with edema at typical site and thickened apophysis. In some cases, a bony fracture may be seen.
