Twenty-three cases of Little Leaguer's shoulder were reviewed including the history and physical examination findings, as well as bilateral internal and external rotation anteroposterior comparison radiographs of the proximal humerus. The average follow-up was 9.6 months (range, 1.5 to 54), and all patients were observed until they had either returned to baseball or their symptoms had resolved. The average age of the patients in this series was 14 years. The chief complaint in all patients was pain localizing to the proximal humerus during the act of throwing. The average duration of symptoms was 7.7 months. Nineteen patients (83%) were pitchers. Physical examination revealed tenderness to palpation over the proximal humerus in 20 patients (87%), with 16 (70%) demonstrating specific tenderness over the lateral aspect of the proximal humerus. Swelling, weakness, atrophy, and loss of motion were uncommon findings. All 23 patients demonstrated radiographic widening of the proximal humeral physis of the throwing arm on internal and external rotation comparison anteroposterior radiographs of the shoulder. All patients were treated with rest from baseball throwing for an average of 3 months. Twenty-one of the 23 patients (91%) returned to playing baseball and were asymptomatic. The classic radiographic finding of widening of the proximal humeral physis can easily be seen on bilateral anteroposterior internal and external rotation radiographs of the proximal humerus. Rest from throwing for at least 3 months is recommended, followed by a gradual return to throwing in an asymptomatic shoulder.

Little Leaguer’S Shoulder

With the advent of Little League Baseball there has developed an awareness of the adverse effect that excessive pitching can have on the growth areas about the shoulder and elbow of the preadolescents. The terms "Little Leaguer's Shoulder" and "Little Leaguer's Elbow" describe distinct clinical entities. In addition to reviewing these problems, an attempt has been made to identify their cause. Specifically, clinical and radiological observations made on a group of 49 preadolescent pitchers who participated in a low-competition, recreational baseball program are reported. Although the data are not conclusive, we believe our observations indicate that the preadolescent should avoid pitching in an intensely competitive situation.

Objectives: The increased humeral retroversion on the dominant side in throwing athletes is thought to result from repetitive throwing motion. In the previous studies, the degree of increased humeral retroversion was various, suggesting that other factors may affect humeral retroversion. Little Leaguer’s shoulder, which is rotational stress fracture of the proximal humeral epiphyseal plate, may change humeral retroversion. The purpose of this study was to investigate effect of Little Leaguer’s shoulder on humeral retroversion. Methods: Ten high-school baseball players (average, 16.6 years; range, 16 to 18 years), who had had Little Leaguer’s shoulder during elementary or junior high schools (average, 12.6 years; range, 11 to 15 years), were enrolled in the study. As a control group, 22 high-school baseball players (average, 16.9 years; range, 16 to 18 years), who have never had shoulder or elbow pain, were included in this study. Humeral retroversion was ultrasonographically measured on the dominant and non-dominant sides. Humeral retroversion was compared between dominant and non-dominant shoulders with paired t-test. Side-to-side difference in humeral retroversion was compared between Little Leaguer’s shoulders and control group with unpaired t-test. Results: Humeral retroversion was significantly greater on the dominant side than on the non-dominant side in both Little Leaguer’s shoulder (Dominant, 104°±8°; Non-dominant, 84°±12°; P < .001) and control groups (Dominant, 91°±13°; Non-dominant, 81°±10°; P < .001). The side-to-side difference in humeral retroversion in Little Leaguer’s shoulder group (20°±10°) was significantly greater than that in control group (10°±10°, P = .02). Conclusion: Humeral retroversion was increased with repetitive throwing motion without any symptom in the shoulder and elbow joint. Additional increase in humeral retroversion was made when the players had had Little Leaguer’s shoulder in elementary or junior high school.
