Radiographs were obtained in athletes with a history of hip pain or injury. Anteroposterior pelvis and frog\u2010lateral radiographs were obtained in 123 hips (107 players) that met our inclusion criteria. Radiographic indicators of cam\u2010type FAI (alpha angle, head\u2010neck offset ratio) and pincer\u2010type FAI (acetabular retroversion, center\u2010edge angle, acetabular inclination) were recorded. Findings were correlated with clinical factors (previous groin\/hip pain, position, race, and body mass index).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The most common previous injuries included groin strain (n = 57) and sports hernia\/abdominal strain (n = 21). Markers of cam\u2010 and\/or pincer\u2010type FAI were present in 94.3% of hips (116 of 123). Radiographic evidence of combined cam\u2010 and pincer\u2010type FAI was the most common (61.8%, 76 hips), whereas isolated cam\u2010type FAI (9.8%, 12 hips) and pincer\u2010type FAI (22.8%, 28 hips) were less common. The most common deformities included acetabular retroversion (71.5%) and an abnormal alpha angle (61.8%). A body mass index greater than 35 was associated with the presence of global overcoverage (46.2%\n                      <jats:italic>v<\/jats:italic>\n                      17.3%,\n                      <jats:italic>P<\/jats:italic>\n                      = .025).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Radiographic indicators of FAI are very common among athletes evaluated at the National Football League Scouting Combine subjected to radiographic examination for the clinical suspicion of hip disease. Elite football athletes with significant or recurrent pain about the hip should be evaluated clinically and radiographically for FAI, because pain from FAI may be falsely attributed to or may be
