[A study of risk factor in osteoporosis, femoral neck fracture and colles' fracture].

This work studied risk factors of osteoporosis, femoral neck fracture and Colles' fracture. The results were compared with those of a healthy group. Milk intake was frequent in the healthy group, but rare in the femoral neck fracture or Colles' fracture group. Most of osteoporosis and femoral neck fracture group were bed ridden, or stayed indoors for a long time before injury. They weighed less and were thin as compared to the healthy group. Decrease of activities of daily living and less body weight were risk factors of osteoporosis and femoral neck fracture, but these risk factors were more predominant in the femoral neck fracture than osteoporosis group. In this study, 74.4% of the patients with femoral neck fracture also had osteoporosis and 33.3% with Colles' fracture had osteoporosis. Colles' fracture was related to injury force and femoral neck fracture was found to be closely related to osteoporosis.
