Overview
Classification
- The main established classification system for osteoporosis is based on bone marrow density (BMD) in patients. The patients would be classified upon the site and method of measurements; also the used equipment and reference group of people may play roles. Finally, the major value using for classification of osteoporosis is T-score. T-score would be defined as "patient measured BMD value minus the reference BMD value (sex-matched and preferably for youth) divided the reference SD (sex-matched and preferably for youth)".
- The common classification of osteoporosis upon BMD measured T-score is as following:
- Lu and colleagues have found that pure using of T-score and comparing to reference normative data aged 20-29 years, as world health organization (WHO) criteria, is very inconsistent. Compared to other classification systems, it is better to standardize the normative data, perhaps to older population; and also complex the findings of multiple sites BMD measures, in order to obtain a better classification systam.
