All injuries occurred during training or athletic performances without trauma and caused symptoms that prevented athletic exercises. There were 67 girls (46%) and 80 boys (54%) in the material. About 90% of them had been training for more than one year before the onset of the symptoms; 65% were interested in track and field athletics, 13% in ball games, 11% in skiing, 4% in swimming, and 3% in orienteering. The rest were interested in other sports. About 33% of the injuries were growth disturbances or osteochondroses seen also in other children. About 15% were anomalies, deformities or earlier osteochondritic changes, which caused first symptoms during the physical exercise; 50% were typical overuse injuries that may bother adult athletes, too; 43% of the injuries were localized in ankle, foot and heel, 31% in knee, 8% in back and trunk, 7% in pelvic and hip region, and the rest in other parts of the body. The injuries were generally slight, no permanent disability was noticed. Rest and conservation therapy cured most cases; operative treatment was used in only eight cases.<\/jats:p>","DOI":"10.1136\/bjsm.12.1.4","type":"journal-article","created":{"date-parts":[[2008,12,15]],"date-time":"2008-12-15T19:52:31Z","timestamp":1229370751000},"page":"4-10","source":"Crossref","is-referenced-by-count":40,"title":["Exertion injuries in adolescent athletes."],"prefix":"10.1136","volume":"12","author":[{"given":"S.","family":"Orava","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Puranen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1978,3,1]]},"reference":[{"key":"ref_1","first-page":"127","article-title":"Injury to the throwing arm","volume":"102","author":"Adams, J.E.","year":"1965","unstructured":"Adams, J.
