Potential shoulder injuries in this age group are proximal humeral epiphysiolysis, glenohumeral instability, rotator cuff dysfunction, and superior labrum anteroposterior lesions. Fatigue, improper biomechanics, and overuse are the most common reasons for these injuries. In the hopes of preventing injury to young pitchers, numerous organizations, including the USA Baseball Medical &amp; Safety Advisory Committee, The American Sports Medicine Institute, Little League Baseball &amp; Softball, and the Long Term Athlete Development Program for Baseball Canada, have developed recommendations on pitching restrictions that include limits on pitch count, pitches per week, pitches per season, and rest between pitching. Awareness by sports medicine providers, coaches, and parents\/guardians of the most up\u2010to\u2010date recommendations on injury prevention and return to play guidelines should reduce the incidence of acute and chronic injuries in adolescent baseball pitchers.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.pmrj.2012.04.005","type":"journal-article","created":{"date-parts":[[2012,7,18]],"date-time":"2012-07-18T17:47:12Z","timestamp":1342633632000},"page":"509-516","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Shoulder
