A method of grading trabecular bone loss based on the assessment of five anatomic groups of trabeculae in the proximal end of the femur, which has been used to stratify the risk of femoral neck fracture in senile osteoporosis. It is little used in practice because of the poor intra- and inter-observer agreement and the lack of correlation with bone mineral density as measure by DEXA scans.

With early trabecular resorption, the principal compressive and principal tensile trabecular groups become accentuated; with increased resorption, the tensile trabeculae are decreased; progressive loss of trabeculae leads to disappearance of the outer portion of the principal tensile trabeculae opposite the greater trochanter; resorption of all trabecular groups except the bony trabeculae in the principal compressive group follows, although in severe osteoporosis even these latter trabeculae may be obliterated partially or completely.
