Anthropometric Measurements Obtained for Use in Multiple Regression Analysis
| Parameter | Abbreviation | Measurement (cm) |
|---|---|---|
| Height | HT | Total body height |
| Os coxae width | OC.W | Maximum width of os coxae viewed in CT scout image (projection) |
| Os coxae height | OC.H | Average of maximum heights of left and right sides of os coxae viewed in CT scout image (projection) |
| Os coxae length | OC.L | Average of maximum lengths of left and right sides of os coxae viewed in transverse plane of 3D CT dataset |
| Bitrochanteric breadth | Bi.B | Distance between exterior portions of greater trochanters viewed in CT scout image (projection) |
| Anterior sacral height | ASH | Distance from anterior sacral promontory to apex of sacrum viewed in sagittal plane of 3D CT dataset |
| Sacral width | S.W | Maximum width of sacrum viewed in transverse plane of 3D CT dataset |
| L5 thickness | L5.T | Thickness of L5 vertebra viewed in sagittal plane of 3D CT dataset; measurements were made parallel to anterior surface of vertebral body and approximately 1.5 cm into vertebral body |
| S1 breadth | S1.B | Distance between 2 most lateral points on superior surface of S1 viewed in transverse plane of 3D CT dataset |
| Femoral head perimeter | P | Average of maximum perimeters of left and right femoral heads viewed in sagittal plane of 3D CT dataset |
| Feret's diameter | FD | Measurement is based on femoral head perimeter; this measurement is referred to as caliper length, as it represents longest distance between any 2 points along selected boundary; in this study, perimeter measurement served as this boundary |
| Maximum height of femoral head | Max.H | Maximum height of femoral head viewed in sagittal plane of 3D CT dataset; each measurement represented average for left and right femoral heads |
| Maximum width of femoral head | Max.W | Maximum width of femoral head viewed in sagittal plane of 3D CT dataset; each measurement represented average for left and right femoral heads |
| Humeral head breadth | HH | Distance between exterior portions of right and left proximal humeral heads viewed in CT scout image (projection) |
| Femoral height | FH | Maximum height of femoral bones viewed in CT scout image (projection); each measurement represented average for left and right femoral bones |
