title: The prevalence of spondyloarthropathy in fibromyalgia patients.
abstract: OBJECTIVE
  To document the prevalence of Spondyloarthropathy (SpA) with an evaluation of patients previously diagnosed with fibromyalgia syndrome (FMS).
  
  
  METHODS
  The patients diagnosed with FMS before telephoned and asked three questions to determine for inflammatory back pain. American College of Rheumatology (ACR) Fibromyalgia criteria 1990 and ACR 2010 and for diagnosing patients with SpA; criteria from the European Spondyloarthropathy Study Group (ESSG), and Amor were applied.
  
  
  RESULTS
  FMS was diagnosed according to 1990 ACR criteria in 14 (60.8%) SpA patients who were diagnosed with SpA according to the Amor criteria alone and in 10 (43.4%) patients who were diagnosed according to ESSG criteria alone, while it was diagnosed in 9 (33.3%) patients who were diagnosed with SpA according to Amor and ESSG criteria together and in 15 (65.2%) patients diagnosed with SpA according to Amor and/or ESSG criteria. The most tenderness was experienced in the bilateral shoulder supraspinatus tendon insertion region (57.7%) and in the sacroiliac joint (40.8%). Fourteen (60.8%) patients diagnosed according to ACR 1990 and 17 (51.6%) patients diagnosed according to ACR 2010 had plantar fasciitis and/or Achilles enthesopathy on foot radiography.
  
  
  CONCLUSIONS
  There is a meaningful section of patients who are SpA or FMS and SpA are together in the patients thought to be FMS or the patients diagnosed with FMS according to ACR's criteria can be said.
