Abstract
We enrolled 76 healthy, premenopausal women over age 46, performed transilial bone biopsies after tetracycline labeling, and during a period of 9.5Â years, we re-biopsied 51 of them who passed through menopause and remained healthy the entire time. We also obtained serum biochemical measurements, and serial DXA exams during the period of observation. The dynamic bone histomorphometry demonstrated a doubling of bone remodeling, and increases in serum bone markers at the time of the second biopsy. Lumbar spine bone density also declined, and there were significant correlations between serum markers and histomorphometry variables. The data demonstrate that healthy menopause results in an important increase in bone remodeling, and a loss of bone density. We do not fully understand the mechanisms of these transmenopausal changes, but the data provide some clues that are helpful.
