title: Steroid-Induced Osteonecrosis in Dermatology: A Review.
abstract: BACKGROUND
  Steroid-induced osteonecrosis is unpredictable and highly morbid.
  
  
  METHODS
  MEDLINE (Ovid) and PubMed search for relevant literature.
  
  
  RESULTS
  Oral steroid doses typically considered to be associated with the condition are >20 mg of prednisone (or equivalent) per day or >2 g within a period of 2 to 3 months. Symptoms may be vague.
  
  
  CONCLUSIONS
  Dermatologists must exercise a high degree of clinical suspicion and warn patients about steroid-related risks and conditions for follow-up.
