Evaluation of glenohumeral range of motion and humeral retroversion at ages after major change and differences in wrestlers

Purpose: This study aimed to present the change in humeral retroversion (HR) angle (HRA) that occurs childhood and young adulthood potential developmental difference is observed wrestlers. Methods: HRA of dominant non-dominant shoulders (DSHRA NDSHRA, respectively) were measured using ultrasonography a group 30 wrestlers who started wrestling before age 13 years (Group 1), adults, aged between 16–20 years, not actively engaged any branch overhead sports 2) children 11–13 3). Range motion (ROM) degrees all groups compared within each groups. Results: DSHRA (mean: 88.73°, 88.93° 89.40°) values significantly higher than NDSHRA 81.13°, 81.83° 84.37°) (p < 0.001, p 0.001 0,05) Groups I, II III, respectively. Internal rotation total ROM shoulder Group 1 3 those 2. Conclusion: There no significant terms people because natural development or wrestling. are ones. In contrast throwers, characterized by an increase internal rotation, described as “Wrestler’s shoulder.” Level Evidence: III.
