Table 2 Definition and description of sacrum parameters adopted from Kanika et al. (2011) and Shreekrishna et al. (2013) (refer to Fig. 1 for image description)
From: Stature estimation of the Malaysian population based on sacrum CT scans
No. | Parameter(s) | Description |
|---|---|---|
P1 | Sacral basal width | Maximum transverse midpoint distance of the superior surface of sacrum that comprising of the two alae |
P2 | Transverse diameter S1 body | Maximum transverse midpoint diameter of the articular surface of the body of first sacral vertebra (S1) |
P3 | Anteroposterior (A-P) diameter S1 body | Antero-posterior distance from the midpoint of sacral promontory up to the midpoint on the posterior border of S1 body |
P4 | Right ala width | Maximum straight distance of the right sacral ala from the right transverse diameter of the S1 body |
P5 | Left ala width | Maximum straight distance of the left sacral ala from the left transverse diameter of the S1 body |
P6 | Sacral height | The midpoint of the sacral promontory to the middle of antero-inferior border of the fifth sacral vertebra |
P7 | Right auricular surface length | Maximum distance of the superior-inferior inner border of auricular surface on right lateral aspect of sacrum |
P8 | Left auricular surface length | Maximum distance of the superior-inferior inner border of auricular surface on left lateral aspect of sacrum |
P9 | Right ala A-P length | Antero-posterior distance from the lateral posterior most point up to lateral anterior most point on the superior border of the right ala |
P10 | Left ala A-P length | Antero-posterior distance from the lateral posterior most point up to lateral anterior most point on the superior border of the left ala |
