VERTEBRAL bodies are frequent sites of pyogenic osteomyelitis in the adult.1-3 Anatomically, lumbar vertebrae are most commonly involved, followed by thoracic and, rarely, cervical vertebrae. In most series, vertebral osteomyelitis occurs in the setting of urinary tract disease2,4,5 or intravenous (IV) drug use.2,3
The preponderant pathogen in pyogenic osteomyelitis is Staphylococcus aureus,1,2 followed by Gram-negative rods usually from a urinary tract focus.5Staphylococcus epidermidis is a rare cause of osteomyelitis.4,5 The first report of osteomyelitis in hemodialysis patients implicated S epidermidis in three of five cases, either as the sole etiologic agent or combined with S aureus or Pseudomonas aeruginosa.6 We describe two cases of cervical osteomyelitis due to S epidermidis in long-term hemodialysis patients.
