title: [Pathological rupture of the distal biceps tendon after long-term androgen substitution].
abstract: OBJECTIVE
  Is the long-standing use of androgenes able to cause tendon lesions with pathological tendon ruptures?
  
  
  METHODS
  In a case of a rupture of the distal biceps tendon after long-standing testosterone-substitution it is tried to show the connection between the use of androgenes and pathological tendon rupture by the help of the patients treatment documents, the X-rays and sonograms, the histological findings and the results of the clinical examination.
  
  
  RESULTS
  For the first time a case with a rupture of the distal biceps tendon after long-standing testosterone-substitution for the support of a genital transformation is described. Since other tendon damaging factors could be excluded the suspicion of tendon alteration caused by androgenes is obvious.
  
  
  CONCLUSIONS
  Looking at tendon ruptures of professionals and even amateur sportsmen the possible connection between long-standing use of androgenes and tendon damage has to be considered.
