Tagliafico A, Cadoni A, Bignotti B, Martinoli C - BMC Musculoskelet Disord (2014)

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.

On the left side are represented the 8 facets of the butt cap and the reference points (base knuckle of the index finger and heel pad) on the hand to identify the different grips. On the right side the Eastern and Western Grips are illustrated: note that the hand of the players is in the same position while the inclination of the racket changes. Other grips are described in the text. The blue hexagons are positioned in critical areas (base knuckle and heel pad).

Figure 2: On the left side are represented the 8 facets of the butt cap and the reference points (base knuckle of the index finger and heel pad) on the hand to identify the different grips. On the right side the Eastern and Western Grips are illustrated: note that the hand of the players is in the same position while the inclination of the racket changes. Other grips are described in the text. The blue hexagons are positioned in critical areas (base knuckle and heel pad).

Mentions: Concerning the grip we registered the four basic single-handed grips used to hit the forehand: Continental, Eastern, Semi-western and Full Western. For each grip, the player places the base knuckle of the index finger and the heel pad of the palm on the grip bevel of the racquet. Different grips are defined on the base of the location of the base knuckle of the index finger on the eight faces of the racket grip (Figure 2). Grip types were defined according to the International Tennis Federation definitions [1,21] and checked for accuracy by two tennis instructor in consensus who observed the players holding the racket at rest and during the game.
