 Dr. P here, we've got some cool anatomy in front of you, but I want to focus on the symptoms of sports hernia syndrome, or sports hernia, because many people find this an enigmatic diagnosis. As we've said before, it's not a true hernia. It's not an umbilical hernia, a spagallion hernia, a pettus hernia, there's all kinds of hernias, including a direct hernia. But in this syndrome, there isn't a palpable defect with anything going through it. It is a weakness due to repetitive overuse syndrome, and who gets it, elite, twisting, turning athletes who generate power. Now what are the symptoms? The classic symptom of sports hernia is groin pain. Now those of you that do musculoskeletal imaging and are musculoskeletal clinicians know that groin pain can be caused by a whole host of things, like lumbar disc disease. It can be caused by a labral tear. In fact, I've had innumerable labral tears, at least five, that presented as sports hernia syndrome. What else do they get? Cubic pain, diminished function, the inability to generate power, speed, force. They also may have symptoms that cross the midline, which is rather bizarre and enigmatic to the clinician. The pain is usually a dull pain. Occasionally it's burning, and frequently that groin pain will extend into the inner thigh or the scrotum. And then when you do imaging, initially, in the hands of a non-expert, it's normal. Let's move on.
