A biomechanical comparison of the female and male sacroiliac joint (SIJ).37
|
Biomechanical Aspects |
Female |
Male |
| SIJ motions | More rotational | More translational |
| Angular range of motions | Higher (Up to 2.8°) | Lower (Up to 1.2°) |
| Sacral cartilage | Thicker | Thinner |
| Iliac bone cortical layer | Thinner | Thicker |
| SIJ surface area | Lesser | Greater |
| Pelvis | Wider, shorter | Narrower, taller |
| Sciatic notch | Wider | Narrower |
| Acetabula | Wider | Narrower |
| Pubic angle | Larger (90° to 100°) | Smaller (50° to 80°) |
| Interosseous sacroiliac ligament | Larger | Smaller |
| Anterior sacroiliac ligaments | Smaller | Larger |
| Posterior sacroiliac ligaments | Smaller | Larger |
