摘要: Lumbar spine and femoral neck bone densities of women, aged 35-65, were measured by dual photon densitometry. After exclusion women with spinal other abnormalities, this study included 233 subjects: 60 menstruant, 91 who underwent natural menopause (56 more than 2 years post-menopause), 45 bilaterally oophorectomized, 37 hysterectomized without bilateral oophorectomy. No significant differences found between the age-normalized average early postmenopausal, late postmenopausal women; nor was there a difference rates their loss. The significantly lower those normals. oophorectomized patients. loss, however, comparable in all groups studied. use estrogen progestin associated higher lumbar but showed no effect any groups.
