title: Longitudinal microradioscopic comparisons on endosteal and juxtaendosteal bone loss in premenopausal and postmenopausal women, and in those with end-stage renal disease.
abstract: Endosteal bone resorption is the principal mechanism of bone loss in involutional osteoporosis and in renal osteodystrophy. In the cortical bone it is often accompanied by juxtaendostal bone resorption. Using fine-detail radiographs and x6 magnified viewing, longitudinal radiographic observations and measurements were made on these two forms of bone resorption in the metacarpals II, III, and IV in three groups of women: (1) premenopausal, (2) postmenopausal, and (3) patients with end-stage renal disease. Bone loss was found to be negligible in the premenopausal women, but in postmenopausal and renal patients both endosteal and juxtaendosteal bone resorption were frequently demonstrable. It is suggested that when a base-line fine-detail hand radiograph is obtained at the time of the menopause, follow-up radiographs may permit detection of relatively early endosteal and juxtaendosteal bone loss by comparing the respective areas in metacarpals with those of the original radiograph. Since the methodology does not require expensive equipment, has a low intraobserver error and is simple to perform, it may deserve to be further evaluated in studies aimed at developing a simple and inexpensive approach as a screening method for early detection of postmenopausal osteoporosis.
