title: [Relationship between fracture risk evaluated by FRAX tool and spinal curvature].
abstract: OBJECTIVE
  To investigate the relationship between the risk of osteoporotic fracture in old people and the spinal morphology.
  
  
  METHODS
  From June 2010 to January 2011, 107 old people's BMD of femoral neck were measured by Dual energy X-ray. A questionnaire survey on fracture risk factors of the 107 aged and data collection were adopted. Among the aged,41 were male and 66 were female,ranging in age from 48 to 82 years old,with an averaged of (67 +/- 6) years old. The fracture risk assessment tools (FRAX) recommended by WHO were adopted. A risk assessment on osteoporotic fracture in old people was done,followed with the calculation of the probability of the hip fracture and the main bone fractures (spine,hip,forearm or shoulder fractures) in ten years. The angles of spine vertebra, spine curvature in the upright positions of the old people were measured by using Spinalmouse. The correlation analysis along with curve fitting analysis between the probability of fracture risk and included angles of spine vertebra, spine curvature were done.
  
  
  RESULTS
  The probability of osteoporotic fracture had a positive relation with thoracic vertebra T7 and T8, thoracic spine curvature,lumbar curvature and incline angle in upright position (P < 0.05).
  
  
  CONCLUSIONS
  The old people's morphological characteristics of spine have the ability to reflect the risk level o osteoporotic fracture.
