title: [Breakdancer's "Headspin Hole" - first description of a common overuse syndrome].
abstract: BACKGROUND
  Several typical injuries due to breakdancing have been described in medical literature, but until now the "headspin hole" has not been mentioned.
  
  
  METHODS
  We conducted internet research and interviewed 106 breakdancers.
  
  
  RESULTS
  60.4 % of the breakdancers suffered from overuse of the scalp due to the headspin. Loss of hair was found in 31.1 % and painless lumps on the head in 23.6 %. Inflammation of the scalp was reported in 36.8 %.
  
  
  CONCLUSIONS
  The "Headspin Hole" is a common overuse syndrome of the scalp specific to headspins causing hair loss, inflammation and lumps on the skull.
