Abstract

INTRODUCTION: Trabecular bone has a high turnover rate about 8 times that of cortical bone. The aim of this study was to establish a dual energy x-ray ABSORPTIOMETRY (DXA)t echnique for measuring OS CALCIS bone mineral density (BMD).METHODS: An OS CALCIS phantom was used for in-vitro precision. Precision was estimated from repeat studies in ten subjects. Thirty-one female subjects who were referred for SPINE FEMUR BMD assessment had their OS CALCIS measured. T-scores for the SPINE and FEMUR were calculated. The T-score for the OS CALCIS was calculated using twenty-one young normal females. Patient BMD was classified according to the World Health Organization (WHO) criteria for assessing patient BMD relative to young reference data.RESULTS: In-vitro and in-vivo precise (CV ≤ 1.1 %) results were achieved. Moderate correlations between the OS CALCIS, SPINE and FEMUR were found. Using the T-score values, the number of patients defined as osteoporotic varied from 16% for the total FEMUR to 29% for neck of FEMUR and 45% for OS CALCIS. The combination of SPINE and total FEMUR diagnosed a higher number of patients at fracture risk. Adding the OS CALCIS to SPINE/total FEMUR Measurements a further number of subjects at fracture risk were identified.DISCUSSION: from our findings it can be concluded that assessment of OS CALCIS may predict risk of fracture at other sites at an earlier stage.
