title: [Clinical and prognostic aspects of spontaneous fractures in long term care units: a thirty month prospective study. Eastern Gerontology Society].
abstract: OBJECTIVE
  Spontaneous fractures (stress and bone insufficiency fractures) are well described in young healthy patients; however, few studies were conducted in the elderly.
  
  
  METHODS
  A 30-month prospective clinical and epidemiological survey including elderly patients from long-term nursing homes (LTNH) of the Société de Gérontologie de l'Est (70 centers; 11,495 elderly patients in total) was conducted.
  
  
  RESULTS
  Sixty-seven spontaneous fractures were encountered in 30 LTNH (3,052 elderly patients) (five stress fractures of the foot, 62 bone insufficiency fractures). The mean age of bedridden patients was 85 +/- 7 years. The prevalence of spontaneous fractures (calculated from the number of patients admitted consecutively in LTNHs) was 0.34% in the whole population (11,495 beds). When the calculation was based on LTNH reports of spontaneous fractures (3,052 elderly patients), the prevalence reached 1.3%. Fractures of long bones were common in elderly patients and included 15 fractures of the femoral neck, 14 fractures of either the tibia or fibula, 13 fractures of the femoral shaft, and 11 fractures of the humerus. Fractures of the femoral shaft were associated with the highest mortality: seven out of 13 patients died versus two out of 15 patients with regard to fractures of the femoral neck (P < 0.05).
  
  
  CONCLUSIONS
  Bone insufficiency fractures have not the same course in young healthy patients as those in elderly nursing home patients: they more often concern long bones and their prognosis is worse. Means of prevention still have to be defined.
