title: Ultrasonographic evaluation of the shoulder in elite wheelchair tennis players.
abstract: BACKGROUND
  Wheelchair tennis has been identified as a high-risk sport for shoulder injury, so understanding shoulder pathology in these athletes is important.
  
  
  OBJECTIVE
  This study investigated the incidence and pattern of shoulder injuries in wheelchair tennis players using high-resolution ultrasonography.
  
  
  METHODS
  Descriptive study.
  
  
  METHODS
  International Wheelchair Tennis Open.
  
  
  METHODS
  33 elite-level wheelchair tennis players.
  
  
  METHODS
  Wheelchair tennis players completed a self-administered questionnaire, and shoulders of each athlete were investigated using high-resolution ultrasonography (linear probe 7.5 MHz).
  
  
  RESULTS
  The most common pathology in the dominant shoulder was acromioclavicular pathology, in 21 players (63.6%). Full-thickness rotator-cuff tears involving the supraspinatus were found in 8 dominant shoulders and 6 nondominant shoulders. There were no correlations between identified shoulder pathology and the different variables studied, such as age, training time per day, length of wheelchair use, and length of career as a wheelchair tennis player.
  
  
  CONCLUSIONS
  High prevalence of rotator-cuff and acromioclavicular pathology was found by ultrasonographic examination in the elite wheelchair tennis players in both dominant and nondominant shoulders. A high index of suspicion of these pathologies in wheelchair athletes is required.
