he incidence of groin pain among athletes is estimated to be from 2% to 20%; however, the incidence in the general population is unknown. Groin hernias and hip joint pathologic findings are common and often considered; once ruled out by physical examination with or without imaging, the differential diagnoses and workup of groin pain is confounding to many practitioners. This ambiguous nature of nonhernia, nonhip groin pain is understandable because routine physical examination often only reveals groin tenderness, and imaging may or may not have abnormalities. Most of the literature written about the subject are case series or opinions. Many of these case series only involve professional male athletes, and the reported end points are often: return to sport, time to return to sport, or level of sport. Thus, the level of evidence of the studies is low quality, and the findings may not be applicable to the general population. In the past 2 decades, treating practitioners have attempted to better classify and describe the common pattern of symptoms, examination and imaging findings, and noted anatomic abnormalities at the time of operative management. Common lexicon is necessary so that meaningful comparisons can be made. 1 The literature search for this narrative review is highlighted in the eFigure in the Supplement.Various nomenclature has been used for nonhernia, nonhip groin pain including athletic pubalgia, sports hernia, core muscle injury, Gilmore groin, sportsman groin, inguinal disruption, and several others. [2][3][4][5] Inclusion of the word hernia in the jargon is misrepresentative. We prefer the broad but descriptive term groin pain syndrome.
