A<unk>  is a contusion (bruise) on the pelvis caused by a direct blow to an iliac crest. Contact sports are a frequent cause of this type of injury.
A<unk>  bruise usually causes bleeding into the<unk>  abductor muscles, which move legs sideways, away from the midline of the body. This bleeding into muscle tissue creates swelling and makes leg movement painful.
