Finite element modeling of the ligaments of the thoracolumbar spine (from calibration against Cook et al31).
Ligament | Stiffness, N/mm | No. of Elements |
Anterior longitudinal | 3–30a | 3 |
Posterior longitudinal | 3–30a | 3 |
Flaval | 3–90a | 3 |
Capsular | 500–2000a | 10 |
Supraspinous | 1400a | 4 |
Interspinous | 3–21a | 3 |
