Unusual fractures associated with osteoporosis in premenopausal women.
Two premenopausal women (aged 40 and 34 years) and multiple undisplaced, often asymptomatic fractures of the femurs, ribs, metatarsals and other bones. The fractures, which appeared on roentgenograms as transverse radiolucent zones with variable callus formation, healed slowly or not at all despite treatment with calcium and vitamin D. They resembled pseudofractures (Looser's transformation zones) radiologically, but the biochemical and histologic findings were those of idiopathic osteoporosis rather than osteomalacia. Since neither patient had been subjected to unusual stress it was concluded that the fractures had resulted from normal activity in abnormal bone.
