It considers the continuous character of vertebral fractures and makes a meaningful interpretation of follow-up radiographs possi- ble. Furthermore, inevitably arbitrary decisions regarding wedge, endplate, or crush deformities, as assessed in some grading schemes, are not necessary since most fractures Fig. The repro- ducibility of the method for the diagnosis of prevalent and incident vertebral fractures was found to be high, with in- traobserver agreement of 93–99% and interobserver agree- ment of 90–99%. This indicates that close agreement among readers can be reached using this standardized visual semi- quantitative grading method, and that subjectivity in the readings can be reduced. This accounts for experienced and relatively inexperienced readers with reasonable re- sults. There are limitations of this semiquantitative grading scheme that may also apply to other standardized ap- proaches. For example, from the morphometric data on normal subjects we know that vertebrae in the middle tho- racic spine (especially in women) and thoracolumbar junc- tion (especially in men) are slightly more wedged than in other regions. As a result these nor- mal variations may be misinterpreted as mild vertebral de- formities, thereby falsely increasing prevalence values for vertebral fractures. Accurate di- agnosis of prevalent fractures which requires distinguish- ition [3, 42]. Typically six points are used to derive the an- ing between normal variations and the degenerative changes terior height (h ), the central (middle or middle-vertebral, a from true fractures still depends on the experience of the h ) height, and the posterior height (h ; Fig. It has been argued that the diagnosis of mild ver- clusively quantitative approach has, however, a number of tebral fractures (grade 0. The reader may sometimes feel that even duction in vertebral heights such as 15–20% or 3 SD de- though a further height reduction is seen in a previous ver- crease. Furthermore, a significant number of false positives tebral fracture, it may not be justified to assign a higher are found with quantitative techniques. The choice of point fracture grade on a serial radiograph, since some degree of placement in the quantitative technique, but especially the settling or remodeling generally occurs. Therefore in gen- choice of the threshold for defining vertebral deformity, eral, serial radiographs including the baseline radiograph gives results that vary in specificity and sensitivity. Most of a patient should be viewed together so that incident of the moderate to severe deformities are detected by both fractures can be readily identified as only those progres- techniques. However, only expert visual evaluation can sive changes that lead to a full increase in deformity grade detect mild and subtle deformities, as well as appreciate or from a questionable deformity (grade 0. The strength of a semiquantitative approach is that it makes use of the entire spectrum of visible features that Quantitative morphometry and its comparison are helpful in identifying deformities [15, 49].
