title: [Determination of strength of femoral neck in patients with hip fracture].
abstract: OBJECTIVE
  To study the relationship between the hip fracture and osteoporosis of the aged.
  
  
  METHODS
  The strength of contralateral unfractured proximal femur (Singh index) in 80 patients with hip fractures from 1998 to 2003 were collected, and the patients' age were all over 50 years. At the same time, the strength of proximal femur of 90 patients without fractures were also measured, and the figures were analyzed.
  
  
  RESULTS
  The results showed that the fractures of proximal femur was closely related to osteoporosis in 50-60 age group and 61-70 age group (P<0.01). The relationship was not obvious when the age was over 70 (P>0.05).
  
  
  CONCLUSIONS
  The strength of proximal femur in patients with hip fracture was obvious decreased. The Singh index of proximal femur can be helpful in forecasting the possibility of proximal femur fracture.
