title: [Evaluation of the bone mass in the different types of menopause ].
abstract: OBJECTIVE
  To evaluate the bone mass condition in the different types of menopause and know if there is difference between the groups.
  
  
  METHODS
  Case reports.
  
  
  METHODS
  From September through November 2001 at the Specialties Hospital No. 1, we studied 184 patients with menopause. They were divided in 5 groups: 74 regular menopause, 31 surgical menopause and oophorectomy unilateral, 43 surgical menopause and bilateral oophorectomy, 32 premature menopause, and 4 post-radiotherapy menopause, analyzing the bone mass with a densitometry. The statistical analysis was by descriptive statistics and t student to find the difference between the groups.
  
  
  RESULTS
  We observed 45% with osteopenia y 8% with osteoporosis in regular menopause. In surgical menopause and oophorectomy unilateral group, we found 26% with osteopenia and 6% with osteoporosis. There were 42% with ostepenia and 14% with osteopososis in surgical menopause and bilateral oophorectomy group. In premature menopause, we found 47% with osteopenia and 12% with osteoporosis. In post-radiotherapy menopause, we found 75% with osteopenia and 25% with osteoporosis. All of them with predominance in femur. We did not observe any significant difference between the surgical and the premature menopause groups.
  
  
  CONCLUSIONS
  In a half of patients with menopause we found bone mass decrease with predominance in femur, like osteopenia. There was no significant difference between the surgical and the premature menopause groups.
