Bottom Line: CHL thickness resulted comparable in the dominant and non-dominant arms (11.3 ± 4.4 mm vs. 13 ± 4.2, p > 0.05).No statistically significant differences between players and control group were found (p = 0.71).In a-symptomatic non-elite junior tennis players only minor shoulder abnormalities were found.

ABSTRACT

Background: Tennis is believed to be potentially harmful for the shoulder, therefore the purpose of this study is to evaluate the anatomy of the rotator cuff and the coraco-humeral ligament (CHL) in a-symptomatic non-elite junior tennis players with high-resolution ultrasound (US).

Methods: From August 2009 to September 2010 n = 90 a-symptomatic non-elite junior tennis players (mean age ± standard deviation: 15 ± 3) and a control group of age- and sex- matched subjects were included. Shoulder assessment with a customized standardized protocol was performed. Body mass index, dominant arm, years of practice, weekly hours of training, racket weight, grip (Eastern, Western and semi-Western), kind of strings were recorded.

Results: Abnormalities were found at ultrasound in 14/90 (15%) players. Two players had supraspinatus tendinosis, two had subacromial impingement and ten had subacromial bursitis. CHL thickness resulted comparable in the dominant and non-dominant arms (11.3 ± 4.4 mm vs. 13 ± 4.2, p > 0.05). Multivariate analysis demonstrated that no association was present among CHL thickness and the variables evaluated. In the control group, abnormalities were found at ultrasound in 6/60 (10%) subjects (sub-acromial bursitis). No statistically significant differences between players and control group were found (p = 0.71).

Conclusion: In a-symptomatic non-elite junior tennis players only minor shoulder abnormalities were found.

Mentions: Players’ characteristics relative to sex, dominant arm, years of practice, hours of training per week, grip, racket weight, type of backhand and body mass index are reported in Table 1.Abnormalities were found at ultrasound in 14/90 (15%) players. The majority of the lesions were located in the dominant arm (n = 10), whereas only few of them were in non-dominant arm (n = 4). No tendon tears were detected. Two players had supraspinatus tendinosis. Sub-acromial bursitis was present in 10 players (Figure 3). Two players had subacromial impingement. No rotator-cuff muscular atrophy was found. Coracohumaral thickness resulted comparable in the dominant and non-dominant arm of the players (11.3 ± 4.4 mm in the dominant arm versus 13 ± 4.2 in the non-dominant arm, p > 0.05). Multivariate analysis demonstrated that no association was present among coracohumaral thickness or lesions detected at sonography and body mass index, years of practice, weekly hours of training, racket weight, strings and dominant arm. In the control group, abnormalities were found at ultrasound in 6/60 (10%) subjects (sub-acromial bursitis). No statistically significant differences between players and control group were found (two-tailed P value = 0.71). Coracohumeral thickness was not statistically different in the two groups (p > 0.05).
