An Anterior Inferior Iliac Spine Avulsion Fracture in a 14-Year Old Boy on Human Growth Hormone.

We present the case of a young man with an anterior inferior iliac spine (AIIS) avulsion fracture who was taking human growth hormone (HGH) at the time his injury was diagnosed. He presented with chronic hip pain and no traumatic event. Physical exam revealed symptoms of hip impingement. Upon imaging, he was diagnosed with an AIIS avulsion fracture and underwent surgical repair. He returned to full activity six months post-operatively. At 18-months post-operatively, he was pain-free and performing all activities without difficulty. The role of HGH in his injury or recovery is not well understood and must be studied with large database studies.
