- Abstract
In general, osteoporosis is evaluated using the bone mineral density (BMD) of the lumbar spine, which can be obtained from dual energy x-ray absorptiometry (DEXA) in lumbar spine radiographs. However, measurements are sometimes difficult in fracture cases, and corrections are necessary among measurement devices or different types of these devices. Furthermore, correlation coefficients vary at different measurement sites. In this study, we attempted to evaluate osteoporosis in tbe pedicle cortex in anteroposterior (AP) views of plain lumbar radiographs.The width of the cortical bone of tbe pedicle (distance between the external and internal margins of the cortical bone) and the cortical bone of the pedicle index in 190 women were determined using AP plain radiographs of the L2 and L3 pedicle, and their relationships with BMD were categorized and investigated by age and BMD (BMD was determined using DEXA).The measurement of the widtb of tbe cortical bone of the pedicle and the cortical bone of the pedicle index for L2 and L3 were found to be suitable for evaluation of the relationship between thickness of tbe cortex of pedicles and osteoporosis. The width of the cortical bone of the pedicle and the cortical bone of the pedicle index for L2 and L3 significantly decreased with age. Correlation coefficients of 0.589 and 0.601 were found between the width of the cortical bone of the pedicle and age and BMD, respectively. Using AP plain lumbar radiographs, the width of the cortical bone of the pedicle for L2 and L3 was determined and a correlation with BMD was obtained. Measurements of the width of the cortical bone of the pedicle may be useful for evaluation of degree of osteoporosis.
