The correlation between osteoporosis and intervertebral disc degeneration in the spine is not fully understood. In this study the relationship between BMD and disc narrowing is analysed in 359 healthy elderly subjects. The results show there was no significant relationship between hip BMD and intervertebral disc space narrowing. With 48 male subjects who had both DXA and QCT, except disc L1/L2, lumbar disc were more likely to have a narrowed space when lumbar BMD was higher. This observed association could be lumbar spine BMD specific since hip BMD better represents systemic BMD.
