Therefore, the biomechanical characteristics over the elbow joint surface under long-term loading conditions of baseball pitching can be determined by a measurement of the distribution pattern.<\/jats:p>\n                  <jats:p>Hypothesis: Stress distribution over the elbow joint surface alters with long-term pitching activities.<\/jats:p>\n                  <jats:p>Study Design: Cross-sectional study; Level of evidence, 3.<\/jats:p>\n                  <jats:p>Methods: Computed tomography (CT) imaging data from the dominant elbow of 10 nonthrowing athletes, 10 college baseball fielders, and 10 college baseball pitchers were collected for the current analysis. The distribution of subchondral bone density through the distal articular surface of the humerus was measured using a CT osteoabsorptiometry method. The quantitative analysis of the obtained data focused on location and size of the maximum density area at the articular surface.<\/jats:p>\n                  <jats:p>Results: The maximum density area of subchondral bone across the articular surface of the distal humerus was located in the posterior part of the trochlea in all subjects. This maximum density area was significantly increased in the pitcher group, compared with that in other groups. Additionally, the pitcher group demonstrated a significant distribution of the maximum density area in the anterior part of the capitellum.<\/jats:p>\n                  <jats:p>Conclusion: The results indicate that actual stress across the elbow is concentrated in the posterior part of the trochlea in humans. Baseball pitching may produce excessive or repetitive stress against not only this part, but also the anterior part of the capitellum. The majority of osteochondritis dissecans lesions affecting the elbow are found in the anterior part of the capitellum in throwing athletes. The results may support an important role of mechanical conditions in the cause of elbow osteochondritis dissecans.<\/jats:p>","DOI":"10.1177\/0363546510383487","type":"journal-article","created":{"date-parts":[[2010,11,17]],"date-time":"2010-11-17T23:07:20Z","timestamp":1290035240000},"page":"336-341","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":35,"title":["Long-Term
