title: [Sacral insufficiency fractures].
abstract: BACKGROUND
  The spontaneous osteoporotic fracture of the sacrum, known as a sacral insufficiency fracture (SIF) was first described as an unrecognized syndrome of the elderly by Laurie, in 1982. Numerous case histories and a few series of cases have been discussed in medical journals; however, none have been reported in Hungary.
  
  
  OBJECTIVE
  To delineate the leading diagnostic steps in the recognition of SIF and review the therapeutic guidelines. CASE HISTORIES, METHODS: Between January 2009 and the first six months of 2010 11 cases of SIF were diagnosed at the National Center for Spinal Disorders. We examined the clinical aspects of the illness, the radiological modalities, the fracture markings, the pace of recovery and duration.
  
  
  RESULTS
  The 11 patients were found to have various SIF predestining etiological factors and the following classic fractures--H-type, unilateral, horizontal, unilateral-horizontal and vertical as well as a bilateral pattern. In cases often not showing obvious clinical symptoms and in cases resulting in conventional radiological examinations of low sensitivity and specificity, we used mapping techniques in setting up the exact diagnosis.
  
  
  CONCLUSIONS
  If we consider SIF from patient history and known risk factors, diagnostic procedure (primer original) may be shortened and a number of unnecessary tests (biopsy) may be avoided.
