Purpose: to evaluate the bone mineral density of postmenopausal women with previous hysterectomy and with bilateral ovarian conservation compared to a group of nonhysterectomized naturally menopausal women. Methods: this is a cross-sectional study of bone densitometry (Lunar DPX) in 30 menopausal women hysterectomized when in the premenopause compared with 102 naturally postmenopausal women. Results: the mean age, body mass index, color of the skin, smoking habits, educational level, menarche, parity and previous tubal ligation were similar in the studied groups. Bone mineral density average and the T-score of the three femural sites analyzed by the Bonferroni test did not show significant differences. The bone mineral density average and the T-score of the lumbar spine were analyzed by the Student t test and did not show statistical differences. Conclusion: these findings suggest that premenopausal hysterectomy with bilateral ovarian conservation does not cause an additional reduction in bone mineral content when evaluated in the postmenopause.
