Ankle injuries causing a loss of more than 48 h training were studied, along with the setting and mechanism of injury, the diagnosis, time to rehabilitate, any investigations and surgical treatment. The incidence of injury per 1000 h exposure in match, training and in total was calculated.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 56 (incidence 14%) new ankle injuries were identified during this 1-year study period. Twenty-six (46%) of these occurred in competition, 24 (43%) were by contact, and eight (14%) had a severe injury diagnosed. The incidence was higher in the competitive setting. Ten injuries (18%) missed more than 6 weeks' training. Of these, seven were diagnosed as \u2018sprain\u2019 or \u2018strain,\u2019 of whom only three had been further investigated. There was a significant relationship between injury incidence and age group for total and match exposure, but not for training exposure.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The incidence of ankle injury in youth soccer is higher in competition, and increases with age in competition. 17.5% of ankle injuries missed more than 6 weeks' training, but the authors found a subgroup of players with delay in returning to sport in whom there was no further investigation to establish the diagnosis. This group may harbour occult injury to the chondral surfaces, and earlier investigation could minimise secondary joint damage in this \u2018at risk\u2019 age group.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bjsm.2009.067900","type":"journal-article","created":{"date-parts":[[2010,5,29]],"date-time":"2010-05-29T20:24:09Z","timestamp":1275164649000},"page":"702-708","source":"Crossref","is-referenced-by-count":26,"title":["Ankle injuries in football academies: a three-centre prospective study"],"prefix":"10.1136","volume":"45","author":[{"given":"David J","family":"Cloke","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phil","family":"Ansell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Avery","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Deehan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2010,5,29]]},"reference":[{"key":"2025080113593292000_45.9.702.1","unstructured":"FIFA \u2018The Big Count.\u2019 2007. http:\/\/www.fifa.com\/worldfootball\/bigcount\/index.html (Accessed 19 December 2008)."},{"key":"2025080113593292000_45.9.702.2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.33.3.196"},{"key":"2025080113593292000_45.9.702.3","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506294857"},{"key":"2025080113593292000_45.9.702.4","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.89B1.18427"},{"key":"2025080113593292000_45.9.702.5","doi-asserted-by":"publisher","DOI":"10.2165\/00007256-199418010-00006"},{"key":"2025080113593292000_45.9.702.6","doi-asserted-by":"crossref","first-page":"564","DOI":"10.1111\/j.1600-0838.2006.00594.x","article-title":"Biological maturity and injury in elite youth football","volume":"17","author":"Le Gall","year":"2007","journal-title":"Scand J Med Sci Sports"},{"key":"2025080113593292000_45.9.702.7","doi-asserted-by":"publisher","DOI":"10.1177\/036354657800600608"},{"key":"2025080113593292000_45.9.702.8","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2003.005165"},{"key":"2025080113593292000_45.9.702.9","doi-asserted-by":"publisher","DOI":"10.1177\/036354658000800505"},{"key":"2025080113593292000_45.9.702.10","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-003-0343-1"},{"key":"2025080113593292000_45.9.702.11","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.37.3.233"},{"key":"2025080113593292000_45.9.702.12","doi-asserted-by":"publisher","DOI":"10.1007\/s004310050011"},{"key":"2025080113593292000_45.9.702.13","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.1988.02150080045019"},{"key":"2025080113593292000_45.9.702.14","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.b490"},{"key":"2025080113593292000_45.9.702.15","doi-asserted-by":"publisher","DOI":"10.1177\/0363546505283271"},{"key":"2025080113593292000_45.9.702.16","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-5898(03)00006-3"},{"key":"2025080113593292000_45.9.702.17","doi-asserted-by":"publisher","DOI":"10.1177\/036354659101900311"},{"key":"2025080113593292000_45.9.702.18","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2008.052050"},{"key":"2025080113593292000_45.9.702.19","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2004.011676"},{"key":"2025080113593292000_45.9.702.20","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2003.10.019"},{"key":"2025080113593292000_45.9.702.21","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1302\/0301-620X.69B1.3818742","article-title":"Osteochondral fractures of the talus.
