Methods: Data from the National High School Sports\u2014Related Injury Surveillance Study were analyzed to calculate rates, describe patterns, and evaluate potential risk factors for player\u2014player contact injuries. Results: Player\u2014player contact injuries represented 46.4% of all high school sports injuries and occurred at a rate of 11.6 per 10 000 athlete exposures (AEs). Player\u2014player contact injury rates (per 10 000 AEs) were highest in football (26.0), wrestling (10.8), and girls\u2019 soccer (9.8). Body sites most commonly injured were the ankle\/foot (21.9%), head\/face (18.9%), and knee (16.9%). Most common diagnoses were ligament sprains (32.5%). Conclusions: Player\u2014player contact is the most common mechanism of injury among high school athletes. The epidemiology of such injuries varies by gender and sport. Developing effective preventive measures depends on increasing our knowledge of player\u2014player contact injury rates, patterns, and risk factors.<\/jats:p>","DOI":"10.1177\/0009922810390513","type":"journal-article","created":{"date-parts":[[2010,12,31]],"date-time":"2010-12-31T20:14:06Z","timestamp":1293826446000},"page":"594-603","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":42,"title":["Epidemiology of Player\u2014Player Contact Injuries Among US High School Athletes, 2005-2009"],"prefix":"10.1177","volume":"50","author":[{"given":"Zachary Y.","family":"Kerr","sequence":"first","affiliation":[{"name":"The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christy L.","family":"Collins","sequence":"additional","affiliation":[{"name":"The Research Institute at Nationwide Children's Hospital, Columbus, OH, USA,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah K.","family":"Fields","sequence":"additional","affiliation":[{"name":"The Ohio State University, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Dawn Comstock","sequence":"additional","affiliation":[{"name":"The Ohio State University, Columbus, OH, USA, The Research Institute at Nationwide Children's Hospital, Columbus, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,12,30]]},"reference":[{"key":"atypb1","unstructured":"National Federation of State High School Associations.
