[Therapy-resistant lumbago]

The 71-year-old female patient was hospitalized owing to a therapy-resistant lumbo-spondylogenic syndrome. Radiology with increased infection parameters gave rise to the suspicion of a bacterial spondylodiscitis L1/L2. Puncture of the vertebral body as well as blood cultures established proof of yersinia enterocolitica. In spite of immediate adequate antibiosis, by means of "Ciprofloxacin" i.v. spondylodesis of the lumbar spine had to be carried out in order meet the threat of instability. Spondylodiscitis is an extremely rare manifestation of a yersinia infection, only few cases have been described so far in medical literature.
