title: Lumbar disc herniation in three patients with cystic fibrosis: a case series.
abstract: BACKGROUND
  To date, lumbar disc herniation has not been reported in the context of cystic fibrosis even though back pain and musculoskeletal problems are very common in patients with cystic fibrosis.
  
  
  METHODS
  We report on three patients with cystic fibrosis who experienced lumbar disc herniation in the course of their disease at ages 19 to 21 years (a 22-year-old Caucasian man, a 23-year-old Caucasian man, and a 21-year-old Caucasian woman). Our third patient eventually died because of her deteriorated pulmonary situation, which was influenced by the lumbar disc herniation as it was not possible for her to perform pulmonary drainage techniques properly because of the pain.
  
  
  CONCLUSIONS
  Lumbar disc herniation can lead to a vicious cycle for patients with cystic fibrosis as it may promote pulmonary infections. This report highlights the need to investigate patients correctly.
