Injuries were included if the athlete missed more than 2 days. All hip and groin injuries were included for evaluation. The authors also report on NFL players with intra-articular injuries seen at their institution outside of the NFL Injury Surveillance System.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>There were a total of 23 806 injuries from 1997 to 2006, of which 738 were hip injuries (3.1 %) with an average of 12.3 days lost per injury. Muscle strains were the most common injury. Intra-articular injuries resulted in the most time lost. Contact injuries most likely resulted in a contusion, and noncontact injuries most often resulted in a muscle strain. In the authors\u2019 institutional experience, many of the athletes with labral tears have persistent adductor strains that do not improve despite adequate therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Hip injuries represent a small but substantial percentage of injuries that occur in the NFL. A majority of these injuries are minor, with a return to play within 2 weeks. Intra-articular injuries are more serious and result in a significant loss of playing time. The \u201csports hip triad\u201d (labral tear, adductor strain, and rectus strain) is described as a common injury pattern in the elite athlete.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0363546508319898","type":"journal-article","created":{"date-parts":[[2008,7,18]],"date-time":"2008-07-18T21:28:19Z","timestamp":1216416499000},"page":"2187-2195","source":"Crossref","is-referenced-by-count":173,"title":["Hip Injuries and Labral Tears in the National Football League"],"prefix":"10.1177","volume":"36","author":[{"given":"Brian T.","family":"Feeley","sequence":"first","affiliation":[{"name":"Hospital for Special Surgery, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John W.","family":"Powell","sequence":"additional","affiliation":[{"name":"Michigan State University, East Lansing, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark S.","family":"Muller","sequence":"additional","affiliation":[{"name":"Hospital for Special Surgery, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronnie P.","family":"Barnes","sequence":"additional","affiliation":[{"name":"New York Giants, East Rutherford, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell F.","family":"Warren","sequence":"additional","affiliation":[{"name":"Hospital for Special Surgery, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryan T.","family":"Kelly","sequence":"additional","affiliation":[{"name":"Hospital for Special Surgery, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2008,7,18]]},"reference":[{"key":"bibr1-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/0363546504264159"},{"key":"bibr2-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/03635465010290042501"},{"key":"bibr3-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/0363546503258912"},{"key":"bibr4-0363546508319898","first-page":"450","volume":"106","author":"Blazina ME","year":"1967","journal-title":"Calif Med"},{"key":"bibr5-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1053\/jars.2002.30649"},{"key":"bibr6-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/0363546507308940"},{"key":"bibr7-0363546508319898","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200607000-00004"},{"key":"bibr8-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/036354659101900319"},{"key":"bibr9-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(78)90045-3"},{"key":"bibr10-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1097\/00007611-198307000-00014"},{"key":"bibr11-0363546508319898","first-page":"278","volume":"42","author":"Dick R","year":"2007","journal-title":"J Athl Train"},{"key":"bibr12-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9290(02)00365-2"},{"key":"bibr13-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9290(00)00042-7"},{"key":"bibr14-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2003.005736"},{"key":"bibr15-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2007.09.015"},{"key":"bibr16-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2362041987"},{"key":"bibr17-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/0363546503261737"},{"key":"bibr18-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2005.08.013"},{"key":"bibr19-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/036354658801600415"},{"key":"bibr20-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200301000-00008"},{"key":"bibr21-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000201168.72388.24"},{"key":"bibr22-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/03635465000280011501"},{"key":"bibr23-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2004.12.011"},{"key":"bibr24-0363546508319898","doi-asserted-by":"publisher","DOI":"10.1177\/036354659702500412"},{"key":"bibr25-0363546508319898","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200307000-00002"},{"key":"bibr26-0363546508319898","volume-title":"Injury Surveillance System","author":"National Collegiate Athletic Association (NCAA)","year":"2006"},{"key":"bibr27-0363546508319898","unstructured":"National Federation of State High School Associations.
