Bone mineral density of females with single and multiple osteoporotic vertebral compression fractures. The T-score values from dual-energy X-ray absorptiometry of lumbar spine and hip joint in 387 females with osteoporotic vertebral compression fractures. In the age group of 70–80 years old, MSVF-3/m showed significantly lower T-score values than MSVF-2 and SSVF. SSVF: single segment vertebral fracture; MSVF-2: multi-segment vertebral fractures involving two vertebra; MSVF-3/m: multi-segment vertebral fractures involving three or more vertebra. ns: not significantly different; *p < 0.05; **p < 0.01
